I don't committed any important patch, applied only some maintenance
modifies, anyway on local sources and as a personal experiment i'm
including PatchBay in InternalMIDI.

No. i played with MIDISynth connecting it to InternalMIDI also via
PatchBay, and work as well in Haiku but have latency problems, the
sound seems ok.
(remember that Haiku doesn't have sf2 installed by default if you want to try)

I think that MIDIPlayer should remain simple as concept, maybe there
are some nice features to be added.
My idea for a sort of midi preferences is related for example to
select different sf2 files.

Haiku have support for both old and new midi_kit, far as i know.

i'm curious to find where are the latency problems, maybe in media_kit?
