My Q-LINK question (no precise)

I'm spanish, sorry 4ma english.

in my MPC 1000 (v 2.1) My first Q-link (in a upside) is not precise when i edit a sample. I'm push the AFTER button and move the q-link, and the line not responds to movement precise....

Can anyone tell me something about this? is a problem?

Thanks 4all

its precise .. if u want realtime check to see thats its not on noteon.. play with it some ul see..

when i edit a sample, i'm push a after button and a qlink. when stop in a position, the cursor move to start or end or a random position... it's normal?
