BackStorage; decipher key matrix, work out either MC or dumb resistor array to output correct volts for each stage? * TBD, needs testing; but if LEDs are possible, this should be possible, too * Manual trigger See manual step (featuring debouncing!), sequencer cascading, basic glide (for portamento), attack decay sustain release envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md ## GitHub repository https://github.com/holmesrichards/precadsr Submodules Latest commits for file Synth_Manuals/The MIDI Manufacturers Association - 1995 - MIDI 1.0 Detailed Specification.pdf Normal file Unescape Hardware/Panel/precadsr_panel_al/precadsr_panel_al.pretty/precadsr-panel-holes.kicad_mod Normal file View File 3D Printing/Cases/Eurorack Modular Case/EuroRack_Case_24.png Executable file View File 3D Printing/Pot_Knobs/Pot3.STL Executable file View File Hardware/Panel/precadsr_panel.svg Normal file Unescape 2x Sockets, all three pins need wires: glide in (sleeve and normal both GND 6x Sockets, 2pin: - all step switches (all go to same bus 2x Pushbutton switches, all 2pin: - step - reset in - CV out, with probably +12v gates.
