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 ....)

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.
