different pitches during a live-midi performance
Dear community,
I want to know, if it could be possible, to get different pitches for e.g. fis and ges during a live-midi performance.
What I desire, is to influence the pitch by a controller, e.g. the left piano-pedal.
I'm not speaking of pitch-bending, I really mean an exact, clearly regognizable pitch, when You press a key with od without this controller.
Is it possible?

Yes, certainly. But tell us more what you have in
mind.
I assume your keyboard would be a MIDI controller,
correct?
An obvious choice would be a MIDI foot controller
input through the keyboard, or a MIDI footswitch in conjunction with a foot
controller or a portamento pedal.
If you need specific pitches from the pedal(s) -
even from a standalone portamento pedal, Csound could "round" the pedal to the
nearest pitch, or indeed add a rounded percentage to the current keyboard
pitch.
There are many possibilities.

Re: Re: different pitches during a live-midi performance
Dear Art, thanks for Your answer. I have attached a small example to this mail. I use there a scale with 17 pitches per octave but (as You all know)I do have only 12 pitches per octave on the keyboard. I would like to allocate the black key two pitches and I would like to change this with the pressure of the una-corda-pedal (the left pedal). While pressing the left pedal down, I would like to get a lower pitch, in the other case, the higher pitch.
But I have no idea, how to do it with csound. So, I really need Your help! At least I hope, that my idea of negotiating the limitation of 12 pitches per octave in this way will be interesting for other musicians to.

Hello, Stefan,
Here's what I'd try:
In header:
gkpedal init 0
and after your massign:
massign 64, 2
(or whatever controller # your foot pedal is,
assign its data to instr 2. The massigns may be tricky.)
You should be able to use any type of foot pedal
your MIDI keyboard will accept.
Make a completely new instrument that receives
MIDI data only on controller 64 (or whichever # you choose):
instr 2
gkpedal ctrl7 1, 64, 0, 1
endin
The above instrument is always receiving foot
controller data.
In the score, add:
i2 0 3600
In your instr1, add (at beginning):
ipedal = i(gkpedal)
and later (after icps computed):
if imnn != 60 and imnn != 62 and notnum
...... igoto skip ; this is a list of *all your black MIDI key
numbers*!
icps = (ipedal > 0? icps - (icps * .1): icps +
(icps * .1)
skip:
In the above, ".1" is the percentage of the
frequency you wish to add or subtract from your "basic pitch"
(12tet).
You may want to make some other kind of pitch
adjustment. For example you might put the low version (freq) of the black key
pitch in your table, then multiply it by some factor if the pedal were up
(gkpedal == 0):
icps = (ipedal > 0? icps + (icps * .1):
icps)
Or perhaps you want different groups of "igoto"
branches, where for example all F#'s modify in one way, all G#'s in
another.
Let me know how it works out for you.

Hello, Stefan,
Here's what I'd try:
In header:
gkpedal init 0
and after your massign:
massign 64, 2
(or whatever controller # your foot pedal is,
assign its data to instr 2. The massigns may be tricky.)
You should be able to use any type of foot
pedal your MIDI keyboard will accept.
Make a completely new instrument that
receives MIDI data only on controller 64 (or whichever # you
choose):
instr 2
gkpedal ctrl7 1, 64, 0, 1
endin
The above instrument is always receiving foot
controller data.
In the score, add:
i2 0 3600
In your instr1, add (at
beginning):
ipedal = i(gkpedal)
and later (after icps computed):
if imnn != 60 and imnn != 62 and
notnum ...... igoto skip ; this is a list of *all your black MIDI key
numbers*!
icps = (ipedal > 0? icps - (icps * .1): icps
+ (icps * .1)
skip:
In the above, ".1" is the percentage of the
frequency you wish to add or subtract from your "basic pitch"
(12tet).
You may want to make some other kind of pitch
adjustment. For example you might put the low version (freq) of the black
key pitch in your table, then multiply it by some factor if the pedal were
up (gkpedal == 0):
icps = (ipedal > 0? icps + (icps * .1):
icps)
Or perhaps you want different groups of "igoto"
branches, where for example all F#'s modify in one way, all G#'s in
another.
Let me know how it works out for
you.

Dear Art, thanks for Your answer. I have attached a
small example to this mail. I use there a scale with 17 pitches per
octave but (as You all know)I do have only 12 pitches per octave on the
keyboard. I would like to allocate the black key two pitches and I
would like to change this with the pressure of the una-corda-pedal (the
left pedal). While pressing the left pedal down, I would like to get a
lower pitch, in the other case, the higher pitch. But I have no idea,
how to do it with csound. So, I really need Your help! At least I hope,
that my idea of negotiating the limitation of 12 pitches per octave in
this way will be interesting for other musicians
to. Thanks Stefan :

Yes, certainly. But tell us more what you
have in mind.
I assume your keyboard would be a MIDI
controller, correct?
An obvious choice would be a MIDI foot
controller input through the keyboard, or a MIDI footswitch in
conjunction with a foot controller or a portamento pedal.
If you need specific pitches from the
pedal(s) - even from a standalone portamento pedal, Csound could "round"
the pedal to the nearest pitch, or indeed add a rounded percentage to
the current keyboard pitch.
There are many possibilities.

[Csnd] different pitches during a live-midi performance
Dear community,
I want to know, if it could be
possible, to get different pitches for e.g. fis and ges during a
live-midi performance.
What I desire, is to influence the pitch by
a controller, e.g. the left piano-pedal.
I'm not speaking of
pitch-bending, I really mean an exact, clearly regognizable pitch,
when You press a key with od without this controller.
Is it
possible?

Hello, Stefan,
Iain is correct (he always is, and you can totally count
on his advice regarding realtime). My bad. *Controller* 64 is the foot
controller/switch for MIDI.
Suggestions:
Delete line 14 *as well as 13*.
In instrument 2, substitute:
gkpedal ctrl7 2, 64, 0, 1
Then play your keyboard on channel 1, but put the foot
controller on channel 2. (Alternately, put the foot controller on any channel
except #1; number the instrument the same as the channel and give the controller
the same number also (e.g., gkpedal ctrl7 10 for channel 10).) This should send
all keyboard data to instr 1, pedal data to instr 2.
Frankly, I've always had trouble getting insnum to trigger
notes, and never use it. If the above doesn't work, I'd try another approach:
use an always-on instrument 1 that handles *all* midi input; when noteon's are
received, it schedules events (through event or schedkwhen) for instrument
2. Working at k-rate, it also handles pedal-data (as in your i2).
All of my live performance works use this principle; you
can look at many .csd's at my website, arthunkins.com, if you'd
like.
Let us know how you get on.

Hello, Stefan,
Here's what I'd try:
In header:
gkpedal init 0
and after your massign:
massign 64, 2
(or whatever controller # your foot pedal
is, assign its data to instr 2. The massigns may be
tricky.)
You should be able to use any type of foot
pedal your MIDI keyboard will accept.
Make a completely new instrument that
receives MIDI data only on controller 64 (or whichever # you
choose):
instr 2
gkpedal ctrl7 1, 64, 0, 1
endin
The above instrument is always receiving
foot controller data.
In the score, add:
i2 0 3600
In your instr1, add (at
beginning):
ipedal = i(gkpedal)
and later (after icps
computed):
if imnn != 60 and imnn != 62 and
notnum ...... igoto skip ; this is a list of *all your black MIDI key
numbers*!
icps = (ipedal > 0? icps - (icps * .1):
icps + (icps * .1)
skip:
In the above, ".1" is the percentage of the
frequency you wish to add or subtract from your "basic pitch"
(12tet).
You may want to make some other kind of
pitch adjustment. For example you might put the low version (freq) of
the black key pitch in your table, then multiply it by some factor if
the pedal were up (gkpedal == 0):
icps = (ipedal > 0? icps + (icps * .1):
icps)
Or perhaps you want different groups of
"igoto" branches, where for example all F#'s modify in one way, all G#'s
in another.
Let me know how it works out for
you.

pitches during a live-midi performance
Dear Art, thanks for Your answer. I have attached a
small example to this mail. I use there a scale with 17 pitches per
octave but (as You all know)I do have only 12 pitches per octave on
the keyboard. I would like to allocate the black key two pitches
and I would like to change this with the pressure of the
una-corda-pedal (the left pedal). While pressing the left pedal down,
I would like to get a lower pitch, in the other case, the higher
pitch. But I have no idea, how to do it with csound. So, I really
need Your help! At least I hope, that my idea of negotiating the
limitation of 12 pitches per octave in this way will be interesting
for other musicians to. Thanks Stefan :
2009/7/2 Art Hunkins <abhunkin@...>
Yes, certainly. But tell us more what
you have in mind.
I assume your keyboard would be a MIDI
controller, correct?
An obvious choice would be a MIDI foot
controller input through the keyboard, or a MIDI footswitch in
conjunction with a foot controller or a portamento
pedal.
If you need specific pitches from the
pedal(s) - even from a standalone portamento pedal, Csound could
"round" the pedal to the nearest pitch, or indeed add a rounded
percentage to the current keyboard pitch.
There are many
possibilities.

Subject: [Csnd] different

Dear community,
I want to know, if it could be
possible, to get different pitches for e.g. fis and ges during a
live-midi performance.
What I desire, is to influence the pitch
by a controller, e.g. the left piano-pedal.
I'm not speaking of
pitch-bending, I really mean an exact, clearly regognizable pitch,
when You press a key with od without this controller.
Is it
possible?
Insert movie times and more without leaving Hotmail®. See how.

Re: Re: Re: different pitches during a live-midi performance
Dear Art, many thanks, again, for Your fast answer. There is one more thing, I don't understand: How can I put the foot-controller to channel two? Or is this already done with
gkpedal ctrl7 2, 64, 0, 1
2009/7/7 Art Hunkins <abhunkin@...>
Hello, Stefan,
Iain is correct (he always is, and you can totally count
on his advice regarding realtime). My bad. *Controller* 64 is the foot
controller/switch for MIDI.
Suggestions:
Delete line 14 *as well as 13*.
In instrument 2, substitute:
gkpedal ctrl7 2, 64, 0, 1
Then play your keyboard on channel 1, but put the foot
controller on channel 2. (Alternately, put the foot controller on any channel
except #1; number the instrument the same as the channel and give the controller
the same number also (e.g., gkpedal ctrl7 10 for channel 10).) This should send
all keyboard data to instr 1, pedal data to instr 2.
Frankly, I've always had trouble getting insnum to trigger
notes, and never use it. If the above doesn't work, I'd try another approach:
use an always-on instrument 1 that handles *all* midi input; when noteon's are
received, it schedules events (through event or schedkwhen) for instrument
2. Working at k-rate, it also handles pedal-data (as in your i2).
All of my live performance works use this principle; you
can look at many .csd's at my website, arthunkins.com, if you'd
like.
Let us know how you get on.

Re: Re: Re: Re: different pitches during a live-midi performance
Some parts of this message have been removed.
Learn more about Nabble's security policy.
Stefan,
Without declaring massign, instr1 receives all the
channel 1 data; instr2 all of the channel 2 data.
In this scenario, you'll need to set channel 2
either on the foot controller itself, or set controller 64 (or whichever) to
channel 2 on your keyboard. (The keyboard
otherwise outputs on channel 1.)
If this is not possible, or doesn't work, next
try:
Put:
gkpedal ctrl7 1, 64, 0, 1
as the first line of instr 1.
Restore your
massign 0, 1
Remove instr 2 and its note
If these don't work, I'd advise going to the
alternate method I suggested previously. (I'll also do some actual
experimentation of my own at that point.)

Hello, Stefan,
Here's what I'd try:
In header:
gkpedal init 0
and after your massign:
massign 64, 2
(or whatever controller # your foot
pedal is, assign its data to instr 2. The massigns may be
tricky.)
You should be able to use any type of
foot pedal your MIDI keyboard will accept.
Make a completely new instrument
that receives MIDI data only on controller 64 (or whichever # you
choose):
instr 2
gkpedal ctrl7 1, 64, 0, 1
endin
The above instrument is always
receiving foot controller data.
In the score, add:
i2 0 3600
In your instr1, add (at
beginning):
ipedal = i(gkpedal)
and later (after icps
computed):
if imnn != 60 and imnn != 62
and notnum ...... igoto skip ; this is a list of *all your black
MIDI key numbers*!
icps = (ipedal > 0? icps - (icps *
.1): icps + (icps * .1)
skip:
In the above, ".1" is the percentage of
the frequency you wish to add or subtract from your "basic pitch"
(12tet).
You may want to make some other kind of
pitch adjustment. For example you might put the low version (freq)
of the black key pitch in your table, then multiply it by some
factor if the pedal were up (gkpedal == 0):
icps = (ipedal > 0? icps + (icps *
.1): icps)
Or perhaps you want different groups of
"igoto" branches, where for example all F#'s modify in one way, all
G#'s in another.
Let me know how it works out for
you.

Dear Art, thanks for Your answer. I have

17 pitches per octave but (as You all know)I do have only 12
pitches per octave on the keyboard. I would like to allocate
the black key two pitches and I would like to change this with the
pressure of the una-corda-pedal (the left pedal). While pressing
the left pedal down, I would like to get a lower pitch, in the
other case, the higher pitch. But I have no idea, how to do it
with csound. So, I really need Your help! At least I hope, that
my idea of negotiating the limitation of 12 pitches per octave in

Yes, certainly. But tell us more
what you have in mind.
I assume your keyboard would be a
MIDI controller, correct?
An obvious choice would be a MIDI
foot controller input through the keyboard, or a MIDI footswitch
in conjunction with a foot controller or a portamento
pedal.
If you need specific pitches from
the pedal(s) - even from a standalone portamento pedal, Csound
could "round" the pedal to the nearest pitch, or indeed add a
rounded percentage to the current keyboard pitch.
There are many
possibilities.

Dear community,
I want to know, if it could
be possible, to get different pitches for e.g. fis and ges
during a live-midi performance.
What I desire, is to
influence the pitch by a controller, e.g. the left
piano-pedal.
I'm not speaking of pitch-bending, I really
mean an exact, clearly regognizable pitch, when You press a
key with od without this controller.
Is it
possible?

Re: Re: Re: Re: Re: different pitches during a live-midi performance
Dear community, my csd-file works now! I can hear sound, when I play, and the controller number 64 has an audible effect: if I don't use it, the pitches of note number 61, 63, 66 are higher, but, if I press it down, I can't hear these notes. I guess I have to define, what has to happen, if the left pedal is down.
There is one more thing, I don't understand: What exactly does the line icps = (ipedal > 0? icps - (icps * .9): icps + (icps * .1))
do? What do I have to do, if I want to change the pitch of a given note about e.g. 15 cents? Thanks again for Your patience, Stefan 2009/7/7 Art Hunkins <abhunkin@...>
Stefan,
Without declaring massign, instr1 receives all the
channel 1 data; instr2 all of the channel 2 data.
In this scenario, you'll need to set channel 2
either on the foot controller itself, or set controller 64 (or whichever) to
channel 2 on your keyboard. (The keyboard
otherwise outputs on channel 1.)
If this is not possible, or doesn't work, next
try:
Put:
gkpedal ctrl7 1, 64, 0, 1
as the first line of instr 1.
Restore your
massign 0, 1
Remove instr 2 and its note
If these don't work, I'd advise going to the
alternate method I suggested previously. (I'll also do some actual
experimentation of my own at that point.)

Dear Art, many thanks, again, for Your fast answer. There

foot-controller to channel two? Or is this already done with
gkpedal ctrl7 2, 64, 0, 1
2009/7/7 Art Hunkins <abhunkin@...>
Hello, Stefan,
Iain is correct (he always is, and you can totally
count on his advice regarding realtime). My bad. *Controller* 64 is the foot
controller/switch for MIDI.
Suggestions:
Delete line 14 *as well as 13*.
In instrument 2, substitute:
gkpedal ctrl7 2, 64, 0, 1
Then play your keyboard on channel 1, but put the foot
controller on channel 2. (Alternately, put the foot controller on any
channel except #1; number the instrument the same as the channel and give
the controller the same number also (e.g., gkpedal ctrl7 10 for channel
10).) This should send all keyboard data to instr 1, pedal data to instr
2.
Frankly, I've always had trouble getting insnum to
trigger notes, and never use it. If the above doesn't work, I'd try another
approach: use an always-on instrument 1 that handles *all* midi input; when
noteon's are received, it schedules events (through event or
schedkwhen) for instrument 2. Working at k-rate, it also handles pedal-data
(as in your i2).
All of my live performance works use this principle;
you can look at many .csd's at my website, arthunkins.com, if you'd like.
Let us know how you get on.

Some parts of this message have been removed.
Learn more about Nabble's security policy.
Hi Stefan,
Sorry - again my mistake. The line should
be:
icps = (ipedal > 0? icps - (icps * .1): icps + (icps * .1))
With the .9 value, the note is so low you can't hear it.
This line looks at the value of ipedal ( = up or
down), and adds .1 of the icps value to it if it's up, or subtracts .1
of its value if the pedal is down (ipedal > 0).
I should think you could adjust the fractional
value to equal 15 cents; probably the fractions need to be different.
Probably someone else on the list can give you an appropriate
formula.
Otherwise you'll probably need to arrange your
pitch conversion differently. (This could be more difficult because you're doing
the conversion via table lookup. Using a direct formula might turn out to be
more flexible in this case: e.g., do your fractions or cents with MIDI note
numbers, then convert to icps via formula.)

Without declaring massign, instr1 receives all
the channel 1 data; instr2 all of the channel 2 data.
In this scenario, you'll need to set channel 2
either on the foot controller itself, or set controller 64 (or whichever) to

If this is not possible, or doesn't work, next

Put:

channel 10).) This should send all keyboard data to instr 1, pedal data
to instr 2.
Frankly, I've always had trouble getting insnum to
trigger notes, and never use it. If the above doesn't work, I'd try
another approach: use an always-on instrument 1 that handles *all* midi
input; when noteon's are received, it schedules events (through
event or schedkwhen) for instrument 2. Working at k-rate, it also
handles pedal-data (as in your i2).
All of my live performance works use this
principle; you can look at many .csd's at my website, arthunkins.com, if you'd
like.
Let us know how you get on.

Hello, Stefan,
Here's what I'd try:
In header:
gkpedal init 0
and after your
massign:
massign 64, 2
(or whatever controller # your foot
pedal is, assign its data to instr 2. The massigns may be
tricky.)
You should be able to use any type
of foot pedal your MIDI keyboard will accept.
Make a completely new
instrument that receives MIDI data only on controller 64 (or
whichever # you choose):
instr 2
gkpedal ctrl7 1, 64, 0,
1
endin
The above instrument is always
receiving foot controller data.
In the score, add:
i2 0 3600
In your instr1, add (at
beginning):
ipedal = i(gkpedal)
and later (after icps
computed):
if imnn != 60 and imnn !=
62 and notnum ...... igoto skip ; this is a list of *all your
black MIDI key numbers*!
icps = (ipedal > 0? icps - (icps
* .1): icps + (icps * .1)
skip:
In the above, ".1" is the
percentage of the frequency you wish to add or subtract from
your "basic pitch" (12tet).
You may want to make some other
kind of pitch adjustment. For example you might put the low
version (freq) of the black key pitch in your table, then
multiply it by some factor if the pedal were up (gkpedal ==
0):
icps = (ipedal > 0? icps + (icps
* .1): icps)
Or perhaps you want different
groups of "igoto" branches, where for example all F#'s modify in
one way, all G#'s in another.
Let me know how it works out for
you.

[Csnd] Re: Re: different pitches during a live-midi

Dear Art, thanks for Your answer. I have
attached a small example to this mail. I use there a scale
with 17 pitches per octave but (as You all know)I do have only
12 pitches per octave on the keyboard. I would like to
allocate the black key two pitches and I would like to change
this with the pressure of the una-corda-pedal (the left
pedal). While pressing the left pedal down, I would like to
get a lower pitch, in the other case, the higher pitch. But
I have no idea, how to do it with csound. So, I really need
Your help! At least I hope, that my idea of negotiating the
limitation of 12 pitches per octave in this way will be
interesting for other musicians
to. Thanks Stefan :
2009/7/2 Art Hunkins <abhunkin@...>
Yes, certainly. But tell us
more what you have in mind.
I assume your keyboard would be
a MIDI controller, correct?
An obvious choice would be a
MIDI foot controller input through the keyboard, or a MIDI
footswitch in conjunction with a foot controller or a
portamento pedal.
If you need specific pitches
from the pedal(s) - even from a standalone portamento pedal,
Csound could "round" the pedal to the nearest pitch, or
indeed add a rounded percentage to the current keyboard
pitch.
There are many
possibilities.

[Csnd] different pitches during a live-midi
performance
Dear community,
I want to know, if it
could be possible, to get different pitches for e.g. fis
and ges during a live-midi performance.
What I desire,
is to influence the pitch by a controller, e.g. the left
piano-pedal.
I'm not speaking of pitch-bending, I
really mean an exact, clearly regognizable pitch, when You
press a key with od without this controller.
Is it
possible?
Insert movie times and more without leaving Hotmail®. See how.

Re: Re: Re: Re: Re: Re: Re: different pitches during a live-midi performance
Dear Art, thanks, it seems to work now. I didn't try it with chords now, but with one voice it works great. And I found something, which helps me, to concvert cents to fractions and vice versa: http://www.sengpielaudio.com/calculator-centsratio.htm
And, off course, scala is a great tool too. 2009/7/8 Art Hunkins <abhunkin@...>
Hi Stefan,
Sorry - again my mistake. The line should
be:
icps = (ipedal > 0? icps - (icps * .1): icps + (icps * .1))
With the .9 value, the note is so low you can't hear it.
This line looks at the value of ipedal ( = up or
down), and adds .1 of the icps value to it if it's up, or subtracts .1
of its value if the pedal is down (ipedal > 0).
I should think you could adjust the fractional
value to equal 15 cents; probably the fractions need to be different.
Probably someone else on the list can give you an appropriate
formula.
Otherwise you'll probably need to arrange your
pitch conversion differently. (This could be more difficult because you're doing
the conversion via table lookup. Using a direct formula might turn out to be
more flexible in this case: e.g., do your fractions or cents with MIDI note
numbers, then convert to icps via formula.)

Dear community, my csd-file works now! I can hear sound,
when I play, and the controller number 64 has an audible effect: if I don't
use it, the pitches of note number 61, 63, 66 are higher, but, if I press
it down, I can't hear these notes. I guess I have to define, what has to
happen, if the left pedal is down. There is one more thing, I don't
understand: What exactly does the line
icps = (ipedal > 0? icps - (icps * .9): icps + (icps *
.1))
do? What do I have to do, if I want to change the
pitch of a given note about e.g. 15 cents? Thanks again for Your
patience, Stefan
2009/7/7 Art Hunkins <abhunkin@...>
Stefan,
Without declaring massign, instr1 receives all
the channel 1 data; instr2 all of the channel 2 data.
In this scenario, you'll need to set channel 2
either on the foot controller itself, or set controller 64 (or whichever) to
channel 2 on your keyboard. (The keyboard
otherwise outputs on channel 1.)
If this is not possible, or doesn't work, next
try:
Put:
gkpedal ctrl7 1, 64, 0, 1
as the first line of instr 1.
Restore your
massign 0, 1
Remove instr 2 and its note
If these don't work, I'd advise going to the
alternate method I suggested previously. (I'll also do some actual
experimentation of my own at that point.)

Dear Art, many thanks, again, for Your fast

with
gkpedal ctrl7 2, 64, 0, 1

Hello, Stefan,
Iain is correct (he always is, and you can totally
count on his advice regarding realtime). My bad. *Controller* 64 is the
foot controller/switch for MIDI.
Suggestions:
Delete line 14 *as well as 13*.
In instrument 2, substitute:
gkpedal ctrl7 2, 64, 0, 1
Then play your keyboard on channel 1, but put the
foot controller on channel 2. (Alternately, put the foot controller on
any channel except #1; number the instrument the same as the channel and
give the controller the same number also (e.g., gkpedal ctrl7 10 for
channel 10).) This should send all keyboard data to instr 1, pedal data
to instr 2.
Frankly, I've always had trouble getting insnum to
trigger notes, and never use it. If the above doesn't work, I'd try

of foot pedal your MIDI keyboard will accept.
Make a completely new
instrument that receives MIDI data only on controller 64 (or
whichever # you choose):
instr 2
gkpedal ctrl7 1, 64, 0,
1
endin
The above instrument is always
receiving foot controller data.
In the score, add:
i2 0 3600
In your instr1, add (at
beginning):
ipedal = i(gkpedal)
and later (after icps
computed):
if imnn != 60 and imnn !=
62 and notnum ...... igoto skip ; this is a list of *all your
black MIDI key numbers*!
icps = (ipedal > 0? icps - (icps
* .1): icps + (icps * .1)
skip:
In the above, ".1" is the
percentage of the frequency you wish to add or subtract from
your "basic pitch" (12tet).
You may want to make some other
kind of pitch adjustment. For example you might put the low
version (freq) of the black key pitch in your table, then
multiply it by some factor if the pedal were up (gkpedal ==
0):
icps = (ipedal > 0? icps + (icps
* .1): icps)
Or perhaps you want different
groups of "igoto" branches, where for example all F#'s modify in
one way, all G#'s in another.
Let me know how it works out for
you.

Dear Art, thanks for Your answer. I have
attached a small example to this mail. I use there a scale
with 17 pitches per octave but (as You all know)I do have only
12 pitches per octave on the keyboard. I would like to
allocate the black key two pitches and I would like to change
this with the pressure of the una-corda-pedal (the left
pedal). While pressing the left pedal down, I would like to
get a lower pitch, in the other case, the higher pitch. But
I have no idea, how to do it with csound. So, I really need
Your help! At least I hope, that my idea of negotiating the
limitation of 12 pitches per octave in this way will be
interesting for other musicians
to. Thanks Stefan :

Yes, certainly. But tell us
more what you have in mind.
I assume your keyboard would be
a MIDI controller, correct?
An obvious choice would be a
MIDI foot controller input through the keyboard, or a MIDI
footswitch in conjunction with a foot controller or a
portamento pedal.
If you need specific pitches
from the pedal(s) - even from a standalone portamento pedal,
Csound could "round" the pedal to the nearest pitch, or
indeed add a rounded percentage to the current keyboard
pitch.
There are many
possibilities.

[Csnd] different pitches during a live-midi
performance
Dear community,
I want to know, if it
could be possible, to get different pitches for e.g. fis
and ges during a live-midi performance.
What I desire,
is to influence the pitch by a controller, e.g. the left
piano-pedal.
I'm not speaking of pitch-bending, I
really mean an exact, clearly regognizable pitch, when You
press a key with od without this controller.
Is it
possible?
Insert movie times and more without leaving Hotmail®. See how.

Hi Stefan,
Sorry - again my mistake. The line should
be:
icps = (ipedal > 0? icps - (icps * .1): icps + (icps * .1))
With the .9 value, the note is so low you can't hear it.
This line looks at the value of ipedal ( = up or
down), and adds .1 of the icps value to it if it's up, or subtracts .1
of its value if the pedal is down (ipedal > 0).
I should think you could adjust the fractional
value to equal 15 cents; probably the fractions need to be different.
Probably someone else on the list can give you an appropriate
formula.
Otherwise you'll probably need to arrange your
pitch conversion differently. (This could be more difficult because you're doing
the conversion via table lookup. Using a direct formula might turn out to be
more flexible in this case: e.g., do your fractions or cents with MIDI note
numbers, then convert to icps via formula.)

Dear community, my csd-file works now! I can hear sound,

Stefan,
Without declaring massign, instr1 receives all
the channel 1 data; instr2 all of the channel 2 data.
In this scenario, you'll need to set channel 2
either on the foot controller itself, or set controller 64 (or whichever) to
channel 2 on your keyboard. (The keyboard
otherwise outputs on channel 1.)
If this is not possible, or doesn't work, next
try:
Put:
gkpedal ctrl7 1, 64, 0, 1
as the first line of instr 1.
Restore your
massign 0, 1
Remove instr 2 and its note
If these don't work, I'd advise going to the
alternate method I suggested previously. (I'll also do some actual
experimentation of my own at that point.)

Hello, Stefan,
Iain is correct (he always is, and you can totally
count on his advice regarding realtime). My bad. *Controller* 64 is the
foot controller/switch for MIDI.
Suggestions:
Delete line 14 *as well as 13*.
In instrument 2, substitute:
gkpedal ctrl7 2, 64, 0, 1
Then play your keyboard on channel 1, but put the
foot controller on channel 2. (Alternately, put the foot controller on
any channel except #1; number the instrument the same as the channel and
give the controller the same number also (e.g., gkpedal ctrl7 10 for
channel 10).) This should send all keyboard data to instr 1, pedal data
to instr 2.
Frankly, I've always had trouble getting insnum to
trigger notes, and never use it. If the above doesn't work, I'd try
another approach: use an always-on instrument 1 that handles *all* midi
input; when noteon's are received, it schedules events (through
event or schedkwhen) for instrument 2. Working at k-rate, it also
handles pedal-data (as in your i2).
All of my live performance works use this
principle; you can look at many .csd's at my website, arthunkins.com, if you'd
like.
Let us know how you get on.

handles pedal-data (as in your i2).
All of my live performance works use this
principle; you can look at many .csd's at my website, arthunkins.com, if you'd
like.
Let us know how you get on.

Stefan,
Please tell us which lines are #30 and

If any German commentary is involved,
please translate for me; ich verstehe deutsch nicht so

I do see one error:
icps = (ipedal > 0? icps - (icps * .9):

(This may be the problem - or one of
them.)

Hello, Stefan,
Here's what I'd try:
In header:
gkpedal init 0
and after your
massign:
massign 64, 2
(or whatever controller # your foot
pedal is, assign its data to instr 2. The massigns may be
tricky.)
You should be able to use any type
of foot pedal your MIDI keyboard will accept.
Make a completely new
instrument that receives MIDI data only on controller 64 (or
whichever # you choose):
instr 2
gkpedal ctrl7 1, 64, 0,
1
endin
The above instrument is always
receiving foot controller data.
In the score, add:
i2 0 3600
In your instr1, add (at
beginning):
ipedal = i(gkpedal)
and later (after icps
computed):
if imnn != 60 and imnn !=
62 and notnum ...... igoto skip ; this is a list of *all your
black MIDI key numbers*!
icps = (ipedal > 0? icps - (icps
* .1): icps + (icps * .1)
skip:
In the above, ".1" is the
percentage of the frequency you wish to add or subtract from
your "basic pitch" (12tet).
You may want to make some other
kind of pitch adjustment. For example you might put the low
version (freq) of the black key pitch in your table, then
multiply it by some factor if the pedal were up (gkpedal ==
0):
icps = (ipedal > 0? icps + (icps
* .1): icps)
Or perhaps you want different
groups of "igoto" branches, where for example all F#'s modify in
one way, all G#'s in another.
Let me know how it works out for
you.

[Csnd] Re: Re: different pitches during a live-midi
performance
Dear Art, thanks for Your answer. I have
attached a small example to this mail. I use there a scale
with 17 pitches per octave but (as You all know)I do have only
12 pitches per octave on the keyboard. I would like to
allocate the black key two pitches and I would like to change
this with the pressure of the una-corda-pedal (the left
pedal). While pressing the left pedal down, I would like to
get a lower pitch, in the other case, the higher pitch. But
I have no idea, how to do it with csound. So, I really need
Your help! At least I hope, that my idea of negotiating the
limitation of 12 pitches per octave in this way will be
interesting for other musicians
to. Thanks Stefan :
2009/7/2 Art Hunkins <abhunkin@...>
Yes, certainly. But tell us
more what you have in mind.
I assume your keyboard would be
a MIDI controller, correct?
An obvious choice would be a
MIDI foot controller input through the keyboard, or a MIDI
footswitch in conjunction with a foot controller or a
portamento pedal.
If you need specific pitches
from the pedal(s) - even from a standalone portamento pedal,
Csound could "round" the pedal to the nearest pitch, or
indeed add a rounded percentage to the current keyboard
pitch.
There are many
possibilities.

[Csnd] different pitches during a live-midi
performance
Dear community,
I want to know, if it
could be possible, to get different pitches for e.g. fis
and ges during a live-midi performance.
What I desire,
is to influence the pitch by a controller, e.g. the left
piano-pedal.
I'm not speaking of pitch-bending, I
really mean an exact, clearly regognizable pitch, when You
press a key with od without this controller.
Is it
possible?
Insert movie times and more without leaving Hotmail®. See how.

Re: Re: Re: Re: Re: Re: Re: Re: different pitches during a live-midi performance
Hi Stefan -
I see the following problems in your code:
1. The condition
> if imnn != 56 && imnn != 68 && imnn !=80 igoto skip
will never become true. Probably you mean:
if imnn != 56 || imnn != 68 || imnn !=80 igoto skip
("or" instead of "and")
2. With the lines
> gkpedal ctrl7 1, 67, 0, 1 ; controller 67 is the left pedal
> ipedal = i(gkpedal)
you want to get "1" for "left pedal pressed" and "0" for "not
pressed". But this implies that gkpedal sends continually "1", and not
just once. Does it? Please insert the line
print ipedal
and watch the output.
Some tips:
- If you have problems, I won't use the -m0 flag, because it
suppresses some messages.
- I can't see any need for the statements
> gkpedal init 0
> ipch = 8.02
> iequal = 12
- Instead of icps*0.9760317607762247 you can write icps*cent(-42)
This was all related to your second question. Regarding the first, I
am sure it's possible, and there are many ways of doing it. One simple
way I can imagine, is, to switch between different function tables;
something like
if ipedal == 0 then
ift = 1
else
ift = 2
endif
and then later
icps table indx, ift
This depends on what you exactly want to do (how many function tables
you need, what your controller has as output, and so on). If you like,
tell us.
Hope that helps. Best regards -
joachim

..hm, maybe I'm missing something obvious but to me it looks like the
statement will be true in all cases where the imnn variable is not any
of the numbers 56, 68, 80

Totally correct. I was wrong. So this is not a part of Stefans problem.
