A Question, for anyone that knows how MI firmware code works
I'd definitely recommend setting up the build environment via vagrant.

Using a Raspberry Pi Pico as a cheap multi-channel DAC for pitch CV
Hi all, I'm making a Eurorack sequencer module with 4 pitch CV outputs (NOT audio) and I've noticed that DACs are kind of a pain due to being expensive, SMT-only & still requiring buffering with op amps. I figure that a good alternative would be to buy a Raspberry Pi Pico for $4 which will give me 8 PWM outputs that I would then hook up to an output stage like the one in the europi (shown here: https://github.com/Allen-Synthesis/EuroPi/blob/main/hardware/EuroPi/schematic/europi_schematic.pdf)

What is your favorite open source eurorack module? And the best documented?
Bom has links for sourcing parts

Is it really necessary to put opamps in front of my ADC inputs?
Up until now I've been using the analog input stage from the EuroPi schematic as my model for a CV in. You can see it here:

Easiest/cheapest way to get multiple (9-12) analog cv outputs (0-5V volt) from a single microcontroller/arduino
There is no super cheap way to get a lot of analog outputs from an MCU. Filtered PWM is your best bet for cost effectiveness (I recommend looking at the EuroPi from allen synthesis : https://github.com/Allen-Synthesis/EuroPi). Otherwise if PWM doesn't work for you, you'll need to look into DAC chips. The MCP4728 is a good spot to start, it's 12-bit and has 4 channels: https://www.adafruit.com/product/4470. Since it's I2C controlled you can have multiple of them on one bus. Maybe looking into a 16 channel PWM driver for a lot of outputs: https://www.adafruit.com/product/815. Hope this helps!

My Raspberry Pi Pico based Eurorack module has a new software release!
The project is completely open-source and open hardware, and the contributors together have made this big list of scripts that you can run using a menu system!

My reprogrammable DIY module (EuroPi) has just had a new free software release!
The project is entirely open-source but I do also sell the Panel+PCBs on my site!

Firmware hacking with Uncertainty
EuroPi Turing Machine script is feeding the Uncertainty cv input with pulse 1 opening an envelope on Maths for voice 1 & 2, pulse 2 opens the second Maths envelope for sub osc voice 3. A little delay added for texture. That's pretty much it!

A Question, for anyone that knows how MI firmware code works
The patch.init() is still a great way to start, but you could save some money ditching the audio i/o and build yourself an EuroPi. However, that requires DIY, obviously.
