The goal was to fix the issues that existed with the previous prototypes. Whether this is now the case I'll not comment about. I have been disappointed a few times before after getting excited about new PCBs.

So another round of prototypes is now going to get manufactured where I made some drastic changes that I left out of previous prototypes:

In The Mean Time: Software Refactoring

While I wait for the new PCBs I will continue working on the next major update of the software. The code that handles MIDI and controls the OPL3 chips will be refactored to allow for some cool new tricks:
