Project get Distorted when adding SI Drums

[Donal McCarron]

Hi There

I am currently  working on a a project but find when I add SI Drums( a pre-defined beat from the library in ROCK section) it seems to distortion the whole thing on playback??

I have added Guitar initially with Effects from FH3 and then Bass using Amps/Cabs also from FH3 and all seems to be fine but when I add the drums its seems to distort the whole thing.

Has anyone else come across this issue? Also is there a preferred precedence when recording tracks to stop this happening I.e. Drums first,  then Bass then Guitar etc. ?

Any help in this would be appreciated
