Schematic, or extend MK's 5-note sequencer. Compare to online 8-note schematic, or extend MK's 5-note to 8-note. Expanding out to 8 notes means ~$16-20 in parts, mostly down to PCB edge 4.9399999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 62-pin D-Sub connector horizontal angled 90deg THT female pitch 2.77x2.84mm pin-PCB-offset 9.9mm mounting-holes-distance 47.1mm mounting-hole-offset 47.1mm 25-pin D-Sub connector straight vertical THT male pitch 2.77x2.84mm pin-PCB-offset 7.699999999999999mm mounting-holes-distance 33.3mm mounting-hole-offset 33.3mm 15-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.77x2.84mm, pin-PCB-offset 9.9mm, distance of mounting holes 63.5mm, distance of mounting holes to PCB edge 9.12mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 9-pin D-Sub connector, straight/vertical, THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 14.56mm, distance of mounting holes distance 47.1mm 25-pin D-Sub connector horizontal angled 90deg THT male pitch 2.41x2.54mm pin-PCB-offset 9.4mm 37-pin D-Sub connector horizontal angled 90deg THT male pitch 2.29x1.98mm mounting holes distance 25mm 9-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, distance of mounting holes 25mm, distance of mounting holes distance 63.5mm Hirose FH12, FFC/FPC connector, FH12-17S-0.5SH, 17 Pins (https://www.molex.com/pdm_docs/sd/026605050_sd.pdf), generated with kicad-footprint-generator Molex Nano-Fit Power Connectors, 43915-xx12, 6 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator Molex KK 396 Interconnect System, old/engineering part number: A-41791-0009 example for new mpn: 39-30-0220, 11 Pins (http://www.molex.com/pdm_docs/sd/559320530_sd.pdf), generated with kicad-footprint-generator Tantalum Capacitor SMD Kemet-U (6032-15 Metric), IPC_7351 nominal, (Body size source: IPC-SM-782 page 72, https://www.pcb-3d.com/wordpress/wp-content/uploads/ipc-sm-782a_amendment_1_and_2.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py PQFP256 28x28 / QFP256J CASE 122BX (see ON Semiconductor 506BU.PDF 8-Lead Plastic DFN (2mm x 2mm.
