honostly, this probably cost the same as a trigger finger or an mpd 24. I haven’t calculated the total cost, but the circuit board is $75, the buttons are $2 each, and the faders were $14 each i think, the pots and knobs were probably less than a buck each. So total cost is at least $150 not including some tools I didn’t already have and wire and stuff I did already have.
This was definitely more for fun than for economic reasons.
