Robert, I believe the firmware in my Mark II XG is version 1.44, as that 
was the
latest download that I received from Yamaha which I still on my 
computer. (I'm
not certain on how to show the firmware revision number on my piano.) 
I'm just
trying to find some commonality between our systems.

R: Danny, I have a Mark II only, not an XG, so we'll surely have 
different ROM versions (and, perhaps, different characteristics).  Mine 
has two different ROMs:

1) PK CTL ROM: Version 2.03 (Apr 4, 1995) (Power on with the L&R buttons 
pressed; press "+" once; press "Song Select Fwd".)

2) Sensor Prgm ROM: Version 1.24 (Dec 14, 1993) (Power on with the L&R 
pressed; press "+" twice; press "Song Select Fwd".)

{My ROMs are just that (not EPROMs) and had to be physically changed out.)

BTW, in the comparisons you two are making and describing, are you 
playing the MIDI files from a diskette in the DKV drive or from an 
external computer?
