I'm an old C64 demoscener (6510 assembly coder), so there's no wonder why I was immediately smitten by the sounds from a MIDIBox SID v2 (MB-6582).
I knew I just HAD to learn to how to build one for myself.
I finally picked up a hot-iron ~Dec 2019 and I haven't managed to put it down yet. ;-)
The wealth of knowledge and community support in these forums is really amazing, so I'm quite happy to be part of it all now.
In addition to MIDIBox projects, I've also started getting into Mutable Instruments (Shruthi & Ambika) as well as various MCU projects, with STM32, ESP32, etc.
