So this is my project Syncussion. Instead of trying to fix the old case I decided to just make my own from scratch and here are the results.
Includes:
1x SY-1 Drum synth with MSW MIDI interface
1x 1/4" TRS to DIN5 MIDI Cable
2x 1/4" TRS to TS splitter
2x 1/4" TRS to 3.5mm Splitter
1s PSU
2x Pearl Drum triggers with new speakers and heads
1x Pear Drum Trigger Stand
1x Pearl Syncussion Stand
1x Original SY carcass with old I/O board
