Reply to VCI-100 Scratching

This might be a dumb question, but.. does anyone know how to configure Traktor Scratch Pro + VCI 100 SE to scratch like this WITH the pitch bend working (1:05)? I can only seem to scratch with a constant BPM and I have never been able to figure it out myself. I've looked everywhere from the guides to the Controller Manager. Do I need something else or another hardware? Any help would be appreciated!
