... But it is still possible to specify up to 16 different PB, so different for each channel, in one MIDI clip. In case notes are coming on different channels and Synth is able to work with that (for example, TTS-1), that can have desired effect.
I have just tested the following: TTS-1, Channel 1 and Channel 2 are "Piano 1". One note on channel 1, another on channel 2, with 2 "Wheel" envelopes in different directions. So, one note is bended up and another down, simultaneously!
I think that a MIDI guitar is the (
worst-tracking) solution here. Set the Basic Channel, then use it and the next 5 MIDI Channels as a 6-part controller with independent pitch bends. But back in the keyboard controller realm ...
KMI's
QuNexus controller features an interesting take on that process: Channel Rotation. Each note played in a sequence is switched to the next MIDI Channel. When all notes are released, it rotates back to Channel 1. Polyphonic pitchbend, channel pressure, or key aftertouch for per-note control. Of course, the receiving synth must be set to Omni (like most of the CW Instruments by default).
At one point, I explored using MFX like
TenCrazy's Note Rotator or Channel Switch plugins to cobble together that type of effect. At the time, not all of the MFX plugins were converted to 64-bit (they are now). In the meantime, I programmed a
MIDI Solutions Event Processor (Plus) to allow any of my keyboard controllers to accomplish this before it gets to "the box".
You can do it with portamento in legato mode. That's how the bending logo sounds are typically done.
I have a polyphonic portamento script floating out there from RGC. It's an easily-modifiable .sfz file that would work in Dimension Pro, Rapture, etc. Even PSYN II had Bend options for bending some notes while holding others (uni-directional).
For that matter, multi-Channel pitchbend is possible in those later model synths across Elements; ticking Multimbral Mode. Not an automatic, because you'd still have to send over multiple channels. But that could be contained in a single track.
