This story reminded me to clean up a very different synth and put it on github:

https://github.com/wildsparx/synthem80

Unlike NSynth, synthem80 is directed to a specific and humble goal - make early 80s-style arcade sounds. It uses a mini-language to control an engine similar to that in Pacman.

For instance, the sound when Pacman eats a ghost:

    ./synthem80 -o eat-monster.sw 'timer(t=0.5) wav(wf=1 f=2 a=45) add(a=< b=48) nmc(wf=5 f=<)'
