you can take a mid point
.default $2000
it will now wrap a limited number of times in either direction

so you should now be in business (?)

if you need less than 0 to 127 use smaller val ie val0.3 for 16 values or val0 for 2 values

Yes, the value inside the BCR is always altered. That is there is only one value for each controller not one for each direction.

turn p 15,16, 0, 1, 2 - now turn n 1, 0, 16 for val0.3

I'm not sure

Yes but I'm keeping them to myself
