The Sample Edit page also houses Speed and Tune controls:
Speed – There are a total of 4 Speed controls at your disposal: 1/4 (quarter speed), 1/2 (half speed), x1 (normal speed) and x2 (double speed). Selecting a speed will multiply the speed of the Sample playback by the amount selected.
Tune – You can use the slider in the Tune section to pitch a Sample up or down by semitone.
When hovering in the Tune section you can also adjust the tuning of the Loop by clicking on the +/-12 buttons to adjust the tuning by one octave, and +/-1 to adjust the tuning by one semitone.
Clicking on the Auto button will automatically set the tune of your Sample to match the session key. For example, if the Kit is in the key of A Maj and you have a Sample in C Maj, selecting Auto will tune the Loop down a minor 3rd to match the Kit’s key.
