The Scarlet Devil Mansion :: CL-MeltySynth
CL-MeltySynth is a SoundFont MIDI synthesizer library written entirely in Common Lisp. This is a port of the excellent MeltySynth by Sinshu, expanded with new features. There is also my equivalent library for Crystal, Haematite.
Versions of "midi123" prior to v2.0 were written in Common Lisp and used CL-MeltySynth.
