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.

It’s probably close to 50 years old…
I think there was a US remake of it, maybe?
Using a Raspberry Pi Pico as a Logic Analyzer with PulseView
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 Hackster How To article shows how to capture data to a CSV file for Sigrok Pulseview to examine. They have a MIDI protocol decoder among many others. (The Pico appears fast enough for I2C signals)
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)

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!

Nice project!
The pico seems to be way more capable than I thought.
Wow - Raspberry Pi Pico 2 announced today - and supports Arm and RISC-V cores!
Raspberry Pi Pico 2 is our new $5 microcontroller board, built on RP2350: our new high- performance, secure microcontroller. With a higher core clock speed, double the on-chip SRAM, double the on-board flash memory, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities, Raspberry Pi Pico 2 delivers a significant performance and feature boost, while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico series.

At a guessthe dual architecture plan is designed to get something out of the door so there will be a community, and support when the pico 3 comes out in arm flavor for $6 and risc flavor for $3.
It’s interesting that the register articles mentions courting the embedded industry with TrustZone support. Suggesting an arm only variant might make a tub of money, and the risc-v variant will be perfect for the more open boutique house.

What an upgrade!
RISC-V is a great bonus feature, so we can get some experience this stuff without a dedicated board.
I’m a bit sad that it still uses micro USB…
But I understand that it is important to keep it compatible with the original footprint for an easy replacement and to keep costs down.
Also there are enough other Pico based boards with USB C for some extra bucks.
Onboard OTP with 8kB and the secure system surely are nice things for companies,
ADC spikes have been fixed, nice!
