Latency or other problem?

[Sonic Flash]

Technically, I'm not a 100% noob, but I could imagine this question to be considered so.

I recorded some midi tracks in Cubase AI4, piano, bass and drums.

The piano and drums play back as usual, but the bass, for the first time, has a delay of almost a bar, which I cannot solve by any of the asio settings. When I play the instrument realtime, it's all good. But when I play it back from the recording, the monster 'latency' kicks in. The notes really are synchronised in the key editor!

Only thing I can think of: instead of the Yamaha KX49 keyboard, I've now been using a very old electric piano thru a midi-usb interface. But I fail to see how this could affect playback.

Specs:
- Vista laptop: 3GB of memory, Pentium Dual Core
- Cubase AI4
- Asio4all driver

I've never had this before, and I've been using this (less than ideal, i know) setup for a while now (except for the electric piano as a controller).

Any suggestions would be appreciated!

if you are using vst plugins as instruments then some of the plugins have larger latency than the others. try to change the instrument and see if problem stays. i have the same problem with trilogy in fl studio.

Thanks Seidy.

I started a new project, using the same instruments, and all was OK. Maybe it was a glitch in the software? Or I accidentally hit a switch or something...
