Hi, for setting global parameter changes from the E1 into a Oberheim Matrix 6/6R/1000, a checksum is needed. I find no info on how the checksum is made.
What I know is that the Master Parameter Data Message is constructed as follows:
F0H 10H 06 03H <version> <data> <checksum> F7H
whereby
-
<version>
= 03H for Matrix-1000 , and I believe it to remain blank for Matrix 6 -
<data>
= parameter number (00-57), followed by value byte -
<checksum>
= checksum of packed<data>
Does anyone know how to make the checksum?
Source of the parameter number I found here (not verified), in appendix E:
