Full Description
View Full DescriptionControls
- A: This is the Attack time control. When the envelope is triggered, a control voltage is put out at the two Output sockets, rising to maximum in the time set by this control
- D: This is the Decay time control. This is the time it takes for the control voltage output to fall to the level set by the sustain control (S)
- S: This is the Sustain time control. This is the steady-state voltage level after the decay phase. This level remains the same until the gate is closed
- R: This is the Release time control. As soon as the gate signal finishes, the control voltage falls to zero at a rate set by this control
- ADSR Control: Envelope state indication LED.
- Time Range: Three-position range switch. It allows you to select your desired time range for the envelope:
- H: High. This time range can go up to minutes
- M: Medium. This is the standard mid-range for envelope lengths
- L: Low. Down to less than 100 microseconds
Inputs/Outputs
- Gate: Input for Gate voltage. This is a switched socket, normalled to the INT.GATE circuit on the system bus. A gate signal on this circuit will trigger the ADSR, even without an input to the socket. If however, you connect a gate signal to the socket, then the connection with the system bus is broken and the ADSR is triggered from this socket instead. The normalling can be removed by taking out the small red jumper in the top right-hand corner of the PCB
- Retrig: Input for re-trigger voltage. This can be connected to sources such as the output of an LFO. This means that whilst the gate is open, the envelope will re-trigger any time it senses a pulse from the LFO
- Output (Below Retrig.): Responds to a Gate signal by putting out the voltage envelope set by the ADSR controls. Whenever the ADSR is triggered, this output carries the envelope voltage as defined by the ADSR parameters
- Output (Above Inverse Output): Responds to a Gate signal by putting out the voltage envelope set by the ADSR controls. Whenever the ADSR is triggered, this output carries the envelope voltage as defined by the ADSR parameters
- Inverse Output: Responds to a Gate signal by putting out an inversion of the voltage envelope set by the ADSR controls. It carries exactly the same voltage envelope as the regular outputs, but inverted, with negative instead of positive voltages
