Every programmer/musician (or music-curious) owes themselves a look at Supercollider https://supercollider.github.io/.

  // two band limited square waves thru a resonant low pass filter
  { RLPF.ar(Pulse.ar([100,250],0.5,0.1), XLine.kr(8000,400,5), 0.05) }.play;

It's really an incredibly interesting multi-paradigm language with elements of Smalltalk and J. The above code sounds great btw and is right out of the docs for `Pulse`.
