I spent the day struggling with EEPROM storage. TcMenu had it built in, but I could not get it to work. I poured over the documentation and examples, but the best I could do was accidentally reboot. I can try again with low-level programming.
I missed a step in the TcMenu documentation for selecting EEPROM settings while regenerating code. On the Arduino side, I could not get anything working until I called EEPROM.commit() after saving to write data to non-volatile memory. While some variables are not fully functional, the EEPROM issue is mostly resolved and ready for further work.
I programmed the octave shifting to have a low octave next to a high octave. If I were playing something like a church organ, I could hold a deep note, while fluttering a few higher ones, but I would only need a two-octave keyboard, like my keytar.
I drafted some pseudo-code to outline melody looping. I am excited to see how useful this is and whether I should build another device to perform this function.
I created a function to assign each octave of a played note to its corresponding channel, which I refined by debugging with print statements. Although I initially struggled with some arithmetic errors and instrument changes limited to channel 0, I reorganized the code to allow unique instruments to play on separate channels and at ideal pitch ranges.
Matt Knowles, Steph, Sarah, and I discussed The Goonies. We loved the nostalgia, talked about the problematic parts, and I wore a Hawaiian shirt with plaid pants.
The rest of the summary posts have been arranged by date.
