A better alternative to the Raspberry Pi which is more suited for musical applications (and currently much cheaper) is the Daisy Seed by Electro-Smith[0]. You can program it in C++ / Pure Data / Arduino and Max/MSP Gen~. The community is very helpful and there are plenty of examples to start with. They also provide a few options to get started with some knobs/buttons. I'm not affiliated with them, just admire the whole ecosystem.
