Thanks for the info. I recently have switched to the Mac. My PC was getting dated and in need of an upgrade so I decided it was a good time to make the switch. What attracted me to Biab was the realtracks and realdrums. I'm mostly interested in country and old standard songs and using realtracks and realdrums for a backup band sounds pretty good. That's why I'm asking for suggestions on putting together a system to get the best sound for jamming. I might be able to get a lambda computer interface for next to nothing. Would it do the same thing as the Apogee interface you described?
I have never done anything with midi an am just picking up bits and pieces on how it is used by looking through the forums. But am I right in thinking I need some sort of midi keyboard to use Native Instrument Kontakt 4?
