Thanks David for your advice on my worry about extending the midi-channel limit. I am a fair way into the OSX coding, and I should learn a lot more about fluid synth in the process.
I also note your suggestion that jOrgan is worth a look. I totally agree. They have a pretty active group in Queensland Australia, and have obviously tread the paths I am just starting on. The main obstacles are the installation and setup, and also at first reading it appears to be restrictive in terms of its input, expecting midi streams, and distinguishing those by the port that they arrived on. The serial port format that I am delivering to OSX knows nothing of midi, and provides just the switch settings and a bus indicator.
