Gary:
I don't know anything about the differences between the DX7 and DX7s, but this
DX7 info may be useful. I posted this to r.m.s. before xmas.
I've seen many requests for public domain / shareware DX editors, but I've
never seen a definitive reply. They're usually along the lines of "I was
roaching around on CompuServe last month, and I think I remember seeing one..."
Anyway, hope this helps ...
=========================================================================
For those interested in unpacking the uscd.edu DX7 patch data, here is
DX7 data format information.
compiled from - the DX7 MIDI Data Format Sheet
- article by Steve DeFuria (Keyboard Jan 87)
- looking at what my DX7 spits out
I have kept the kinda weird notation used in the DX7 Data Sheet to reduce
typing errors. Where it doesn't quite make sense to me I've added comments.
(And I will not be liable for errors etc ....)

SYSEX MESSAGE: Parameter Change

0gggggpp ** parameter group # (g=0; voice, g=2; function)
0ppppppp ** parameter # (these are listed in next section)
Note that voice parameter #'s can go over 128 so
the pp bits in the group byte are either 00 for
par# 0-127 or 01 for par# 128-155. In the latter case
you add 128 to the 0ppppppp byte to compute par#.

a single voice dump. The OPERATOR ON/OFF parameter is not stored with the
voice, and is only transmitted or received while editing a voice. So it
only shows up in parameter change SYS-EX's.
