I was planning to replace the SoundFont loader in my code (inherited from FluidSynth as you know) with the corresponding code from libInstPatch (the code would be C++-ified, of course ;)).
At the moment I'm planning to begin from
IpatchSF2Reader.c and IpatchRiffParser.c. Any advice on additional files I may need to look into or anything else that could help me with the porting?
