Drumulator : with RISC-V processors.

And meanwhile, I'm making progress on the subject.

And it doesn't have to be simple! My goal is to make it 'easy' and not too expensive to manufacture. The idea is to design a quality machine that has a good sound.

The options to consider, the best use of available resources, and other considerations mean that it takes a little time to develop. But in the end, I enjoy that moment when, after many development difficulties, I feel that the final solution is taking shape.

Rather than designing a test circuit and then going through the cycle of testing and modifying the circuit, this time I preferred to use already available development boards. Obviously, this makes the development look a bit DIY, but in the end, it goes pretty well.

To facilitate the development of the machine, I opted for a modular design. That is to say that for the moment, I am focusing on the analog part in order to start by producing the audio output board which will be easily connected to the operating core of the machine which will have to copy the operation of the original Drumulator.

So now I'm at the stage of creating the schematic. I'll have to make the board and then run the tests. This is a process that, despite the ease of having electronic equipment made today, still requires a bit of time. But there you go, the subject seems to be off to a good start...
