Trim speed on Mpc 1000 too FINE???

i have an mpc 1000 and im having trouble with trimming samples..

whenever i try to trim a sample by spinning the data wheel it takes ages to move across the sample. it takes hundreds of rotations to get to the part i want to get to..

the length of the sample is only 2 seconds long sometimes like a kick and snare.

I was wondering if you could help me speep up the sensitivity with my data wheel in trim mode.

its too fine

thanks
