I haven't been able to set the BCR up for negative number eg -7 to 7
with a 7bit signed number, MostSignificantBit is set to mean that the number is negative but you should simply think of the 7 bits going round a circle joined at 0 (126 127 0 1 2 etc)
-2 $7E
-1 $7F
0 $00
1 $01
2 $02
What negative numbers do you need to use?

You would think that this can be done as the whole 127 range is used.
That is -63 to 63 is the same as 0 to 127 starting at 63.
This could be true and it is worth trying out
$encoder 1
.showvalue on
.minmax 0 127
.default 63
.tx $F0 $10 $06 $06 20 val $F7 whatever your sysex message needs to be
but if the values are true negative (called ones complement, as shown above) then we are in trouble as the encoder when it reaches 0 will just keep putting out a value of 0 no matter how much you turn it anticlockwise. If you find out a way to make it go around in a circle let me know.

No idea, sorry. I don't have the sysex docs for the Matrix 1000. try the above and see what happens.

Check your MIDI connections/cables and the power into the BCR as this shouldn't happen
