Firewire/USB combination problems
« on: May 16, 2005, 01:11:53 PM »

Hi,

I have a Apogee MiniMe (USB) and a MOTU 896 (Firewire)that I use together when I track drums. After I started using this setup (Apogee for room-mics and MOTU for close miking)I have noticed that there is a delay on the Apogee-tracks compared to the others. First I thought it was just because of the time delay between mics, but today I checked it more closely. I put up two microphones, each one at the same distance from a snaredrum (about 2 inches). I recorded one through the Apogee and one through the MOTU. I then checked in my editor window in DP4.5. Guess what? The Apogee track is about 1200 samples later than the MOTU (44.1 kHz) Shocked

Anyone have any idea on what is happening?

BTW, the Apogee is set up as a master clock for the MOTU.



Thanks

1200 samples at 44.1KHz? That is 27msec delay. Are you sure you measured it right?

DP4.5 marks all the beats i a soundfile, so what I did was to set the main counter to samples and check at what location the beats were. The difference were 1200 samples.
