Ok I'm not a total noob in this area but up to now I've been recording only one track at a time. I use an M-Audio Fast Track USB interface and various preamps, depending on what I'm recording. But multi-track recording is something totally new to me. I know it takes more computer power and a multi-track interface. But I have a few questions. Here goes...
Ok, let's say I were to get this:
http://www.behringer.com/EN/Products/ADA8000.aspx
"The ADA8000 is a state-of-the-art 8-channel A/D (Analog to Digital) and D/A converter with 8 built-in IMP (Invisible Microphone Preamps) microphone preamps.
The Technical Stuff
Signal conversion in the ADA8000 can take place at either 44.1 or 48 kHz with 24-bit resolution. The ADATŪ inputs and outputs can be operated independently, as long as there is an identical wordclock signal. Frequency range is an ultra-wide 10 Hz to 21 kHz at a 48 kHz sampling rate.
The Ins and Outs
Connections are provided for balanced XLR and 1/4" TRS, as well as unbalanced 1/4" TS inputs. Line Out connectors provide either balanced or unbalanced connectivity. Digital I/O is handled via a TOSLINK optical socket, which supports up to eight (8) channels of data."
There are two connections on the back that say "SYNC", one IN and one OUT. I understand that these are used to sync the interface with what's playing on the PC, so that when recording a new track (super awesome solo) is aligned properly with the rest of the audio (rhythm section). Where do these connect? What am I looking for? A soundcard that has these on board? Can someone point me to a product so that I can at least read about it? It's one of those situations where I don't know the answer, and don't really know what to ask either.
Also, would Sonar work with this interface? It only has TOSLink to the computer. Is that a problem?
----------------
On another note, this is kind of irritating, but I have an M-Audio Fast Track USB interface that I use to record bass (line-in) and guitar (miked). No matter what I've tried, it only records to the right channel. For everything I record, I have to pan some to the left (in the software, after it has been recorded) to balance it out. I've tried a mono-to-stereo adapter but that didn't help. Its the same problem. It does this in Goldwave and Audacity. Is there a way around this?
Sorry for the novel.
