I integrated an Arduino library that measures clock jitter to generate random numbers. The process could be faster, but it does a masterful job of seeding the controller's rand() function. I ran the program and took a screenshot to show that the program starts with unique numbers each time, but before the library, they were identical.
mode2() played multiple instruments simultaneously by utilizing fifteen MIDI channels. I moved the pitch controllers from encoders at the bottom to potentiometers at the top. I created an array to hold the relevant data, like channel, note, velocity, probability, and offset. I also figured out a tidy method to sustain channel notes until the next one played, even if other channels were active, significantly improving the cohesion between different instruments.
Three instruments playing in mode2
I planned and programmed mode2(), but I should have paid more attention to a few things in the first round. Some of my notes hung, and every channel played a Grand Piano (MIDI instrument #0). I fixed the problems and recorded a video demonstrating all the current modes.
I repaired some minor problems with the then moved onto mode3(), which will be percussion. I spent significant time planning it on paper and implementing it in code. The machine played some notes but it was not the loop I expected. I printed the table, which looked correct, but it bears investigating.
Percussion table
I forgot to use a counter that would step through the tracks, so I implemented one, and the notes played well. I cleaned up other issues with the code, but mostly ways to stop sounds from hanging. I wrote a list of percussion instruments I want to avoid appearing in prandomly generated arrangements and wrote a check to play drums instead.

Entropy library ensuring different starting points

I powered up the equalizer with an external battery todampen the signal enough that an iPhone could record a clip. I also tested the power running from the battery to the Arduino, which checked out. I extracted the audio and uploaded it to GitHub to embed it into this page.
