When the feedback of delay two goes back to the
front of the line before the filters, it is coming in at the same place an
external input sound would come in. Both are run through the VCA which comes
after the Filter (see diagram). The VCA Envelope is triggered by a keypress. So
when you release the key, the sound is gated by the VCA Envelope. Such
gating is slowed by the VCA Envelope Release of course.The parameter for VCA
Level allows the sound to go on and on. This works for external input so the
Evolver can be used as an effect. Turning VCA Level up should also give you the
endless loop you are looking for without a keyhold or long release time (i.e.
turning up VCA Level negates the affectiveness of the VCA
Envelope).

Hi folks,
I'm slowly getting through all of the great features on my PEK and have
come across something strange. In all of the documentation and diagrams for
signal flow of the evolver voice, it shows that the feedback 2 for delay
sends the delayed signal back to the filter section, where it should follow
through the VCA and then through the delay again. Mine doesn't. I have a
basic patch of plain saw waves going through an open filter and no envelopes
or modulation (VCA level = 0, sustain = 100), and then through delay 1, with
time set at 125 and amount at 70. This exhibits a signal, with repeat.
Turning up feedback 2 should give me multiple repeats, but it does not -
just the same one note and one repeat. The feedback 1 works as it should
(when turned up, more repeats occur). Feedback 2 seems not to do anything,
EXCEPT when I'm holding a note down on the keyboard, or when the release
time of the VCA is turned up. Then, it does its job, but only until the note
is released. What is up with this? Shouldn't it output multiple repeats
similar to feedback 1, but affected by filtering, etc.? Maybe something else
is supposed to be on, but I can't figure it out.
Thanks,
Mark
