I have had this idea kicking around idea for a percussion synthesizer device, probably based on an STM32F103. Today I found a document on the ST web site explaining how to generate 12-bit stereo using the built-in DACs. Super simple – all you need is a pair of RC filters and an audio jack!
There is something a little perverse about embedding what ends up being a softsynth into a piece of hardware, but I really like having a dedicated UI for my audio gear, and I like not having to deal with all the complexity and uncertainty of a computer.
