Updated this version of Hexperiment to:
1) not crash when the buttons are mashed 2) have the code laid out in order closer to how latest firmware is laid out. Things I am planning to do next: 1) restore ability to transpose up/down 2) put back the brightness/arpeggio-speed/wheel-sensitivity options from before 3) get MPE mode working reliably on Logic Pro and Pianoteq (two popular synths that cover the Mac and Windows landscape) Pipe dreams: 4) try to build out the sequencer functionality 5) get file system working (read/write tuning systems, scales, preferences, beat patterns) 6) code cleanup -- mostly, move stuff into headers so navigating is easier Meanwhile if you want me to focus on something in particular I am happy to contribute to the cause however you want. This has been such a great project and I hope this expands the market for the HexBoard to microtonal folks, as there's definitely a need and a willingness to pay !
