oh and there's a Circuit Python port of course: circuitpython.org/board/weenoi...

("Noise Nugget" is the audio focused dev board with the rp2040 that is powering PGB-1)

even the rp2040 is excellent for synths. That's what we use for our PGB-1 groove box weenoisemakers.com/pgb-1/

And it's open-source! A great fit for the AdaFruit shop, if I may say so myself ^^

I spent a little bit of time making an alternative firmware turning the PGB-1 into a live chord player instrument. Here's a demo track youtube.com/shorts/AUz3I... and a more detailed presentation youtu.be/Lo8R7m40x2k

I'm at Embedded World with AdaCore, demoing a cute little robot programmed in Ada and SPARK 🤖 (booth 4A-128) #embeddedworld #ew25

Not to dismiss the technical side of things, but I've always considered Rust's biggest achievement to be its marketing :)

This can work for pre-conditions, but for post-conditions you have to check at all return/exit points of your subprogram, and it will get messy very quickly. In Ada/SPARK the contracts are part of the subprogram specification, so they are visible to the users of the API.

It's nice to see SPARK listed in the memory safe language, but it's not in the formal methods 😕

SPARK is both memory safe and an industrial grade formally verifiable language.

Sad for the open-source synth scene, excited to see what's next 😊

I don't know how to take it ^^

I just implemented phase distortion synthesis for my pocket groove box, it's a great technic to play with .

We have completed the production prototype of the PGB-1 🥳🎹🎶 Thanks to pcbway.com and their great vacuum casting service we were able to prototype a rubber keypad that greatly improves the quality of our tiny groovebox. More info here: www.crowdsupply.com/wee-noise-ma...

I use FreeCad. It takes some time to get started, and sometimes the model will break when I change parameters 🤷‍♂️ Still a useful piece of software. I strongly recommend watching tutorials on parametric design (internal spreadsheet in the software for part dimensions) early on.
