MIDI, POLIPHONIC AND ADDITIVE SYNTHESIS

hi list,
you will find two patches here attached.

i’m tring to build a midi poliphonic patch with
additive synthesis… now i’m using only one
sinewave, just to try the amplitude control…

i have a big problem… i realized that
when i move the number box of the amplitude…
it is applied only to ONE NOTE of the poliphony…

my goal is to make additive synthesis while i play
poliphonic keboards…

do you have some suggestion?????
thanks

You don’t need to use the “target” message, [poly~] does this automatically for MIDI input data if you prepend it with “midinote”. Look into the reference pages for [poly~] to learn more. You might also want to look at the “steal” message for voice stealing. Good luck.

First of all, please save your patches as small as possible, or select them and do Edit >> Copy Compressed. They show up at 24″ on my 15″ laptop and I can’t find the scroll bars.

To answer one question, if you send [target 0] to [poly~] then it will send your amplitude function to all 16 instances of [poly~]. Secondly, if you pack the notein with a [prepend midinote] then it will keep the noteon/noteoff events sorted out so that you can have polyphonic noteoffs. I wasn’t sure how you were working the modulation in there, because I didn’t have your targetbeep4 patch. Let me know if this makes some sense to you. I didn’t know what the [ctlin 7 1] part was supposed to do–I’m assuming it just didn’t translate because you didn’t pack your targetbeep4 poly~ patch.
