Factory Sound #112

[chysn]

When I heard this sound, I was all, "Whaaat?!"

It's a simple triangle sound when the key is pressed down and held. And then, when the key is released, a chime-like sound comes in. It's a really neat trick for a synth without reverse envelopes.

The filter envelope amount is set to 0, so the filter envelope doesn't affect the filter. Instead, the filter envelope controls Osc A PW via the Poly-Mod section at 100%. Osc A's PW is set to 50%. The filter envelope is then set to fast attack and decay, and the sustain level is set so that the Osc A becomes inaudible (due to PW) during sustain.

Then, when the release stage returns the envelope to 0, the Osc A PW dives back to 50%, and is audible again. Result... a sound that plays when the note is released! The filter envelope release basically controls the attack rate of the Osc A sound.

It is a pretty cool sound, indeed.

This patch was an eyeopener for me too when I first worked out what was going on. I took that trick with forcing the oscillator into silence into some of my own patches where I’ve simulated a shimmer reverb (same note coming in later like an octave-up echo). When using PU2 mode, it means you can still have a 2-oscillator sound with the shimmer.

What is PU2 mode?

What is PU2 mode?

Polyphonic unison with two voices per note. Obviously works much better with 10 voices and presents a compelling argument for getting the P10 or installing the expansion card.

Thanks for this post - it's great to learn more about programming techniques!

If you've ever had one of those moments on a poly where you didn't realize you had Local On and the DAW was sending back double notes and went "holy crap that sounds amazing.. hey where did my polyphony go" ... that's what PU2 is basically, with a little detuning added in for good measure.  But if you're into chords and pads, the expansion board is definitely worth considering for this feature alone (not to mention splits/stacks).

Thanks!

I might wind up with the expansion some day.
