Akai MPC TOUCH User Manual page 170

Use the Root Note field to set the root note of the sample. This defines which note will play the sample
at its original pitch when in a keygroup program.
Use the Slice field to display either the sample as it has been edited (Pad) or the entire sample (All).
The Link Slices button does not work in Program Mode.
0 Snap forces start points, end points, and loop points to occur only at the waveform's "zero-
crossings." This can help to avoid clicks and glitches when playing a sample.
To enable or disable 0 Snap, press and hold Shift, and then tap 0 Snap at the bottom edge of the
touchscreen.
To enable or disable the loop function, press and hold Shift, and then tap Loop at the bottom of the
touchscreen. This switches the loop function between Forward and off. The loop function is described
earlier.
