Disklavier

Hi Hans

I have also studied the files of the Pianosoft disks. A friend of 
mine wrote a program to play the Disk Orchestra Collection and 
Pianosoft disks from a computer. This program was used like a jukebox 
and sent midi data out to an expander.

The data I have for F3 and F4 is as follows:

F3 xx     Short time delay (00-7F) (1/1536 Bar) (600Hex=1 Bar)
F4 ll hh  Long time delay  (hh*80+ll) (ll,hh 00-7F)

Offset 33 hex from beging off file is the Tempo byte mostly 58 

Now can you help me?

I would like to know what the following bytes do:

In the Header off set from the start
Offset 17 hex         80 00 40 00 50 00
Offset 23 hex         01 58   or 01 E5  or 01 02  all at offset 23H

I do not have access to a Disklavier (only a CVP) so I am unable to 
change bytes to see what they do.

Hope this has been of some help to you.

Regards

Midi Magic
