Hello, a little late to this discussion, not trying to hijack it or anything but just wanted to ask: do the modifications to outdated code referenced in this thread also apply to the super basic version of the ultrasonic theremin found here?:
https://projects.raspberrypi.org/en/projects/ultrasonic-theremin
I’m not ready for the dual theremin, pimoroni version yet, I’d be happy to get the breadboard/one sensor/buncha jumpers/intended for grade school age kids five years ago version to work on my Pi 4 if possible
