BackAndFor Delay. That goes forward, backwards or alternates BackAndFor. There’s 4 delay lines to select your direction and your octave pitching, along with level and delay amount. And a filter to take the harshness of the higher octave settings.
Aux selects pages. Knobs changes things on pages.
Low C,D,E,F select reverb direction for the 4 delay lines. Follow the arrows on screen.
High C,D,E,F select octave pitch for the 4 delay lines. Follow the numbers on screen.
This is pretty amazing, thank you!
