Im pretty sure u have to choose an input and closest I can get is Gearbox but Acid isnt heairng the metronome going. Ive been looking at drum machines and virtual drummers and I have loops I bought from Sony but with the loops, to build a drum section, itd be with single drum strike and load them 1 by 1 to get the exact sound I want so Im leaning towards the "virtual drums" software to go along with my Line 6 Gearbox. thanx for the help and Im open for any info on the virtual drummer thing, as well.
