Arturia Minilab 3 SysEx messages

I was mainly interested in finding out how to change pad colours.

There was this Github repo detailing some SysEx messages for Minilab 2, but that didn't work for Minilab 3.

In the end I downloaded the DAW integration scripts from the Resources page and decompiled the Bitwig Java classes (you need to unzip the .bwextension file). That gave me the coveted secret SysEx commands :)

Raspberry Pi Pico PIO 8 Pin UART TX

This code creates a UART TX on 8 sequential pins of the Raspberry Pi Pico. The main use case being MIDI splitter devices

The second 16 port implementation should work for any number of pins, but just acts as a pure copy to those pins instead of having individual control over every pin of every byte. Hence while less flexible, the controlling software is simpler (just send a uart byte and it's copied to every pin).

Only tested in the simulator so far. https://wokwi.com/projects/344345628967436882

Used https://wokwi.com/tools/pioasm to go from uart_tx.pio.h to uart_tx.h
