Will do, theres not really any special "codes" of such, to trigger off the fret slides and board taps they are just at different octaves of the voice's sample range...

what you will need to do is use 2 tracks for 1 mega voice...

in one track u have all the notes which u need to transpose as you change chords. On the second track u use the notes in the upper octaves that you don’t want transposed because these are the element noises of the guitar body. In the Yamaha u can have all this on one track and it is smart so it doesn’t transpose the element noises in the higher octaves. Unless… with the Roland u can assign certain octaves to NOT transpose with chord changes…
