Bc2000 (for the BCF2000 & BCR2000)

I need to set an encoder to transmit a 10 bit pitch bend.

Its to emulate the 'alphatrack' controller. Its supported in REaper so i thought i would try to create a preset for it (BCR2000).

The alpha tracks documentation says...

Fader Move         e0 yy zz

Where yy is  3 LSB's in the from 00,10 .... 70
Where zz is  7 MSB's in the form 00,10, ... 7f
Together, yy and xx form a 10 bit fader position.



I have tried writing this into the script - but im failing :(
I think i need to use the .tx command.
i've tried - it should be easy as i have found an example for pitch bend at 14 bit - but it needs to be ten bit.
I can't even upload the 14 bit example.

Any help would be much appreciated.
