Subject: [bc2000] Script? help needed...

  
 
 
 
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.
