CircuitPython MIDI synth w/ new synthio.Note API makes fat sounds!

CircuitPython can now do per-oscillator frequency, waveform, amplitude envelope, and more. This means we can stack detuned oscillators to get a really fat sound. Here's some examples.
The entire program running on the ‪@adafruit‬ QTPy RP2040 is less than 100 lines long.

Can’t believe all of that is coming out of a QT Py. We live in exciting times. Sounds amazing, this is mind blowing stuff.

sick! owo

Speaking as someone who has a load of CircuitPython-compatible boards waiting in a drawer for a project, someone with a load of I2S DACs knocking around, and someone for whom modular synthesis has been settling into the brain of, I can hand-on-heart say that I can't wait for the stable 8.1 release 😀

Dude what the what!

Amazing work!! how have you connected your Arturia to QTPY ?

[@todbot]

Thanks! I’m using a DAW on my laptop (Ableton Live) as a MIDI router, but it would work just as well with serial MIDI, but that requires extra wiring

[@VarunPant3]

@@todbot Thanks, serial Midi as in something like CP2102 ?

[@todbot]

@@VarunPant3 not quite. MIDI was originally just a serial (UART) protocol using a 5-pin DIN connector to let synths talk to each other. This was before USB. Every microcontroller can speak this kind of MIDI without an extra chip. The CP2102 is a USB-to-UART chip. So you could use it to make a USB-to-serial MIDI interface. But for communicating between a MIDI controller and a MIDI synth, no USB is required.

So amazing. What is the QT Py pink USB cable going into?

[@todbot]

Thanks! Both the QTPy and the MIDI keyboard are going into a laptop running a DAW acting as a USB MIDI router. I could’ve wired up a standard MIDI input on the QTPy, but that was more wiring :)

WTF !!! Ca me trou le cul comme dirait Cartman.

[@DaveNelsondotcom]

One of the devices on your breadboard is a QTPy RP2040, but what is the other device? I would guess an amp.

[@todbot]

It's a cheapie stereo I2S DAC, a PCM5102. You can get them off Amazon or similar for a few bucks.
