I'm recording with a Powerbook G4, on to an external hard drive with Logic Audio 6. I use an Edirol PCR-A30 usb midi-controller which has built in A/D converters. I record at 24bit, 48kHz. When I record, the audio take is always about 50 - 100 ms behind the beat (no, it's not just my bad timing). I checked it by recording the click track and it's pretty consistent. I always have to slide the starting point of the audio object over after each take.
Does anyone know of any settings to correct this?
