All the experimentation with the drum machine led me to believe that it would be able to communicate with the Electronic Wind Chimes effortlessly. This was foolish. When the EWC was being constructed to accept MIDI input, all the testing was done with the first version feeding it a steady stream of note 60 on and off. Receiving these was possible just by printing the incoming data.

For some reason, notes coming from the drum machine were always wrong. Not only were they wrong, but they were repeatably wrong. It may have been possible to accept the errors and code for the actual signals, but at the bit level, it seemed like a lot of data was missing, and no amount of parity or hack programming would restore it reliably. This was going to take more investigation.
