I guess using BIAB will safe a lot of time to make demos....
I use it all the time for building the basic tracks for the rhythm section and the structure of the arrangement.. use the real tracks versions and the players sound really good... I use the drums for click track references to set the groove of most everything I record... at least until the percussionist gets his parts in.. and do the same for each of the others, keys and bass.. of course you can spend hours just finding the style for the tune.. but hey it's part of the fun... i guess. oh yeah and I build the charts from it to distribute to the players as well.. makes it easy to do projects with my keyboardist in Los Angeles and bassist in Burlington NC and me in Atlanta...
couldn't do that in the 80's... man
