Is there any way in z3ta+ 2.1 to have the LFO sync with a keypress?  I'm trying to make the classic Baba O Riley sound, and I think it's done by having a square LFO modulating amplitude & the trills come from having the LFO start with each keypress.

Hello Joe,
Check out the attached image, I think this is the basic patch functionality you need in the mod matrix to create that effect. You can always change parameters to match your sound, but this is a basic mod matrix and patch for that sound.
hope that helps!
 

Thanks, but that doesn't really do what I'm looking for.  I'm actually hoping I can make the LFO start with each keypress, so if I press 2 keys 1/32 of a note apart from each other and the LFO's are sync'ed to 1/16 timing, then I'd hear essentially a 1/32 trill between them.  On Korgs (and probably many other synths), this is called "key sync".

Hi Joe - try this:

Set up LFO5 with a square wave.  FWIW, LFO5 and 6 are "per-voice" (PV), (versus "all-voice" (AV)), so for every key you hit on your musical keyboard, that voice will get it's own LFO modulator.  Set the LFO5 Phase to "0 degrees".  Now map LFO5 to "Oscillator Pitch" in the Mod Matrix, and I think you'll have what you're looking for.  Let me know.  Hope this helps.
