Hello hackaday.io, it's been a long time since I posted an update on this page.

The project evolved quite a lot, it is now a complete groovebox with 6 real-time digital synthesis tracks and two sample tracks. This means you can create complete music pieces on the PGB-1. I also changed hardware a few times, settling on the RP2040 for processing unit. With its two cores it's quite a powerful machine when used at its fullest.

Last but not least, I started a crowdfunding campaign on Crowd Supply for the PGB-1: https://www.crowdsupply.com/wee-noise-makers/wee-noise-makers-pgb-1
