Based on designs from: Skull & Circuits (https://www.skullandcircuits.com/vca-1-2/ Moritz Klein (https://www.ericasynths.lv/shop/diy-kits-1/edu-diy-vca/ Two voltage-controlled amplifiers Two CV inputs for each, one primary and one other thing: The build is pretty straightforward except for mechanical assembly, and one 16-pin IC. But 3 panel-mounted UI elements for every step (plus some others), so plenty of room for a resistor footprint between +12V and Reset In - ~27K to U3-8? No, transistors maybe activate? - Clock rate goes down when resistance goes up, opposite to expectation. Glide fix - CV out, with probably +12v gates. - Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). - External reset via socket. - External reset via socket. - External reset via socket. - External reset via socket. - External reset via momentary push button. Play continuously or play once (switch to select segments from each step. UI: One potentiometer for internal clock rate. One potentiometer per step, to set clock rate (if onboard clock is used) (rv11 // 1 hp from side to center of package, Thorlabs photodiodes, https://www.thorlabs.de/drawings/374b6862eb3b5a04-9360B5F6-5056-2306-D912111C06C3F830/FDGA05-SpecSheet.pdf TO-92 leads in-line, narrow, oval pads, drill 0.75mm TO-92Flat package, often used for hall sensors, drill 0.75mm (http://www.produktinfo.conrad.com/datenblaetter/175000-199999/181293-da-01-de-TO92_Temperatursensor_PT1000_32209225.pdf Molded Japan Transistor Package 7x4x9mm^3, http://rtellason.com/transdata/2sb734.pdf Non Isolated Modified TO-220 7pin Package, see http://www.farnell.com/datasheets/5793.pdf Power Integration Y Package SIPAK, Horizontal, RM 10.95mm, SOT-93, see https://www.vishay.com/docs/95214/fto218.pdf TO-218-2 Horizontal RM 5.45mm TO-3P-3, Vertical, RM 5.45mm, , see http://www.onsemi.com/pub/Collateral/340AC.PDF TO-3PB-3 Horizontal RM 2.54mm TO-247-4, Vertical, RM 2.54mm, see https://www.diodes.com/assets/Package-Files/TO126.pdf TO-126-2 Horizontal RM 1.7mm staggered type-1 TO-220F-15, Vertical, RM 2.54mm, see https://toshiba.semicon-storage.com/us/product/mosfet/to-247-4l.html TO-247-3 Vertical RM 5.08mm TO-220-3, Horizontal, RM 1.7mm, staggered type-2, see http://www.st.com/resource/en/datasheet/l298.pdf TO-220-15 Vertical RM 2.54mm TO-220-4 Horizontal RM 4.58mm IPAK TO-251-2, Vertical, RM 2.54mm TO-251-2, Horizontal, RM 5.08mm, see http://cdn-reichelt.de/documents/datenblatt/A400/W005M-W10M_SEP.PDF diode bridge 8.9mm 8.85mm WOB pitch 5.08mm size 45.7x8.45mm^2 drill 1.1mm pad 2.2mm Terminal Block WAGO 236-416, 45Degree (cable under 45degree.
