Voice allocation in the same manner as you'd find on some classic old polys, like Oberheim 4/8 voice etc..

I really enjoy this approach to polyphony, considerably more flexible that the usual method. Can have subtle difference between voices, or even completely different architecture. Also gives more control over which components of your patch are poly, and which remain mono.

The Block itself is very straight forwards. 4 x pitch and gate outputs. Panel controls for selecting MIDI channel, pitch bend range, and unison.

I'm sure more features could be incorporated... Komplete Kontrol colours for example. Bare in mind, you can pair this up with the standard Note In module, if you want mod wheel, after touch etc.

Poly Blocks sound amazing!!!

Edit: Unison mode sending unwanted events. Now fixed, also added unison spread and glide.

When I hook the pitch/gate into a simple oscillator I get only weird klick sounds. Anyone else with the same problem?

Great block David!!! thanks for sharing. Are there any plans to add velocity for each voice?

Brilliant! Thank you David. I'm using this with Internal Control connections and hiding panels to gang the voices.

Amazing! One small suggestion; a voice select mode would be cool. So incremental (1-4, repeat), reset (1-4 polyphonic but always start at 1 when re-triggered) or random. I've been creating some cool patches in Reason where various voices are longer/shorter, up/down an octave or a fifth and they're selected randomly as you play. Just a suggestion, otherwise I'll have to figure out how to do it myself! Question is, am I bright enough ;)

Very nice, but indeed, as Josue said, an 8 voice version would be nice!

This is definitely the best way to do Poly...having different voicings can lead to some very creative patches! Excellent job David

It seems a few of us are trying to work around the monophonic limitations. Well done.

Excellent! After reading so many comments about the 'lack of polyphony', I felt similarly inclined to build a block to demonstrate this classic trick. You've done a much better job - I'm excited to explore it in depth. And I hope this extinguishes anyone's doubt about the potential of this environment. ;) Cheers and thank you!
