Re: [fluid-dev] loading and unloading a SoundFont

This is a problem I also had when I started using FluidSynth. The  
command line tool doesn't accept file paths with spaces. I recommend  
using library calls instead, they have no problems with spaces in paths.

The ID of a SoundFont is pretty irrelevant. The command line tool  
automatically sets all available channels to the new soundfont when  
you load it. You only need the ID to identify a soundfont after you  
loaded it, so you won't need it at all as long if you only load one  
SoundFont at the same time. I don't know about the ID limit, though.

Afaik GAMBAS is somewhat similar to REALbasic. You might want to look  
at the code of the REALbasic FluidSynth Wrapper I'm developing on  
SourceForge if you need help with accessing the FluidSynth library. I  
didn't make a release yet, but you can get the code via subversion:
