[A6] Saving mix over sysex

[Geoff Moehrke]

No - I have never worked for Alesis.  I wrote a patch editor for the QS
series synths and the A6 uses many of the same conventions with respect
to the way Programs and Mixes are stored and transferred via sysex.  The
information I posted was based on my experience with sysex on the QS
synths, review of the A6 sysex specs and some limited experimental
programming work with the A6.
