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
