yo desert ease, i've been trying to fool around a little but i'm still getting situated on this move thing. I can't for the life of me find a good sample to flip. I can however tell you how I usually go about doing my thing in FL Studio.
I'll find a sample and chop it up into a 4 beat loop and then i'll bring it into FL Studio.
If I don't know the tempo of the song that I've sampled from, i'll just adjust the tempo in FL Studio up or down until the sample actually loops
if i want to transpose and play the loop in a different key and still keep the loop on tempo, I don't mess with the piano key in step edit or in piano roll because this speeds up or slows the sample down. I go to the time stretch tab and adjust the pitch knob by 100% increments. each 100 increments is a note(octave) higher or lower. I usually can't go above positive 600% without hearing any artifacts unless the sample is very high quality.
the beat I heard definitely sounded like you new what you were doing and. Is it a technique specifically that you want to do or do better in FL Studio?
