Ladder VCF Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an arduino nano (other options probably fine), two 74HC595 shift registers (accidentally a pile in my collection) and the hazards therein programming MCs to be able to add hard sync input. CV in implement a DC offset via non-inverting op-amp. A CV in to pause the clock Add CV in to pause the clock oscillilator an external CV-to-pulse-rate module? Is this even useful? - Seven-segment display. Can be done, but requires a trigger-sized pulse on input. - But could also go to same bus 2x Pushbutton switches, all 2pin: - all step switches (all go to same bus 2x Pushbutton switches, all 2pin: - Glide attenuator (B10k) (join two left pins from below Clock rate (B100k) (not sure yet which 2 pins diameter 3.0mm z-position of LED center 1.6mm, 2 pins diameter 3.0mm z-position of LED center 1.0mm 2 pins Ceramic Resomator/Filter Murata TPSKA, http://cdn-reichelt.de/documents/datenblatt/B400/SFECV-107.pdf, 7.9x3.8mm^2 package SMD Crystal Seiko Epson SG-8002CE https://support.epson.biz/td/api/doc_check.php?mode=dl⟨=en&Parts=SG-8002DC, 3.2x2.5mm^2 package SMD Crystal Oscillator Seiko Epson SG-8002LB https://support.epson.biz/td/api/doc_check.php?mode=dl⟨=en&Parts=SG-8002DC, hand-soldering, 14.0x8.7mm^2 package SMD Crystal MicroCrystal MS3V-T1R 5.2mm length 1.4mm diameter http://www.microcrystal.com/images/_Product-Documentation/03_TF_metal_Packages/01_Datasheet/MS3V-T1R.pdf SMD Crystal EuroQuartz MT series http://cdn-reichelt.de/documents/datenblatt/B400/MT.pdf, 3.2x2.5mm^2 package SMD Crystal Oscillator Seiko Epson SG-3030CM package SMD Crystal MicroCrystal CC4V-T1A series http://cdn-reichelt.de/documents/datenblatt/B400/CC4V-T1A.pdf, hand-soldering, 5.0x1.9mm^2 package SMD Crystal Oscillator Seiko Epson SG-8002LB https://support.epson.biz/td/api/doc_check.php?mode=dl⟨=en&Parts=SG-8002DC, hand-soldering, 10.5x5.0mm^2 package SMD Crystal Oscillator Seiko Epson SG-8002JA https://support.epson.biz/td/api/doc_check.php?mode=dl⟨=en&Parts=SG-8002DC, hand-soldering, 10.5x5.0mm^2 package SMD Crystal Oscillator Seiko Epson MC-306 https://support.epson.biz/td/api/doc_check.php?dl=brief_MC-306_en.pdf, hand-soldering, 9.6x4.1mm^2 package SMD Crystal SERIES SMD2520/4 http://www.newxtal.com/UploadFiles/Images/2012-11-12-09-29-09-776.pdf, 2.5x2.0mm^2 package SMD Crystal G8, hand-soldering, 3.2x1.5mm^2 package SMD Crystal SERIES SMD2520/2 http://www.icbase.com/File/PDF/HKC/HKC00061008.pdf, 5.0x3.2mm^2 package SMD Crystal EuroQuartz MQ2 series http://cdn-reichelt.de/documents/datenblatt/B400/MQ.pdf, 7.0x5.0mm^2 package Miniature Crystal Clock Oscillator TXCO Fordahl DFA S3-KS/LS/US, http://www.iqdfrequencyproducts.com/products/details/iqxo-70-11-30.pdf, hand-soldering, 7.0x5.0mm^2.
