MMA developer beta 10.12a available

[bvdp]

I've uploaded a new "developer" tarball to

    http://mellowood.ca/mma/downloads.html#developer

for you testing and enjoyment. Some neat features here:

     Grace notes in solo/melody strings
     MIDIWHEEL to control pitchbend
     Improved MIDIVOLUME stuff
     ChannelInit command to configure midi stuff at startup
   
and the regular bunch of bug fixes.
