polyphony problem with fffb~

Hello, I'm trying to sort out a polyphony problem, but I'm fresh out of ideas. If anyone can help, I'd really appreciate it, cause I've been trying to solve this for a week or so to no avail.

There are two problems that I'm experiencing:

1. Any time a voice receives a pitch that was different from the last pitch it received, it "ramps" to the new pitch. I'm not sure if the problem has something to do with this: https://cycling74.com/forums/index.php?t=msg&th=20222&rid=0&S=b2ede72c451a527ebe5381116b43362c but I've already tried sending the fffb~ a signal of 0 for 100ms between when the voice finishes and when thispoly~ gets sent "0, mute 1". Nothing changed. :(

2. The first time a voice is used, all I hear is an impulse (but no filters decaying). This is a modal synthesizer, so it works by modelling the modes and then sending fffb~ an impulse.

The synth is attached.

Thanks,
Anthony
