Tav, There are a load of sound cards on the market with break out boxes allowing 4 or 8 or 10 or whatever line signals to be recorded simultaneously. Usually the card will come with software which has been prewritten to cater for the sound card, so it knows to create a seperate wav file for each line input. As we're usually dealing with line inputs it would be desirable to have the mics first hit a mixer which has direct outs on each channel, and have the direct outs going to the break out box, although the card I have (Maxi Studio Isis, discontinued I think but always one ebay) seems to cope fine with the mics direct. The thing is, even if you have to use specialist software that recognises your sound cards 8 inputs or whatever (ie. my Maxi Studio Isis has a special version of Logic Audio thats written to cope with the card) you have the flexibility of using the wav files in any audio multitrack software. I prefer to mix all my stuff in Nuendo or Cubase, although my PC always runs into latency problems when I try to record with these programs, so I record using a much lower spec program Sony Vegas. Its a good idea to set a tempo map, and keeping the same tempo map across the various applications you use. Even if you're not going to play along to a click, if you want to punch in a solo on one track right at the end, its going to be pointless recording from the very start of the song, especially if you're low on disk space.... so find a snap point and punch in there, then in the other program find the same snap point and drag the wav file there......dragging wave files all over the place isn't always great and will lead to lost sync, so better organised you start, the better chance you stand of migrating your project to different apps.....this probably doesn't help or answer any questions! hehe, heres some cool gear though... http://www.dolphinmusic.co.uk/d2/page/shop/browse/category_id/098175452abe956a3718429239ca9a5d
