Again, the way the level of the input signal changes will likely effect how
you will want to set the Release time. If you want the modulation changes
to track a quickly changing input signal you will likely want to have faster
Release (and Attack) times. If you want the Width and rate mod to change
more smoothly you can increase the Release (and/or Attack) times
accordingly so they are slower than the rate of change in the level of the
incoming signal.
Remember that the Threshold setting interacts with and has a direct affect
on when the Rate and Width modulation will begin to occur, how much of
the modulation will occur (based on how far above the Threshold setting
the signal goes). How the Attack and Release times will be set will most
often depend on the type of response you want and how long the signal
stays above the threshold setting.
Env. Mode
The Envelope mode switch affects the way the underlying envelope
follower, Threshold, Attack and Release responds and works together.
There are two settings: ‘Env’ and ‘Gate.
With the “Env” setting, all the controls work as described. The Threshold
setting determines when the Rate and Width mod takes affect, how far
above the Threshold setting affects how much of the mod is implemented
and how long the signal stays above the Threshold determines how the
Attack and Release will be used. This could be considered the ‘standard’
mode.
When the switch is set to “Gate” the envelope response changes as follows.
The amount of Rate or Width mod is no longer dependent on how far above
the Threshold setting the signal goes and instead responds more like an
On/Off switch (or Gate). As soon as the input signal goes above the
Threshold setting the Rate and /or Width mod will be driven to its maximum
