Crackling sound from TI desktop

[DJTOMMYBOY]

I have been getting a weird sound when having my TI inserted in a track. Its very bizzare.....If I uninsert it from the track the crackling is gone. Im using the TI as a VST plugin

Im using Logic 7.2 on a powermac G5 with 2.5 gigs of memory and a motu 828MKII firewire interface.



Any suggestons?? :?
