- regeneration is the duration
- delay knob is the density.

ac DELAY MODE up to 400 ms of delay time in delay mode with a stereo ping pong effect.
There are 4 echo modes: 50 / 100 / 200 / 400 ms

Some delay parameters can be adjusted:
- delay: sets the delay time
- regeneration: sets the number of echoes.
