OK so I'm about to embark on creating some beats in Pro Tools 8. I have an M-Audio Oxygen Midi controller, and would like to use this to take say a guitar sample, slice up each note, or perhaps a group of notes in the sample, and allow it to be played via a specific key hit... how do I make this happen? So I need third party plugins/software? Will REX files work better? (Not sure about REX, just know I have them, and that may be the answer??) perhaps Kontakt? (Not sure about this either?) any help appreciated. Thanks in advance.
