I implemented the Velocity Limiting feature so when I received notes that were louder than I wanted, the system would reduce them. I proved it was working by printing a message when I used the capped velocity and the modified command.
I copied the Velocity Limiting code to implement Pitch limiting. This time, I had a lower limit, and I had to modify the Note Off commands, so it was four times as much code as the previous feature.
I added MIDI functionality to my 68-key keyboard by soldering a wire to the internal controller’s pin and connecting a wire from a nearby filtering capacitor for power. I constructed a tester with two LEDs to indicate correct wiring, ensuring the MIDI connection worked properly. After confirming it functioned as intended, I closed up the piano.
When I connected my MIDI piano to the controller, it struggled to respond reliably, often missing note commands due to timing signals. Switching to a Rock Band keytar reduced interference. I created a Velocity Floor in TcMenu to minimize my instrument volume, but a synthesizer would get any desired velocity.
I imported scale and chord names from a previous project and tried to print them when I changed on the microcontroller, but I got errors that I thought were a menu wraparound feature. I researched the issue and discovered it was because I had too few items in my array, but I found a method for printing names to the serial port instead.
Sarah and I had Richard Davis on the show to talk about cosplay. I have made a few costumes in my time, and I think that a sewing machine is one of the most versatile power tools.
Anniversary 0!
I got married on Friday! We scheduled our wedding for Pi Day 2025, so it will be easy to remember future anniversary dates. Naturally, the desert of honor was pie.
The rest of the summary posts have been arranged by date.
