How do you gradualy increase the volume on a single track?

I have owned an MPC2500 for around a week now so im not all that clued up yet.

I want to gradually increase the volume on a single track, is there an easy way to do this rather than alter the volume figures? Do i use realtime?

Cheers.

you can assign volume to the q-link and record the q-link automation in a track, done
