I have sone considerable work determining file formats for WK-7500/WK-7600, primarily with tone (.TN7)
files and DSP (.DS7) files, using a reverse engineering approach, as follows:
1) Job 1 is to get all tone files stored on my computer's hard drive. This requires the tedious
mind-numbing process of loading each of the 800-odd tones into the User tone area and transferring them
from there to my hard drive using Data Manager. Like:
a) Load the 35 tones in group A (piano) into User tones 1-35
Save these 35 User Tones to my hard drive in directory A
Some groups (like H) have more than 100 tones, so I load the first 100, save them,
and then load the remainder.
I will attempt to attach a compressed (rar_TN7.rar) file containing all WK-7600 tone files.
The format of the tone files can then be discerned by observing the minimum, maximum, and variation
of each byte in these files, and by using the tone editor to make changes and observe how each change
affects the binary contents of the tone file.
Finally, I attach the source code of a visual basic program I use to manipulate tone and dsp files,
which contains the complete format of tone files and dsp files. It turns out that the latter portion of
each tone file is in the exact format of a dsp file.
The program contains a variety of utility routines, such as using a single tone file with pleasing effects,
and applying those plesing effects to each of the 100 User tones in a second or 2. I maintain several
sets of 100 user tones (stored as PK7 files and can load any such desired set from my computter to the WK-7600-
within about 20 seconds. I will also attach a number of these PK7 files, each containing 100 user tones.
