midi channel warning is gone

[Keith OHara]

The message
 warning: MIDI channel wrapped around
 warning: remapping modulo 16
has gone away in 2.12.53

In the old version, each staff got a midi channel, and if we had more than 14 
staves we got this message.  My response was to make a separate score for midi, 
grouping instruments on fewer staves.

Now each Voice="name" with a unique name gets a midi channel.  Does the 
attached midi or the .ly below sound like an orchestra to you?
If not, I'll start working on a tiny version.
