Thx for your tips guys)
The reasoning behind having only one knob is so that i can place X filters on X channels and use them in a more improvisational/ergonomic setting… (Saves controller real estate , better in a live scenario, fun, etcetcetc;))
(Knob 1-8 on controller → filter on track 1-8)
one knob controls LO/HI combi with a neutral centerpoint.
- and a reset button;)
