I came across an interesting synthesizer recently from the 4k demo scene.
Called sonant it allows complex scores to be synthesized from very compact code. YouthUprising’s sonanttool.exe is still used to convert .snt files to .h files for use with the synth.
Trouble is it doesn’t compile under Windows/Linux … until now!
The ported code uses Michael McTiernan’s Wavlib (http://www.mcternan.me.uk/MCS/Downloads/WavLib.zip) for cross-platform .wav file generation
