DECAY:
This Control sets the Decay time of the EGR from 1 msec to 10 seconds.
SUSTAIN:
This is a level control for the sustained part of the envelope.
RELEASE:
This is the time for the envelope to return to zero, from 1 msec to 10 seconds.
AMOUNT TO FILTER:
For the filter envelope, this is the control that adjusts the amount that the filter
envelope signal modulates the filter. It has both positive and negative values. If it is
set to a positive value, say +2, The envelope will add to the Cutoff control. If it is a
negative value, say –2, the envelope will subtract from the Cutoff control.
KEYBOARD/ ON/EXTERNAL:
The Envelopes are started by a gate signal. The envelopes will sustain as long as
a gate signal is still present. When the gate is off, the release of the envelope
happens. The Switch labeled Keyboard/ On/External selects whether the envelopes
are triggered from the keyboard, on, or from an external trigger source. When
Keyboard triggering is selected, the envelopes are triggered from the keyboard
gate signal. When the switch is set for On/ external, the Envelopes are on if nothing is
plugged into the external trigger input. In this case the envelopes sustain at the level
determined by the sustain controls. This is useful for keeping the envelopes
sustaining without holding a key down when you want to process an external audio
signal through the filters with out using the keyboard, or create drones. When
On/external is selected and a footswitch or external gate signal is applied to the
envelope gate input on the back panel, the envelopes are triggered from that
input.
RATE CONTROL INPUT:
The Control Input on the back labeled RATE is a CV input for external control of
the Voyager’s Envelope time constants. The Input accepts -5 to 5 Volts, or an
expression pedal like the EP-1. An expression pedal or a positive voltage applied
here decreases the attack, decay, and release times from where the front panel is
set for both the filter and the volume EGRs. A negative voltage will increase the
attack, decay, and release times from where the front panel is set for both the filter
and the volume EGRs (figure 22).
