In the afternoon, I compared solenoids with different strokes.
Unfortunately, the long-stroke solenoid did not deliver the expected results. Based on response speed, clarity of impact sound, and ease of Velocity Control, compact solenoid with a shorter stroke win the selection.

Adjustments to Velocity are being made to reflect the solenoid's drive time.
Surprisingly, the resolution in milliseconds proved insufficient, necessitating subdivision down to microseconds (1/1000th).

Testing with the usual cat-themed sample audio.
Incidentally, while the audio source crashed within hours, the MCU side appears to be looping soundly even after over 13 hours of continuous operation.

The function to register the point at which to initiate a Ritardando had already been implemented, but I added switch and remote control settings that directly capture the Volume Level to enable this to be done more easily and intuitively.

The poorly performing HPF was also awkward to use, so I replaced it with an LPF by altering the constants to achieve better performance.
A pleasant surprise was that the characteristics of this newly added LPF worked well with the S&H waveform LFO.

The IMU implementation remains incomplete, but I've managed to port the code almost entirely.Though this device presents a higher initial adoption barrier than the Seeed Round Display, its gesture recognition capabilities are superb, and its performance is superior.

Added scales designed with modal playing techniques in mind.
The instrument's sound source plus pitch-followed MIDI note output is connected to a PC via USB, driving the Farilight CMI emulator Qasarbeach.
Mapping the sampled sound sources might yield interesting results.
