are stored internally, a substituted patch may not 'fit', so some swapping
of patch locations would be necessary. This may not please all users.
This can be accomplished through the standard 'upgrade' procedure.

putting my favorite patches into .mid format and using the S1 card, I can
reprogram a certain number of 'static' factory patch locations within the -8
with the my own - in effect, I can 'roll my own' VG-8?
(giddiness rising - Ok, calm down, Calm DOWN!) Is that right? Hooooo!
Boy, I'm glad I stayed with my VG-8! So, I guess the big issue is to get
them into a .mid format? How does one do that? And, THEN get access to an
By chance does anyone know where the 'S1' patches start - I guess it would
start at a certain 'bank' number?
Makes sense now that I think about it - using the S1 card *would* be the
most convenient way to do this.
Any elaboration on this Nick would be appreciated.

or by going into maintenance mode on the '8 and dumping the OS to
a program that will accept the data.
It takes a fair amount of programming horsepower to get this to
o The file needs to be in .SYX format (to eliminate overhead)
o The .SYX data needs to be converted from 7-bit to 8-bit format
(uses the bit-shifting method)
o An additional byte needs to be added to the new patch to specify
the algorithm used.
o The replacement patch must be selectively compressed (in Roland
format) to fit, and it still may not fit (depending on the patch
algorithm used) - in which case, it must be swapped with one that
o Convert the modified file back to 7-bit format
o Recalculate the checksums
o Save the file (in .SYX format - again, low overhead)
o Send it to the '8 as an upgrade (yes, you need an S1 card).
Remember, you do this AT YOUR OWN RISK! Any errors in the file can
lock your '8 up tighter than a drum (no pun intended).
For anybody that would like to tackle this, I have a white paper describing
the technical details of the above. If there is enough interest, perhaps
Aure would be willing to post it on the site(?)
Anybody out there have an '88 service manual that describes how to get it
into maintenance mode?
