A few notes:

- It might be easier to implement the old MIDI Kit on top of midi2.

- That way you could also use midi2 user space drivers from the old MIDI

- midi2 is the preferred MIDI Kit for R5.

- There are user space drivers available for USB MIDI interfaces for the
midi2 kit.
I have an Emagic AMT8
 http://www.emagic.de/english/products/hardware/amt8.html )
for which I wrote a simple user space midi2 driver. Writing the old MIDI Kit
so that
BMidiPort accesses a driver directly would make adding support for
devices harder, requiring a kernel driver. Having the old MIDI Kit access
either through midi2 or a plugin architecture would allow user space

- From the MIDI application on BeBits, I think at least 8Slots, Chochoito
, Keyboard keyboard, KMidiLevelMeter, KMidiMixer, KMidiPlay, MidiPaint
, MidiSynth, Patch Studio, Rack747, Sequitur, serial_midi_server,
, Mev, PecoBeat and (my own) MIDI Mixer, MIDI clock generator and MIDI
Keyboard (which I recently open sourced,
ftp://sipkema-digital.com/midikeyboard153GPL.tar.gz ) all use the midi2 Kit
and DrumView, HoneyFx
, Qua, Dynamic Composer I am not sure of, maybe even some others. That is
