Not directly csound, but hoping to appeal to the knowledge of those
who've used software synths, like Zebra 2. I'm playing around with the
Zebra 2 demo, and turns out that one can't set pitch bend differently
for each channel; all notes (no matter what channel they belong to)
respond to a pitch bend message sent to any channel. This kind of
shoots down the idea of microtuning each note of a chord independently
without resorting to one VST instance for every note.

Anyone know if this is generally true of software synths, especially
analog models?

Hello Johann,
   it depends on the programming of the synth. it's easily possible to have 
controllers sent on one channel only work on that channel. Where pitch bend is 
concerned; Only think of the simplest MIDI player. If the solo instrument uses 
pitch bend, the rest of "the band" continues normally.
   Kind regards
          Julien

Not sure I follow.

Let me phrase it like this. The midi spec indicates that pitch bend
messages have a channel. So I would think the designers of the spec
intend pitch bend to affect only notes on that channel and leave other
notes undisturbed.

With Zebra 2, I had several notes playing, all on different channels.
I send pitch bend messages on various channels. Always, all the notes
bent the same. This even happened when I sent a pitch bend message on
a channel with no sounding notes.

So now I'm thinking, the Zebra 2 design doesn't follow the midi spec
strictly. The designer seems to have skimped on that particular issue.

And that leads me to wonder if this aspect of the midi spec is usually
followed or usually ignored, particularly by analog software synths.

I'm not sure if you are saying I could wire up a patch in Zebra 2 that
allows independent pitch bend.

  I'm not familiar with Zebra 2 (and probably need to brush up on my 
MIDI), but I'm wondering, do you have it set to MIDI Omni mode? Because 
that will send incoming messages to all channels, iirc.

Interesting... I can't find any midi settings at all in Zebra 2.3.

hueeviz is a Processing applet that plays an mp3 of my 2007 Csound song Huee and creates a simple visualization. Huee is a xenharmonic piece in 10-TET writtten with Csound and blue, and was one of my first Csound compositions.
