Hello,
This is probably something that's really easily solved, but....
I'm having trouble using multiple Amplitube amp sim on Logic Pro,
Created a new track, applied amplitube as a plug in, recored some bass using one of the bass sims.
Then created a second track, applied amplitube again, recorded some distorted guitar, but this also altered the amplitube settings on the bass track.
So it must be something to do with how Logic records the tracks, as a clean channel I think. Is there a way to change this and actually record parts with the amplitube amps sims on and not as a clean channel?
