Single-step button (SW13) isn't producing a high enough voltage to trigger a second sequencer's run, which then re-triggers the first. CV in to pause the sequence. Seven-segment display. Can be done, but requires a trigger-sized pulse on input. - Portamento (aka slew rate controller aka glide). - Knob version fairly simple. - CV Range - Once/Cont When in Cont mode shorts Casc Out - 1K to TP5 - Gate out (could normal to TP10, optional 2x Toggle Switches, 2pin: - all step switches (all go to same bus 2x Pushbutton switches, all 2pin: - step - reset Pots, 3-pin: Glide attenuator (B10k) (join two left pins from below Clock rate (B100k) (not sure yet which 2 pins LED_Rectangular, Rectangular, Rectangular size 5.0x5.0mm^2, 2 pins, pitch 7.5mm, size 54.8x14mm^2, drill diamater 1.15mm, pad diameter 2.6mm, see http://www.mouser.com/ds/2/324/ItemDetail_1935161-922578.pdf, script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_RND THT terminal block Metz Connect Type175_RT02705HBLC, 5 pins, pitch 3.5mm, size 25.2x7mm^2, drill diamater 1.2mm, pad diameter 2mm, outer diameter 3mm, size source Multi-Contact FLEXI-E 0.75 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-106-02-xxx-DV-BE-LC, 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 Mini-Fit Sr. Power Connectors, 105313-xx05, 5 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 Mini-Fit Sr. Power Connectors, old mpn/engineering number: 1-770186-x, 4 Pins (http://www.farnell.com/datasheets/2157639.pdf), generated with kicad-footprint-generator Molex Mini-Fit Jr. Power Connectors, 42819-52XX, 5 Pins per row (http://www.molex.com/pdm_docs/sd/530470610_sd.pdf), generated with kicad-footprint-generator Molex MicroClasp Wire-to-Board System, 55932-0510, with PCB cutout, light-direction upwards, see https://www.everlight.com/file/ProductFile/ITR1201SR10AR-TR.pdf reflective opto couple photo coupler IR Receiver Vishay TSOP-xxxx MINIMOLD IR.
