Use the Pad Loop button to cycle through the available
Pad Loop modes.
Important: For Pad Loop to work, you must (1) set the
Sample Play field to Note On instead of One Shot and (2)
set the Slice field to Pad instead of All or a slice number.
Off: The sample will not loop.
Forward: You can hold down the pad to cause
that sample to repeat from the Loop Position
to the end of the sample. Release the pad to
stop the repeating playback.
Reverse: You can hold down the pad to cause
that sample to play in reverse, repeating from
the end of the sample to the Loop Position.
Release the pad to stop the repeating playback.
Alternating: You can hold down the pad to
cause that sample to play from the Loop
Position to the end of the sample and then play
in reverse until it reaches the Loop Position
again. This will repeat as long as you are
holding the pad down. Release the pad to stop
the repeating playback.
Use the Loop Position slider to determine the position (in
samples) where the pad's playback will repeat when Pad
Loop is activated.
Note: When Loop Lock is on, the loop position is the
same as the pad start (as determined in the third Samples
tab). When off, the loop position is independent from the
pad start.
Pan Velocity
Use the Pan knob to adjust the stereo placement of the
respective layer.
Use the Vel Start and Vel End knobs to define the velocity
range of each layer.
A range from 0 to 127 lets the layer respond to the entire
velocity range which is input from the respective pad while,
for example, a range from 100 to 127 lets the layer
respond only to higher velocity levels. By assigning several
samples of one instrument, you can create a realistic-
sounding "multi-sample" by adjusting the velocity ranges
of each layer accordingly.
For example, you may have three samples of a piano key
with low force, medium force, and high force. You can set
each sample to a layer and set the Velocity ranges so only
low velocities trigger the low-force sample, only mid-range
velocities trigger the medium-force sample, and only high
velocities trigger the high-force sample.
Use the Root Note menu to set the starting note of each
loaded sample. Smp denotes the sample's default pitch.
