I would appreciate any help with the following questions:

1)Will the QY-100 record full SYSEX for Roland keyboards?
2)Can these Sysex messages be edited and/or
inserted on the QY?
3)Is the QY-100 practical to use in a live
situation to play back SMFs? I read that
it can only hold 20 songs in memory; so
how much time and button-pushing to load
more songs from the SmartMedia card?
4)I read something in the manual and am not
clear on this: Can you send it a
"SONG SELECT #" while in Pattern Play mode and be able to change and access it's internal patterns on the fly (next pattern
starts at the top of the measure)?
Thanks.
