[sdiy] MIDI 2.0

[Amos]

... I should also mention that there's some talk about setting aside some
sysex IDs for non-commercial use (educational or DIY), or creating a
low-cost non-commercial tier of MMA membership, to lower the barrier to
entry for MIDI-CI development.  Details are TBD and, as someone pointed
out, it is slightly complicated by the fact that membership dues are one of
the MMA's only revenue streams and they do need to stay in business.  Even
volunteer-run non-profits (and the MMA is one) have overhead to take care
of.
