Vortex Sound Research

Hey all, I'm very new to raspberry pi as well as modular language... I'd like to make something with a raspberry pi that would be a very simple, stripped down cv generator. something that could make an 8-16 step sequence or just a single tone would be great.

I was thinking like a USB port out or something? I don't have a big set up and I'm pretty strapped for cash with a friend whose letting go of a lot of pi stuff and I thought I'd enquire to see if anyone has tried this or succeeded?

​

thanks a lot
