Dual ADSR Manual
4. RATE SWITCH
The rate switch selects between three different ranges for the attack, decay, and release
times. In FAST mode the maximum time for each stage is approximately 1 second. It is
approximately 10 seconds in MED mode, and 1 minute it SLOW mode.
5. A[TTACK]
This slider sets the duration of the envelope attack stage. This is the time it takes for the
envelope level to go from zero to the maximum level. The duration is nearly zero with the
slider at the bottom, and the longest when the slider is at the bottom. The length of the
longest setting is set with the RATE switch.
6. D[ECAY]
This slider sets the duration of the envelope decay stage. This is the time it takes for the
envelope level to go from the maximum to the sustain level. The length of the longest
setting is set with the RATE switch.
7. S[USTAIN]
This slider sets the level of the sustain stage. It is 0 V at the bottom and 5 V at the top.
8. R[ELEASE]
This slider sets the duration of the envelope release stage. This is the time it takes the
envelope to go from the sustain level back to 0 after the gate is released. The length of
the longest setting is set with the RATE switch.
9. LEVEL INDICATOR
The brightness of this LED indicates the level of the envelope.
Inputs & Outputs
A. GATE
While the gate input is high the envelope moves through its stages until it hits the sustain
stage. If at any time the gate goes low the envelope will enter the release stage.
For ADSR 2 this input is normalled to the input of ADSR 1 so that when no cable is
connected the GATE of ADSR 2, a gate signal at ADSR 1 can trigger both envelopes.
B. RETRIG
When a trigger is received at this input while the gate is high it resets the envelope back
to 0 and starts the attack phase again.
