Definately get the tutorial on the lower right hand corner of this site.
Just like you, I worked on fl, from v4.52, all the way up to the current version (v9).
FL is a great program, but the sequencer is wack to me.
Now I mainly use FL for recording vocals, and effects/tracking.
Everything in that tut is hands on, so you're not boring yourself dizzy reading page after page.
They also give you all the sounds you need to do the lessons, and the way it's set up, if you follow instructions just right, you'll have a whole disk of working .pgm's and sounds to use on your own when you're finished.
Like you, I never touched an mpc before I got one, and by the time I got to page 69 of the tut, I made my first beat on the mpc, which was kind of banging.
I haven't looked back since.
I'm in the process of doing my 3rd album, and I can't wait to drop those fresh mpc tracks.
Don't get me wrong, FL is an awesome program.
It will take just about any plugin you stick in.
You can make some bangers on FL, and even make tracks people would think you did on an mpc, but it will NEVER sound just LIKE an mpc track, or any beat machine track for that matter.
I used to record FL tracks to 1/4" tape, or 4 track cassette.
I always got the sound close, but not the swing.
IMHO, that's the best 39.99 you'll ever spend, besides what you pay for the machine!
