Re: [xl7] polyphony question

That explains why some of my patches don't produce any sound at all.

They have eaten all the polyphony BEFORE i ever pressed a key. :)

  Actually, it's *2* keys, because a chorused voice with a 12th order
  filter uses 4 voices, not 3.

  "2 voices" x "2 12th order penalty" x "4 layers" x "3 linked" = 48
  voices per note!

  And no, they can't share the filter because one osc is panned left and
  the other right, thus needing separate filter paths to keep the signals
  separate.
