thanks formant, i was hoping to find a way to use the midi tracks instead of audio tracks because pro tools le only gives you about 32 audio tracks to work with, but i guess i should still be able to do load the beat and track the vocals with 32 tracks.
Another way you can do this is by wiring each of FL's channels to channels in PT and you can do this utlizing: Bus and Aux tracks (audio tracks as well)
Hit record and play and record the tracks one by one or all at the same time into PT. This is really only beneficial if you are tracking through amps and other gear to color your sounds or even plugins (in PT)
