Use the buttons left/right to change one of the four parameters:
- Left joystick: Left -, right +: Attack time
- Left buttons: B -,A +: Decay time (note: buttons +, - are inverted)
- Right joystick: Left -, right +: Sustain level
- Right buttons: A -,B +: Release time
Note: anything left decrements, anything right increments
This is the same program as my second wave display
