The RP2040 uses the Arduino_Pico environment which provides easy support for running code on the second core.

The standard Arduino functions setup() and loop() run on the first core. The second core runs setup1() and loop1().

As a test, I moved the LED blink 1hz to the second core and used the data communications provided by rp2040.fifi.push_nb(), rp2040.fifi.pop_nb(), and rp2040.fifi.available() to signal the second core when the first core was finished with its initialization.

More details are available here: https://arduino-pico.readthedocs.io/en/latest/multicore.html

(this enhancement would be applicable to all of the projects built for the RP2040)

I have tweaked your code a bit to run on my TTGO T9 and I'm using a Novation Launchkey MINI as keyboard and controller.
When I look into your midi mapping " z_conf.ino " I cant find any possible mapping to Control Change (CC) or Program Change (PC) messages. Could you provide an example on how to do that ?

when debugging MIDI on the ESP I can se that the messages are handled
ControlChange(rx): CH: 8 | number: 21, value: 61

Thanks for an awesome synth ( it is going to be my first euro rack module )

I am guessing it's difficult if not impossible to test all the hardware variations. I am seeing an error when using the RP2040 (eg Raspberry Pi PICO).

For all instances of Serial.printf() The compiler is reporting error: 'class arduino::UART' has no member named 'printf'.

This does not appear to be an issue with ESP32 boards.

Disregard. It's a compiler configuration mistake.
