@@ -40,13 +40,13 @@ There seems to be two possible ways to figure that out.
1st - when 4th bit is also active, and first value byte is 03
then add 80 to value
So for above example:
ID = 3009 (hex) = 12297 (decimal)
Position = 0
One of possible values is 0. Usually value range is 0 to 99,
albeit in some cases it's different - you have to check what values can
X-Edit assign (there doesn't seem to be any sanity check in firmware)
This is especially needed for IDs that set some effect type.
