Displaying continuous MIDI data

[Charles Gran]

I want csound to display values for things like sliders.  It would be
great if it only did so only when the sliders change.  Something like
midi-ox on windows if you know it.  Any ideas?

You can use OSC to connect your sliders to csound. OSCListen return
value is either 0 or 1; it is 1 only if a new message was received. By
testing for this you know when to display the slider value.

hope this helps

You could ouput data to the console using printk2:

<CsoundSynthesizer>

<CsOptions>
-odac -M0
</CsOptions>

<CsInstruments>

sr    =    44100

printk2 kCC1
endin
   
</CsInstruments>

<CsScore>

or to an FL widget:

<CsoundSynthesizer>

<CsOptions>
-odac -Ma

Lauren found her dream laptop. Find the PC that’s right for you.

Charles,

What is your platform, and/or GUI (or commandline)?

I'm in Windows, and work with MIDI sliders all the time - and routinely
display controller values.

On the commandline, printk2 prints a new value only when the value changes.
(And in any case, you can save the old value, compare the next kvalue with
it and print it only if changed.)

I use Lettuce as my GUI; through chnexport its easy to display slider values
on-screen.

With FLTK there was a mechanism attached to FLslider for displaying its
value in an on-screen box as well.

I'm sort of going back-and-forth between a PC and a big imac, but
mostly I've been using XP with the command-line.

I'm putting together a real-time piece with a clarinet that will be
processed.  I'm not sure what platform he will run it on, but I'm
guessing a PC laptop.
