SX I think.
I had both Cubase 5 and SX running on the same P.C, I could layer 2 kicks. One from the P.C and one from the Akai and they would sit together in time. That was on windows 98.
On SX it would move out of synth ever so many beats causing the kicks to phase and sometimes just loose it all together.
It wasnt a huge problem at the time as i was working mainly in the pc. It is now tho, puts me off a lil.
I was just wondering if anyone else had this problem.
Mind you, i havnt tried what pat said so...
