Retrigger The threshold at which the envelope detector resets such that it can trigger again in
fractions of full scale where 0dB is full scale. This value is only useful when it is below the
value of Trigger.
Env Rate The envelope detector decay rate which can be used to prevent false triggering. When the
signal envelope falls below the retrigger level, the
fi lter can be triggered again when the
signal rises above the trigger level. Since the input signal can fl uctuate rapidly, it is
necessary to adjust the rate at which the signal envelope can fall to the retrigger level. The
rate is provided in decibels per second (dB/s).
Rel Rate The downward slew rate of the triggered envelope generator. The rate is provided in
decibels per second (dB/s).
Smth Rat e Smooths the output of the envelope generator. Smoothing slows down the envelope
follower and can dominate the release rate if set lower rate than this parameter. You can
use the smoothing rate to lengthen the attack of the generated envelope which would
otherwise have an instant attack. The rate is provided in decibels per second (dB/s).
