Alright... I have tried recording with this rig before and had a couple episodes where the bass drum echoed and sounded like hell, but with the new studio completed I just did our first recording running 13 tracks simultaneously there were severe echoes and everything was out of sync...
Here is our signal chain: we are recording in two rooms with the walls down. The drums come through muffled but they come through - eventually we'll glass off everything but that is not for now. We are pretty much recording a practice space right now.
We go into an Alesis 32 to two ADATS - we use the optical outs of the ADATS to a Sonorus card.
The recording program we use right now is Sony Vegas.. I just upgraded to the newest one hoping this would eliminate the echoes we had in the past but the problem is persistent. I would like to know if this is a known issue in Vegas and if I should try another program. Any help would be appreciated. Thanks.

May 09, 2007 06:35 am Do things echo when they're solo'd? If not then maybe it's bleed coming from other mics. If the echo is there when solo'd are you playing back through speakers with the mics still on? Maybe the mics are picking up what's coming out of the speakers. Otherwise i'm really not sure what's causing this, very odd.
As for everything being out of sync, is everything using a similar signal path - as in does it all go through the Alesis 32 to ADAT to sonorus or are some signals making shorter journeys to vegas (ha!)? If they are then that may be causing the problem.
Some questions are so hard to answer without actually being there to take a look.

That was my first thought as well.
May 09, 2007 12:49 pm Everything does run through the same signal chain. We also do have monitors in the room right now, so that may well be the problem. I was just weirded out because we had used this setup before in a different space and didn't have the problem much. We only actually had the problem in the past when we recorded something that was over 15 minutes or so in length. I figured it was a flaw in Vegas and that the update might fix it, and I was highly alarmed when it happened through the whole damn recording.
I just need to try the whole setup again. I'll give more info when we practice again later on this week...

May 10, 2007 10:53 pm You may also have a problem in the way you are routing the signal. Possibly sending a monitered signal back into the board which is in turn being sent back to the recorder. Here is a link to the manual for the Alesis 32 that might help straighten things out. www.alesis.com/downloads/...io32_Manual.pdf
But indeed you could be picking up signal from other sources as well. The fact that things seem out of sync leads to possible latency in the audio card, the ADATS and the card not being locked timing wise. Can you describe the whole signal chain from input's all the way through to the monitoring section.
