Get the original tune with the beats. Sync it with your beats (look at the wave forms, the drum beats should be obvious) and then use the same tempo change on the acapella. Or just beat match it by ear on cd decks...
I'm being well noobish but i really cant get fruity to do that shit &-) I Can chop it in bars but it still is hard to line up perfect.. plus there are shit loads of bars to arrange and it has to render everytime so it takes long
get acid or sumin like that.....set a 4x4 beat at what eva u want.export that into acid then mix the accapella in in acid.then after take the 4x4 beat out and then export ur new accapella into a wav....viola!
Click 'SMP' tab in the channel settings on the right.
'Time Stretching' under 'loop' points light.
Use 'MUL' knob, to left makes it faster, to the right, slower.
Use the 'PITCH' knob to adjust octave of sample.
TIPS: Use sections of samples, cut into bars id suggest.
Hold Ctrl key when turning the knobs, its give you more precise control when adjusting by 1% (Bigups SDM for that tip!).
Turn the 'SNAP' feature from 'LINE' to 'NONE' if the sample doesnt start on beat, just open the piano roll, an manually move the sample to where you want it to start.
Well thanks for all your help cause i've acually been able to sample a couple of bars out of an old reggae tune and mix it in fruity to match the beats I used the MUL knob rather than time stretching and with a bit of careful manouvering i got it perfect Thank you all!!
