Supply Eurorack voltage. 0 0 Dual VCA, based roughly on Moritz Klein's work, but with buffering between (some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a notice placed by the cone indents can be fixed elsewhere fix/merge_issues Start of LM13700 version to see why Use THT electrolytics, finish SMT layout, try on quentin font for size Schematics/Dual_VCA_with_cv2_OTA.diy Normal file View File Panels/futura medium condensed bt.ttf' ## Current draw ### Current draw PCB layout: front, back How to apply smooth = 20; // How much horizontal space needed for left-hand and right-hand sub-panels left_panel_width = 12.5*3 + tolerance*4; // column from edge plus hole radius // mounting holes 25mm, distance of mounting holes 25mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 26-pin D-Sub connector edge mount solder cup male x-pin-pitch 2.77mm mounting holes 33.3mm, distance of mounting holes 63.5mm, distance of mounting holes 63.5mm, distance of mounting holes 63.5mm, distance of mounting holes to PCB edge 11.32mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 15-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.77x2.84mm, pin-PCB-offset 14.56mm, distance of mounting holes to PCB edge 4.9399999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 37-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.29x1.98mm, distance of mounting holes with circular drills, http://www.alps.com/prod/info/E/HTML/Encoder/Incremental/EC11/EC11E15204A3.html Alps rotary encoder, PEC12R, with switch, https://www.cui.com/product/resource/sj1-353xng.pdf TRS 3.5mm, horizontal, through-hole, with switch, vertical shaft, http://www.alps.com/prod/info/E/HTML/Encoder/Incremental/EC12E/EC12E1240405.html Alps rotary encoder, EC12E...
