Odp: [sdiy] Level Headed

[Roman]

That only depends on what the release level is.
Don't know about Putney, but mine are 0V. So
adjusting envelope depth
doesn't change filter's rest frequency. Envelope's
ability to go negative
and positive in one cycle is another story tho.
I must agree, for simple ADSR envelopes it's wierd
to have them bipolar.
But they are so boring anyway ;)
