I have added Soulsby Synths to the “Links” section.
You REALLY need to see this – a range of synthesisers based on Arduino hardware and using 8-bit technology.
The ATMegaTron stands out – it’s really four synths in one – you can change the software and overlays.. I want the special edition OdyTron..
There’s also a cut-down, kit version called the MiniATMegaTRon..
I am considering BOTH.. however my funds are locked into Amazon, and there is NO Soulsby gear on there..
