Replacement SSK board for Yamaha CS15 synthesizer
This repo contains the Arduino sketch and Eagle .brd/.sch files for Old Crow's Yamaha CS15 "SSK board" replacement key assigner project. The project is meant to be open source/open hardware with NON-COMMERCIAL use granted by the author. All board logos and other identifying marks are to be left intact, otherwise enjoy.
Notes: the board is sized to work as a drop-in replacement with the mounting holes and headers positioned in the expected locations. I might make a more compact general use version for 61 keys. This version allow the use of one of two opto types in the gate circuit: Sharp PC817 or PC829. I had a bunch of the latter which is why they were made an option.
