The GMSN! Pure ADSR is used to create CV envelope, which can be patched into other modules to control pitch, filter cutoff and volume. These are either triggered externally or manually via the trigger button.
There are three envelope modes to choose from:
- ADSR – Once triggered the envelope goes through all 4 stages: Attack, Decay, Sustain & Release
- AR – The envelope will go straight into the Release phase as soon as Attack is completed. Great for drum synthesis
- Trap Mode – This is a looping trapezoidal envelope with 4 stages: Attack, On, Release, Off. This can be retriggered externally or via the trigger button and can be used to create looping LFO shapes.
