To clone: submodules avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals PCB layout: make power connection traces larger; MK uses (and runs about $100 on ebay); Korg lists Trade-Up Music as a sequence of 8 voltages controllable by individual knobs. MK's 5-step sequencer, expanded to 8 (or 10?) Bergman's 10-step sequencer (up to 10) https://www.eddybergman.com/2022/04/8-step-sequencer-v2.html very similar core to MK's, but using fewer diodes (substituting LEDs in sliders, lit for each Contribution on the footprint.
