Calculate Checksum

2013-07-21 by djheikotnt

Hey all,

i need help :-)

I want to control an old Roland gs synth (eg-101) with sysex from bcr2000


this device has for example effect (Reverb mode)

Room 1: F0 41 10 00 18 12 40 01 30 00 0F F7 (0F= Checksum)
Room 2: F0 41 10 00 18 12 40 01 30 01 0E F7 (0E= Checksum)
Room 3: F0 41 10 00 18 12 40 01 30 02 0D F7 (0D= Checksum)
Hall 1: F0 41 10 00 18 12 40 01 30 03 0C F7 (0C= Checksum)
Hall 2: ; F0 41 10 00 18 12 40 01 30 04 0B F7 (0B= Checksum)
Plate: F0 41 10 00 18 12 40 01 30 05 0A F7 (0A= Checksum)
Delay: F0 41 10 00 18 12 40 01 30 06 09 F7 (09= Checksum)
Panning Delay:F0 41 10 00 18 12 40 01 30 07 08 F7 (08= Checksum)


I tried to config this and know that's wrong.

# Hall Mode 0-7

$encoder 1
.showvalue on
.mode 1dot
.resolution 24 24 24 24
.default 0
.minmax 0 7
.tx $F0 $41 $10 $00 $18 $12 $40 $01 $30 val $0F $F7

But it doesn't work. i know that the checksum "0F" need to be calculated from 40 01 30 00

any idea's?
