Pin for op amp Fix floating pin for op amp in schmidt inverter mode, maybe both 7808 and hex inverter trigger are unnecessary? Alternative: Midi -> CV Alternative: CV from something else VCF MK's Diode Ladder VCF Kassutronic's KS-20 VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some example modules schematic start, and some example modules Envelope/Envelope.kicad_pcb | 2 | 1nF | Film capacitor | | U2 | 1 | LM358 | Low-Power, Dual Operational Amplifiers, DIP-14/SOIC-14"/> 972e45fb785c49166ca9391405caa86c3c4b7992 replaces FIREBALL mask/etch with silkscreen Latest commits for file Panels/FireballSpell_Large.webp Images/PXL_20210831_000922493.jpg Normal file Unescape Hardware/PCB/precadsr/Kosmo_panel.pretty/fastestenv_LED_Hole.kicad_mod Normal file Unescape Envelope/Envelope.kicad_pro Normal file Unescape Hardware/PCB/precadsr/Kosmo_panel.pretty/Kosmo_Pot_Hole_NPTH.kicad_mod Normal file View File Hardware/PCB/precadsr_aux_Gerbers/precadsr-Edge_Cuts.gbr Normal file View File Panels/Font files/futura medium bt.ttf differ Binary files a/Schematics/Fireball_VCO.pdf and b/Schematics/Fireball_VCO.pdf differ b11a8d3187 Go to file 56529bef3a Updates from real TL0x4s 5cacbfea2e Add polygon calculation for wing plates 3e868f13c4 Go to file 007cc05932 Checkpoint after tweaking footprints some more.
