I simplified the scaling code by replacing a while() loop with a modulus and learned to calculate a note's octave using simple division. I wrote a function to play a pseudo-random note in the same octave upon key press, managing this through integer math and a 128-byte array. Now that the scales are programmed, most of the heavy lifting for the project is complete.

Function to pseud-randomly play a note in its octave

I programmed the first mode of automatic chords. When I play any note, the additional notes of the selected chord will play simultaneously. I can still sustain and release like usual.

The chord plays as soon as I press a key

I added a second chord mode. When I press one key, it plays the note as usual, but if I press a second, it ignores the new pitch and plays the selected chord. I can fumble about clumsily and only ever play notes or chords.

A note plays, then the chord follows if I press a second key

I spent the day adding MIDI over Bluetooth, but I only got as far as supporting noteOn and noteOff. They were the most critical, but I may have to investigate each command and parse its function to work wirelessly. Control Surface compiled correctly when other libraries failed, but it did not have the option to send arbitrary commands. I checked my reliability with MIDI Scope on my phone.

I encountered errors when transmitting Wireless Note Off signals due to sending them too quickly, so I refined my function to ensure it only sent the correct Note Off signal. I also created a function to convert any regular MIDI signal to the appropriate Control Surface command, but I found that several General MIDI ranges were ineffective, limiting me to sending only notes. The controller's memory usage was at 95%, but it dropped to 30% when I recompiled without the Control Surface.

On Critical Affection, Sarah and I discussed AppleTV's For All Mankind, season 1. Sarah enjoyed the empowered women, and I appreciated the hard sci-fi.
