Support Kassutronic's KS-20 VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some supporting components. ~$6 in parts, needing only one tl074 and support Kassutronic's KS-20 VCA MK's VCA Everything by Hagiwo (quantizer, filters, noisemakers, etc) MIDI-to-CV, either over USB or directly over 5-pin DIN (with optoisolator) What we build next? Pretty confident we do know we need a diode to U2-3 Clock In - diode to U2-3 - Clock rate (B100k) (not sure yet which 2 pins LED diameter 3.0mm z-position of LED center 9.0mm 2 pins LED, Round, FlatTop, diameter 5.0mm, 2 pins, http://www.kingbright.com/attachments/file/psearch/000/00/00/L-13GD(Ver.11B).pdf LED Round FlatTop Rectangular size 5.0x2.0mm^2 z-position of LED center 1.6mm, 2 pins LED diameter 3.0mm z-position of LED center 9.0mm 2 pins diameter 1.8mm size 1.8x2.4mm^2 z-position of LED center 3.0mm 2 pins LED diameter 3.0mm z-position of LED center 2.0mm 2 pins LED diameter 5.0mm Tantal Electrolytic Capacitor CP, Radial series, Radial, pin pitch=27.50mm, , length*width=29*9.6mm^2, Capacitor, https://en.tdk.eu/inf/20/20/db/fc_2009/MKT_B32560_564.pdf C Rect series Radial pin pitch 10.00mm length 11.5mm width 5mm Capacitor C, Radial series, Radial, pin pitch=12.20mm, , length*width=25.4*14.7mm^2, Vishay, TJ5, http://www.vishay.com/docs/34079/tj.pdf L_Toroid Horizontal series Radial pin pitch 25.4mm length 16mm diameter 7.5mm C, Axial series, Axial, Horizontal, pin pitch=49mm, , length*diameter=42.5*20mm^2, Electrolytic Capacitor CP, Axial series, Axial, Horizontal, pin pitch=43mm, , length*diameter=37*20mm^2, Electrolytic Capacitor, , http://www.vishay.com/docs/28342/058059pll-si.pdf CP Radial series Radial pin pitch 37.50mm length 41.5mm width 15mm Capacitor C, Rect series, Radial, pin pitch=37.50mm, , length*width=41.5*31mm^2, Capacitor, http://www.wima.com/EN/WIMA_MKS_4.pdf C Rect series Radial pin pitch 5.08mm size 81.3x11.2mm^2 drill 1.3mm pad 2.6mm Terminal Block 4Ucon ItemNo. 10701, vertical (cable from top), 14 pins, single row (from Kicad 4.0.7), script generated Surface mounted socket strip SMD 2x38 1.00mm double row surface-mounted straight pin header, 1x13, 2.54mm pitch, DIN 41651 / IEC 60603-13, double rows Through hole straight socket strip, 2x17, 1.27mm pitch, double rows Through hole angled pin header SMD 1x25 2.54mm single row male, vertical entry Harwin LTek Connector, 7 pins, pitch 5mm, size 72.3x14mm^2, drill diamater 1.3mm, pad diameter 2.6mm, see http://www.metz-connect.com/de/system/files/productfiles/Datenblatt_311751_RT027xxHBLC_OFF-022814U.pdf, script-generated using.
