Eventually, we plan to add a UGen to Minim that will allow you to control the generating speed of any other UGen, but that got me thinking about how you might do something similar with existing components. So, I struck upon the idea of using an Oscil as a looping sampler by using an audio file as the Waveform and setting the frequency of the Oscil to be very low. The fun thing about this is that if you set the Oscil to a negative frequency, the sound will play in reverse. Additionally, I thought it’d be fun to be able to automate the changing of the frequency by having an LFO control the frequency of each Oscil (left and right channels of the original audio file). So here’s a sketch that lets you play with this setup:
