Using mtr to create "automation"...

Hello,

I've set up the mtr object to control the panning and volume changes of a track, to create sort of an automation effect, the data of the panning and volume changes record in fine, but when playing back the mtr responds much slower and panning and volume changes are slower and further back in the track, meaning they are completely out of time. Is there any way of getting mtr to replay the data at the same speed as it was recorded?

Thanks in advance! :)
