description / manual
ADSR can be triggered with a Gate signal and will output the envelope with a range of 0V to +8V on the regular output jack and 0V to -8V on the inverted output jack. ​
The envelope may be re-triggered using the RTRG input as long as the Gate on the Gate Input is high. Â
ADSR has three different Length Modes from Slow over Moderate to Fast. The envelope can be very short (20uS) up to very long (110s) making it a useful tool for percussion like sounds and evolving soundscapes. The Moderate Mode is the best option for regular synth sounds. ​
The LED between the A (Attack) and D (Decay) potentiometer indicates the current state of the envelope.
