All I know is a friend of mine used Pro Tools LE to record his band. They did track the drums to Pro Tools HD, because, well, that's what a friend's real studio here in Philly uses. Anyway, Digi 002, API 512 and Sytek MPX-4Aii mic preamps, an old MCI console's preamps for the drums... the record sounds freaking awesome. Then they licensed a song from it for season #2 or #3 of the OC, and another song from the record is in a major motion picture film movie. So it is possible to do professional recordings with Pro Tools LE. I personally use a Black Lion modded 828mk2 and it sounds amazing. I can't wait to start recording my friends' next record from the ground up with my setup, and some borrowed API preamps. It'll sound killer.
So, define professional? Kelley Stoltz is making waves and touring the country and his songs are in commercials in Europe and he records everything in the living room of his SF apartment to a Tascam 388:
And it fits his music well and sounds great.
My main beef with Pro Tools is the dongle thing. If I was going to get into an LE rig, I would want one that would enable to have a setup like I do now with my BLA 828mk2 and DP for home on the G5, that same system portable with my PowerBook, but also a system that will run off of the computer's internal sound card, like DP, because I like to edit, compose, etc at my girlfriend's house, etc.
I guess I have a loyalty to DP, since I have been a MOTU user since 1995 when I discovered Performer at college. Aside from the dongle thing, I have no problem with PT, but I have a lot of money invested in a DP rig and unless MOTU goes out of business or drops the ball something fierce, I'll continue to use DP. If I have a job that will pays well (I freelance with audio) and requires me to use Pro Tools
and will pay for a Digi 003 rig (which I will clock to my BLA 828mk2), then I'll learn Pro Tools and use that as well.
But until then I'm strictly using DP and Live.
