I have this appaling problem using cubase sx. As soon as I start trying to record midi the timing goes very erratic. Every other bar a beat will be delayed by a noticeable amount making recording literally impossible.
During playback the timing seems fine.

I have heard people have problems with recording timing being slightly off and people having to shift their recordings along abit but my problem is not a slight delay but a random erratic behaviour.

I use a emagic Unitor 8 midi interface normally but have tried disabling it and just using the midi interface on my scope card. It causes there ill effects mostly on external synths/sound modules. When using VSTs I dont get so much of a delay but going into record mode does create crackles and the like.

Im using Windows XP on an intel i850 box. I tried upgrading to directx 9 but that made no difference. Im using SFP3.1c.
I have win xp installed in regular mode with ACPI. Could this be causing the problem?

Has anyone has this or know a way to cure it?

yes, ACPI is most likely your culprit. I spent a good deal of time banging my head over a new WinXP installation (old HD died) and realized I forgot to do Standard PC upon installation. After doing a post-install switch, everything's back to normal, though if you don't mind starting from scratch, you're better off doing a fresh install as Standard PC. Though you can get work done, and when it works it works well, it can cause a fairly irritating random set of glitches from a terrifying 'insert boot disk' message (which goes away when you reboot) to the occasional blue screen or reboot (like when you start up CubaseSX and then zap you're rebooting). It's tolerable, but if I weren't redoing my setup in a month or so anyway, I'd start all over again after thoroughly backing up.

Hope that helps,
Sam

Are you saying that installing Standard mode causes these glitches and bluescreens or Switching to standard mode afterwards causes them?
