Ivan told a story about the early days of Laserium where they used a couple of old army surplus signal generators to do Danube's lissijous figures. There was a rumor before a show that Patty Hurst had been seen in the park. So when a capacitor in one of the signal generators went "bang" everyone hit the floor thinking it was a shoot out between the FBI and the SLA.
I'm sure somebody makes a digital to analog converter for your Raspberry Pi. You can always write one. With an analog to digital converter & a pot you'd ever be able to play it.
