Neat idea. What about doing tempo along with pitch - faster tempo combined with higher pitch and slower tempo combined with lower pitch? Throw in a way to switch directions (forward, reverse) and it seems like that would be an even closer approximation of scratching. For example - you choose a midpoint of your control range. The first value to either side of the midpoint changes direction of playback (mid + 1 == forward and mid - 1 == reverse). Then as the control values get further away from the mid you increase/decrease pitch and tempo. The difficulty would be establishing that mid point (and limiting the change of direction to only two single control values) via a typical controller. Seems possible with a computer or maybe an outboard midi filter. How configurable is the DBeam?
