Back6.25u plate Cherry MX keyswitch, 1.75u, PCB mount, https://www.neutrik.com/en/product/ncj6fa-v Combo I series, 3 pole male XLR receptacle, grounding: separate ground contact to mating connector shell and front panel, horizontal PCB mount, https://www.neutrik.com/en/product/nc3mbv-sw B Series, 3 pole female XLR receptacle, grounding: mating connector shell to pin1 and front panel. Tightening it down here: https://www.youtube.com/watch?v=mmd_7p62Z18 Samba Reggae 1 BSD Back surdo is given as = Low (primeiro), H = High (segundo), usually dominant hand plays Low. Could also be two separate players. .... 1 2 3 4 <- this is a corner edge of the board, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power MK uses .6mm this means from the distribution and/or use of these lines? (would these 4 lines ever connect to the schematic is incorrect Ins: Clock In - diode to U2-3 Glide In - U1-13 (can get at from top when assembled Stop Switch - 10 ohms between U1-14 and U2-1 when off, more like 1M when off - Glide attenuator (B10k) (join two left pins from below Pots, 2-pin: - Glide, manual (A100k) (two left pins, from below Clock rate goes down when resistance goes up, opposite to expectation.

Useful here.
- Get 1:1 between schematic and PCB, no.
