100644 Schematics/Luthers_Perfboard.pdf From dd8c61c34faaeb27b8a193b7a0410df7bb5b6b87 Mon Sep 17 00:00:00 2001 Subject: [PATCH] More work finding space for well-aligned, well-printed numbers // step (manual) -- this is the two keybeds in storage; decipher key matrix, work out either MC or dumb resistor array to output correct volts for each key. Build a MIDI->CV module ** Hagiwo's cheap arduino version and https://github.com/elkayem/midi2cv which it was received.
