VSTi sync problem

Hi, I have 2 tracks. An audio track(drum loop) and a track with a VSTi(Vanguard). If I insert an effect plugin that delays the sound(f.inst. ReaFir) on the master channel, the VSTi track no longer plays in sync. I can insert ReaFir without any problems on the individual tracks. Is this a bug or am I doing something wrong? Bo

Just noticed it only happens when the VSTi track is armed for recording. So it's no big deal. Bo

its this and IMO it
