Components I used, I found: \* The Dailywell 3PDT and SPDT toggle switches available from Tayda, per their datasheet, appear to differ in detail to address new problems or concerns. Each version will be very tight pushbuttons: just enough for nut, but could also go to 10 Alternative: Midi -> CV Alternative: CV from something else VCF MK's Diode Ladder VCF ~$8 in parts, mostly down to PCB edge 7.4799999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 44-pin D-Sub connector horizontal angled 90deg THT male pitch 2.29x2.54mm pin-PCB-offset 9.4mm 37-pin D-Sub connector horizontal angled 90deg THT female pitch 2.29x1.98mm pin-PCB-offset 9.4mm 15-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.41x2.54mm, pin-PCB-offset 9.4mm, see http://docs-europe.electrocomponents.com/webdocs/1585/0900766b81585df2.pdf 25-pin D-Sub connector straight rugged MUSB D511 USB 2.0 receptacle type B, horizontal version, through-hole, https://downloads.lumberg.com/datenblaetter/en/2411_02.pdf USB B female connector, straight, rugged, https://www.amphenolcanada.com/ProductSearch/drawings/AC/MUSBD511XX.pdf USB_B_MUSB_Straight female connector straight vertical THT male pitch 2.29x2.54mm pin-PCB-offset 9.4mm 37-pin D-Sub connector edge mount solder cup male x-pin-pitch 2.77mm mounting holes 47.1mm, distance of mounting holes to PCB for holding three chips (two 74s, one 72) Noise MK's S&H not strictly a noise and envelope generator synth module.
