Thanks for the doc - seems to be basically the same as the tx81z manual.

The "usability" problems with the tx81z driver that I am solving are all
to do with allowing the user to dump/request one patch/performance at a
time without having to get request an entire bank:

1) not possible to request individual patches without front panel
interaction (i.e. switching to patch to trigger the VCED dump)
2) not possible to request a specific bank I/A/B/C/D without front panel
interaction (i.e. Voice Trans function in util menu)
3) current driver doesn't support performances at all.

I haven't done anything about 1) yet, but I don't believe there is a way
to request individual patches without remote control functionality. I
intend to solve this by updating the programme change table so that it
includes the patch I am after, doing a programme change to that patch,
then remote controling the play/perform button to make it transmit the
VCED data. Also I'm not convinced that the single patch store
functionality in the TX81z driver is correct so if it turns out to be
wrong after I do some testing on it I intend to make this operate similarly.
2) When you send the 32-patch VMEM dump message (F0,43,2n,04,F7) I
presume it sends in return bank I. But there are a total of 160 patches
including the factory banks A-D, and some users might want to dump banks
A-D themselves. So I have implemented remote control functionality which
accesses the bank Voice Trans function from the utility menu to dump any
of the banks. This is in SVN at the moment.
3) PMEM request dumps (and presumably stores) all performances, but
there is no remote method to request or store an individual performance
apart from using remote control functionality. so tonight I have been
working on the remote control functionality to do this.

If there are any methods to carry out these operations without resorting
to the remote control commands it would be great if you let me know!
