Hi. I'm hoping this isn't odd and that it happens to everyone all the time but I get the feeling it doesn't! Using Reaper I am playing the sounds in a Nord Drum 3 via midi rather than hitting the pads with a stick. That's all dandy until I unplug my laptop from A/C to run on the battery (to avoid ground loop noise) and then the Nord loses time, stops, gains time and is generally out of any kind of sync until I plug the laptop back in when it's fine again. Anyone have any idea what the hell is going on here?

I think I have solved why this is happening but don't know if it should be happening. I raisd the buffer size in my uc fireface to 512 from 256 and the problems (which also included crackling) go. To test further I lowered the buffer size to 96 and with the laptop on battery power the whole thing is all over the place but when plugged in to a/c all is well. Is this a common thing to have to increase the buffer size of an interface when running a laptop on batteries?

I suspect what you are seeing is down to different power management when on battery power. Try setting the power management scheme to maximum performance for battery power and see if that makes a difference.
