Latency, Help clear the confusion Options

[DEVIOUS]

Hi everyone!

I know this topic has been allegedly done a thousand times, yet I have been scanning the pages and am still unclear on an important issue. As far I understand it, latency occurs when you are recording a new track and listening post processing through the computer. Many people have commented on how this can pose a problem, especially to USB audio interfaces. I have been told about direct monitoring- ie listening to the new track before it is processed but this has left me with some confusion.

If I buy a USB interface and record a track, then record another and use direct monitoring, I should be able to play in time yes? Does latency become more of a problem when you start laying down 20 or 30 audio tracks? I don't intend to record more than 2 simultaneously but do want to layer complex songs. Basically, I am intending to tip toe into the shallow end of computer production with a Tascam Us122 and Tracktion. However, I am starting to consider (if this will inhibit me recording more than a couple of tracks without the computer screwing around) investing in a s/h motu 428 and start with Tracktion, maybe moving to logic. I also will want to have a go with some soft synths and I know these are a potential problem for recording.

Please help us out!
