Assembled - Stop Switch - 10 ohms between U1-14 and U2-1 when off, more like 1M ohms when off - Single Step - 12V through 10k Ohms to U-1-14, more like 1M when off - Glide attenuator (B10k) (join two left pins from below Clock rate goes down when resistance goes up, opposite to expectation. C1 is too small; need more than 100k to get 1:1 between schematic and PCB, no warnings Add splits and labels to get 1:1 between schematic and PCB, .../Unseen Servant/Unseen Servant.kicad_pro | 85 cd18ed43dc Added hard sync (to a clock/gate/trigger input) Quantizer Interfaces to digital components and interconnects between middle and bottom boards. Final work on PCB Added hard sync to schematic, laid out PCB with on-board components Add correct footprints to fireball Add correct footprints to fireball Merge pull request synth_mages/MK_SEQ#2 Added schmancy pcb for v2 front panel and Pin 1, vertical PCB mount, https://www.neutrik.com/en/product/nc3fav1 A Series, 3 pole female receptacle, grounding: ground contact to mating connector shell and front panel, vertical PCB mount, https://www.neutrik.com/en/product/ncj6fa-v Combo I series, 3 pole female XLR receptacle, grounding: mating connector shell and front panel, vertical PCB mount, https://www.neutrik.com/en/product/ncj10fi-v-0 Combo I series, 3 pole male XLR receptacle, grounding: mating connector shell and front panel, horizontal PCB mount, https://www.neutrik.com/en/product/nc3faah2 AA Series, 3 pole male XLR receptacle, grounding: separate ground contact to mating connector shell and front panel: 9.8mm (alpha pots sliders: 3mm above panel, ample thunkicons: probably too short without extra spacers, use mini toggle pushbuttons: ample space above 11.75mm (existing 1p12t rotaries, use 11.25mm holes to PCB edge 4.9399999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 15-pin D-Sub connector, straight/vertical, THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 7.699999999999999mm, distance of mounting holes to PCB edge 8.2mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 37-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 7.699999999999999mm mounting-holes-distance 47.1mm mounting-hole-offset 47.1mm 25-pin D-Sub connector horizontal angled 90deg THT female pitch 2.77x2.84mm pin-PCB-offset 14.56mm mounting-holes-distance 25mm mounting-hole-offset 25mm 9-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 14.56mm mounting-holes-distance 63.5mm mounting-hole-offset 63.5mm 37-pin D-Sub connector horizontal angled 90deg THT female pitch 2.29x1.98mm pin-PCB-offset 9.4mm 15-pin D-Sub connector, solder-cups edge-mounted, male, x-pin-pitch 2.77mm, distance of mounting holes 63.5mm, distance of mounting holes to PCB edge 8.2mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 62-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 14.56mm, distance of mounting holes 63.5mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 25-pin D-Sub connector, horizontal/angled.
