I must congratulation you on the orange colour.
I can’t but help here this … . .

Bit before my time… I don’t really understand
UFO! Saturday morning TV was banned in our house when I was a kid so I missed it first time around. I watched the complete series during my pre-Covid bus commute. Very cheesy, but the theme tune is wicked! https://www.youtube.com/watch?v=j2PoXfZdYVU
I don’t believe that series made it to the new world. It does bring to mind the movie Galaxy Quest.

The open source Sigrok logic analyzer software runs on a number of platforms, it works with a variety of ‘smart instruments’ including an $8 Chinese Logic analyzer dongles running an old FPLA, connected to your PC.
The single C file is intended for the Pi foundation tool chain but may be a adaptable to the Arduino IDE plugin (or PlatformIO? let me know)
A couple RP2040 based programmable USB Keypads from from PIMORONI
Pico RGB Keypad Base with 4x4 smart LED rainbow-illuminated keypad
Solder in your Raspberry Pi Pico £21.90
Keybow 2040 4x4 USB Keypad £49.50
A more compact design with an integrated chip.
the first one is already out of stock ! while I found the second one a bit expensive … but anyway these are interesting products.
This looks good… I’m glad someone has done this. Any for sale? Any test units?
The PIO might be useful for some quick format conversion of signals, but I don’t know if the cores can accomplish much 24 bit signal processing, certainly the availability of the rp2040 is a plus.
A Cortex M4, like in the ATSAMD51 could do a lot more, (apparently the Cortex-M4F is the variation with hardware floating point) Adafruit, who have regular posts regarding chip shortages, seem to be out of stock of a lot of their ATSAMD51 boards.
The powerful Cortex-M7 used in the Teensy 4.0 , 4.1 could do some tricky effects, he is expecting a shipment of the NXP chips finally in January (some Teensy 3.x chips are delayed until June 2023.)
His *Audio System Design Tool" allows one to visually design a process chain and output Arduino source code. It works with his Cortex M4 boards as well.
I ran across the HackaDay write up on a Euro Rack implementation of that board?, mentioning Vult DSP transcompiler…
just followed through to the PicoADK-FreeRTOS-Template link, where I noticed the helpful fixed point function library: src/vultin.cpp along with the vultsrc/dsp.vult it gets a surprising amount of work done by the rp2040.
Hey, Datanoise here, the maker of the PicoADK. A small amount of boards is left and 80 more to be ordered as soon as possible!
The code examples actually work well even with polyphonic Vult DSP based synths with a simple echo. More is possible as well. A ladder filter and state variable filter also works well!
Here’s an intruiguing project
Nice project!
The pico seems to be way more capable than I thought.
