from various sources.

behaviour of the envelope.

tes a short pulse that can be retriggered after
the Hold Time setting. You can set the
trigger sensitivity by using the Threshold control.

In this mode, keep Attack close to the minimum to
let the envelope the time to rise.
• Gate Trigger (middle setting) generates a continous
state that lasts as long as Hold Time. You can set the
trigger sensitivity by using the Threshold control.
Hold Time
can lenghten the trigger time, if necessary.
• Envelope Follower (downmost setting) means, that
the filter envelope is driven by the input signal itself.
Threshold
and Hold Time have no influence at all.
