OK. Here I use 'midi_channels' as 'MIDI comformant data channels' for 
struct amdtp_stream.

I know nothing. As long as I know, in BeBoB and Fireworks models, 
maximum number of 'MIDI comformant data channel' is 1 and 'maximum 
number of MPX-MIDI data channel' is 2.

Should I limit the number of MIDI comformant data channel by 1?


Thank you
