Here is my first panel, to edit the effects from a Roland GP-8 guitar effects processor.
It cannot load any parameter values from the GP-8, it can only set parameter values.

I all,
I would like to find a way to get the correct value for the checksum 3e in this example
F0 50 2C 04 00 11 00 10 20 00 00 01 xx xx 00 SUM F7
the checksum is the summation between ( ) so the sum of 14 bytes before the SUM starting at 50.
xx xx are 8 bit data
F0 ( 50 2C 04 00 11 00 10 20 00 00 01 00 00 00 ) 3e F7
50 + 2C + 04 + 00 + 11 + 00 + 10 + 20 + 00 + 00 + 01 + 00 + 00 + 00 =. 3E
If I use external 8-bit checksum calculator it works perfectly but I can’t find a way in CTRLR, any idea ?
In CTRLR The Zy calculation seems not to be the right solution because I need to include the 12 bytes before the calculation and if I use y with greater value than 9 the result is always 0.
Regards

This panel isn’t finished, but all controls are working.
To do:
. add sysex dumps to & from the unit
. add bank for storing user patches
