I'm curious about how this config file is going to be used. The interest
I have in a MIDI instrument querying API is the querying protocol
itself. I thought that the synth on the other end of the MIDI port (say
an ALSA sequencer port) would just interface to this API. No need to
know how this synth stores the actual patch info. It could be in a sound
font or a fixed set of sounds for an analog synth. How useful would a
static config file be in this API? Perhaps I'm missing something.. Ohh,
a thought just occurred to me. You're probably thinking of this for
external MIDI devices that don't have a method of communicating what
patches they have? Hmm. Sorry for my ramblings :) Cheers!
