Non-functional Tremolos

All three Tremolos are non-functional in my implementation of jOrgan.

My computer is an Intel Celeron CPU 2.40GHz with 1GB of RAM, running
Windows  XP Pro (32 bit). A single Creative SoundBlaster Audigy card is
in PCI slot 1  with driver version 5.12.1.512 dated 7/8/2005. Creative
SoundFont Bank  Manager ver.3.21.00 tells me that eorg105tremtest.sf2 is
loaded in Banks 000,  020, and 021. I recently moved from jOrgan 3.7 to
3.8-beta2. I'm playing  the English Organ eorg_e104_v3.4SB.disposition
as customized for my  DIY-midified 2MP Allen TC-4 organ using MIDI
hardware from Roman Sowa  (Poland). All three Tremolos (Solo, Swell,
Choir) are set Locking - True,  with the following typical messages:

Activate   Equal 193  Equal 124  Equal 0
Deactivate Equal 193  Equal 124  Equal 0
     [Note: Equal 193 or 194 or 195, as the case may be]

Engaged    Set 176    Set 99     Set 127  Soundfont NPRN identifier.
Engaged    Set 176    Set 98     Set 20   Trem amplitude depth.
Engaged    Set 176    Set 38     Set 12   Set trem amplitude depth.
Engaged    Set 176    Set 99     Set 127  Soundfont NPRN identifier.
Engaged    Set 176    Set 98     Set 17   LFO (trem) frequency.
Engaged    Set 176    Set 38     Set 2    Set trem pitch depth.
Engaged    Set 176    Set 99     Set 127  Soundfont NPRN identifier.
Engaged    Set 176    Set 98     Set 1    Trem pitch depth controller.
Engaged    Set 176    Set 38     Set 50   Set trem frequency.

Disengaged Set 176    Set 99     Set 127  Soundfont NPRN identifier.
Disengaged Set 176    Set 98     Set 20   Trem amplitude depth.
Disengaged Set 176    Set 38     Set 0    Reset trem amplitude depth off.
Disengaged Set 176    Set 99     Set 127  Soundfont NPRN identifier.
Disengaged Set 176    Set 98     Set 17   LFO (trem) frequency.
Disengaged Set 176    Set 38     Set 0    Reset trem pitch depth off.
Disengaged Set 176    Set 99     Set 127  Soundfont NPRN identifier.
Disengaged Set 176    Set 98     Set 1    Trem pitch depth controller.
Disengaged Set 176    Set 38     Set 0    Reset trem frequency off.

[Note: The amplitude depth, pitch depth, and frequency settings vary
slightly  among the three Tremolos, but are mostly disposition defaults.]

jOrgan flags no Problems, and all the speaking stops, couplers and
combination pistons function, but none of the three Tremolos is
functional.  Does anyone know how to help me get them working?

Carl,

The NRPN values that you are setting in your "Enagaged" messages, and
resetting in your "Disengaged" message are only tailoring the LFO
parameters.  They are not really turning LFO modulation on and off.  LFO
Modulation is actually turned on (127) and off (0) with Continuous
Controller 1.  However, once LFO Modulation HAS been turned on, the
resetting of the NRPN parameters in your "Disengaged" set will
effectively set the LFO amplitude to 0 -- which for all intents will
make the LFO Modulation "appear" to be OFF.

What you need to do is add an "Engaged" message to turn ON LFO Modulation:

Engaged    Set 176     Set 1      Set 127    Turn on LFO Modulation

and then you should turn it off with a "Disengaged" message:

Disengaged Set 176     Set 1      Set 0      Trun off LFO Modulation

CLWells,

Ok, I incorporated the suggested two lines in each of the three Tremolos (Swell, Choir, Solo), but the only stop that now produces a Tremolo is the Stopped Flute 8 on the Swell. No other stops are affected, so something additional must be wrong. Since my organ has only two manuals, I access the Choir and Solo manuals through Choir-Swell and Solo-Swell couplers, but I don't think that should prevent the Choir and Solo Tremolos from affecting their respective ranks. Any more suggestions?

Carl


What you need to do is add an "Engaged" message to turn ON LFO Modulation:
Engaged    Set 176     Set 1      Set 127    Turn on LFO Modulation
and then you should turn it off with a "Disengaged" message:
Disengaged Set 176     Set 1      Set 0      Turn off LFO Modulation

Carl,  while in Construct Mode, Click on each division's tremolo and under
References make sure that all the Ranks in that division that you want to be
affected by the tremolo are listed.  That is probably what the reason is
that you are only hearing the Stopped Flute 8.   You are right that the
tremolo only affects those stops of the division which are referenced to it
in that division.  Also make sure that everything references the Console
Name.  Any of these items that are missing will cause the tremolo to not
function.

Success!
With the help of John Beach, I finally have the Tremolos functioning in Bruce Miles' English Organ.

Earlier today I read in Bill Skees' "A Beginners Guide to jOrgan" volume 1, that "Your sound cards must not only be Creative Labs Sound Blaster or Sound Blaster Audigy sound cards, but...they can only be certain models. The official jOrgan website lists the cards at

http://jorgan.sourceforge.net/sound:hardware:creative ...."

Because my Creative SoundBlaster Audigy SE-VARPak model SB0570 was not in Bill's list, I began to doubt whether the English Organ tremolos would ever work.

But after reading John's latest message (below), I was emboldened to delete the 18 default lines of Engaged and Disengaged messages from each of the three Tremolos, replacing them with the two lines he suggested. So there are now only four message lines for each Tremolo. After saving the changed eorg_e104_v3.4SB.disposition file and reloading it, I was delighted to find the Tremolos are now working. The only exceptions that I know of are the Fanfare Trumpet 8, the Tuba 8, and the Cornet V, all reed ranks on the Solo manual. My conclusion is that these three ranks do not have tremmed samples in the eorg105tremtest.sf2 file loaded into my SoundBlaster sound card.

Nothing succeeds like success!

Zero turns it completely off. If you have it set to 127 it will produce a Tremulant but it magnifies the effect disproportionately. I hope this is helpful.

Instead of your having to send a MIDI message, use Set 176 Set 1 Set 50 (or whatever rate you like).

Not all SoundBlasters are Creative - some are incompatible OEMs

even though they look alike on the outside.

All four cards must be the precise, same cards, since the software is just
different enough that if you mix the cards, nada - zip - zed - nuthin'.

I learned the hard way, as when I later purchased two cards to match my

The software driver that runs all cards wants to see matching SoundBlasters,

When I purchased four matching cards, they shook hands well.

Some parts of this message have been removed. Learn more about Nabble's security policy.
Yes, but one could still use Fluidsynth with them and the sound quality and polyphony  from Fluidsynth, according to some, is superior to the Creative Sound.  Finding the ideal settings in Fluidsynth requires some trial and error but it does work well.  And, yes, you can't argue with Success.

A further question about Trems

In the Christie disposition I am using a Soundfont file in Fluidsynth.  
I am using the "sub 50" function to control the Trems.
I have noticed that the Trem change only takes effect when you either
change note or release and replay the current note.

Is this the only way this can function?

How can I configure the Trem function to change the current playing note?

Thank you
Regards
Rick

1."I have noticed that the Trem change only takes effect when you either

2. Is this the only way this can function?

3. How can I configure the Trem function to change the current playing
note?"

I infer that you are talking about the fact that, if while holding a
key/chord you turn on the tremulant, it does not start....Sven will have to
confirm this, but I think this involves the idea of a time-relative switch
message  interrupting a frequency/volume state and the keys, being switches
in the MIDI protocol, require a "re-switching" in order for the change to
take place.
If/since that is the case, that is the only way that can take place, unless
with the program change (i.e., Stopped Flute 8 NT, no trem to Stopped Flute
8 Trem) message involving tremmed samples or the tremmed state of the preset
in the soundfont, it is not the same as the switch concept as explained
above.

Concerning 3 above, if by "to change the current playing note" you mean
alter it by frequency or volume, in the soundfont that is done in the
modulation envelope section of Vienna Soundfont Studio.  The frequency is
set and then the pitch or volume (Tremolo or Vibrato difference).
Otherwise, the trem function is effectuated in the two manners described,
either by the Trem switch Engaged/Disengaged or by the Program Change
message to change Preset from untremmed preset to tremmed preset.

This is one of the ways that SAMPLED trems are handled.  When you turn
the Trem on, the sample is switched in the MIDI channel using the MIDI
ProgChg command to a patch number which is 50 less than the patch number
of the un-tremmed sample.

> I have noticed that the Trem change only takes effect when you either
> change note or release and replay the current note.

Yes.  When the MIDI ProgChg command is used to change the sample in the
MIDI channel, you will not hear the effect of this voice change until
the NEXT newly played note.  Any notes being held (playing) at the time
that the trem is turned on and off will NOT change to the new voice
while still being held/playing.

>
> Is this the only way this can function?

Yes.

>

You would have to change the trem feature from using SAMPLED trems to
the Low Frequency Oscillator (LFO) "artificial" trem method.  The LFO
trem may be switched on and off with the MIDI CC 1 command.  This method
of engaging and disengaging the LFO trem will indeed affect currently
playing notes like you want -- but in order to use this method, you will
have to give up the sampled trems.

Hi Lynn

Thank you for the clear answers and description of options.  I will do
some experimenting.

What is your preference on handling Trem?

Given the trade-off between sampled trems and no-immediate-effect for
held notes, versus LFO trems and immediate-effect for held notes, my
preference is for sampled trems.

If you are using GSO3 as your sound rendering engine (instead of
Creative sound cards or Fluidsynth) you can configure GSO3 to trigger
the trem samples with the CC 1 command rather than having to use the
ProgChg command.  However, I'm not sure this fixes the
"no-immediate-effect for held notes" problem.

Try this latter question on Joe Hardy (VTPO forum).  If anyone can
answer this definitively, he can.

Just out of interest, I notice that Miditzer seems to deal with this.  It is using Patch Change control with Tremmed and Un-tremmed samples through Fluidsynth.  The Trem change takes effect at the time of switching.  It does actually sound like it re-triggers the note its self (almost unnoticed) for the change to take effect.  This re-triggering of the note seems to be done in a clever way that does not re-trigger a percussive voice if it is registered on at the same time.

Rick et al,

The NRPN method of of configuring trems does allow 'while notes are
held'switching It has been around for some years, is well documented in the
jOrgan Notes (para 31ii ) and is used in both the English and Village organs
on my website. But the problems are it will only work in Creative sound
cards and not all of them. And accurate setting is not very easy.
For these reasons the 'patch change' method is preferred for theatre organ
, but this suffers from the 'can't switch while notes are held, problem
which is of some importance for theatre organ.

There is another method which can be configured in jOrgan, allows 'notes-on'
switching and works in Fluidsynth which I have working. When I have a
complete  functional disposition I will let you know . So - - - watch this
space.

Cheers

Bruce

Thanks Bruce

I look forward to your new findings when they are ready.
