I recently found out there is problem with midi playback inside my Cubase. Basically every time Cubase plays midi tracks differently. It seems this cause by midi jitter and it plays notes early or late by milliseconds. This is noticeable when I play mixture of audio and midi tracks.
I ran a null-test to make sure it’s a problem with midi playback and not the audio, so I created a “Groove Agent One” instrumental track and programmed a simple beat at 120 BPM. Then I exported the track as an audio and imported it back in and flipped the phase of the audio track. So in reality there shouldn’t be any sounds when I play them together. But I easily can hear drum parts are out of phase.
I’ve tested same thing in pro tools and everything seems to be fine. If jitter causes by my system why there is no problem in Pro tools?
This is a big issue for me when I have midis and audio tracks in a project. Or when I bounce Vst instruments as an audio and bring them back into the project.
This problem only occurs during the playback and not the final Audio mixdown. Also I’ve tested the same thing with Mbox2 and Presonus Firebox, so I guess this doesn’t cause by Audio Devices.
I’m running Cubase 5.5.2 and windows Xp sp3.
Any comments and help would be appreciated.
