Hello Fellow Musicians and Audio Nutjobs,
I'm new here to the forum, but not new to audio production, post-production, and live audio. I am fairly new, however, to computer audio devices and their technologies. I have done a lot of research and know a little about ADAT structure and clocking and the sort. To start off with my personal audio gear collection, I purchased an M-Audio Profire 2626, 8 XLR splitters and an 8-channel 25' XLR snake. I already have a 3-year-old MacBook Pro 15" Unibody maxed on RAM running Snow Leopard. This allows me to leech off XLR feeds just before they reach a live audio mixer for the house mains, monitors, etc. and not deal with the many gain stages inside the mixer. I have plans to double this setup to be able to record 16 channels (and on and on, yadda yadda) and connect through the ADAT ports. Part of the setup includes routing (on the MBP) an on-the-fly "mix" using headphones and the Profire control panel to Audacity on a Powerbook G4 for quick conversion to CD to give to the performing band. Also, I use an external hard drive (with FW400 and USB ports) via FW400 to record to since it is the only hard drive I have that operates faster than 5400 RPM (it's rated at 7200 RPM). I try to use a high sample rate of 96k/24bit even for live recording.
To quit beating around the bush, I have been doing a few live recordings with this setup and ran into a funky problem. The Profire Control Panel freezes up, yet audio still reaches all the right places (Pro Tools, outputs, etc.) From experience, if I try to restart the control panel, the Profire 2626 connection is severed and the recording is interrupted. I did a search and came up with a thread and tried some of those tips (iMac--->FW400 HD----->profire 2626 issues
). Since I only use the onboard mic preamps (for now), I disabled the ADAT and S/PDIF ports to limit FW bandwidth. I also switched the hard drive over to USB for a session last week and it had issues after a while with the computer "seeing" it and I wound up recording to the internal hard drive for the rest without incident. On Saturday, I did a gig and made sure those ports on the Profire 2626 were disabled, and plugged the Profire directly to the computer and plugged the hard drive via FW400 into the Profire 2626. After a few minutes of recording, the Profire Control Panel froze, but as before, I was able to record.
Is there anything I am doing wrong, or anything I should try? I have a recording session where the Profire is going to be used and I will be relying on the Control Panel to do its job. Thanks in advance.
