[rec.music.synth] DX7 internals

cs@mat500.materna.de (Christian Strzyz) (04/05/91)

First thanks to John G., Christophe D., Darren A., Mitch S. & Paul D.D.

DX7 patches may be found:
(1) ucsd.edu         midi/patches/DX7
(2) louie.udel.edu   pub/midi/patches/DX7     (seem to contain the same as 1)

So my next question comes in line because I want to reduce these over 9000
presets: What format does these 4096 (32*128) bytes have, what's their 
correspondance to certain voice parameters. Or more global:

         Is there any documentation of the internals of the DX7 ??? 
                 (Does Yamaha provides such a service ?)

Any help appreciated.
