Pro Tools LE 8 Midi Pitch Bend Problem

[W Sound]

Here's the problem...

I'm working on some dubstep/dance recordings. When using any VI in Pro Tools, the Pitch Bend works fine when I'm not recording, but as soon as I start to record in pitch bend info, it seems to get 'stuck' on certain notes along the way (basically, it doesn't monitor the triggered sounds correctly while recording).

It is, however, recording the midi info into the session correctly, because if I play it back after recording, the 'sticking' of notes doesn't happen any more.

This is not a controller problem, as I have tested it out on several midi controllers, and everything is fine while recording except the pitch bend!

please help

...I'm guessing that silence means I am going to have to upgrade to PT 10
