Note: The Anchor field value affects only sequenced playback of the sample. Live
keyboard playing triggers the sample at the anchor point, so any sample data that
precedes this is not played.
• Loop parameters: You can control all aspects of zone loops with these options.
• Loop ON/OFF button: Turn on to enable looping and to set other loop parameters.
• Loop Mode pop-up menu: Choose a looping mode.
• Forward: Playback cycles from the loop start point to the loop end point while you
hold a key.
• Reverse: Playback cycles from the loop end point to the loop start point while you
hold a key.
• Alternate: Playback continuously cycles from the loop start point to the loop end
point, then switches from the loop end point to the loop start point, while you
hold a key.
• Play to End on Release ON/OFF button: Turn on to continue playback to the end
marker position after you have released the key—provided that the amp release
time is long enough for the audio portion after the loop to be audible. This feature is
useful for allowing the natural decay of a sampled acoustic instrument to be heard
during the envelope release phase, for example.
• (Loop) Start and End fields: Use to define the loop start and end points, allowing you
to loop a portion of the audio file.
• Tune field: Change the tuning of the looped portion of the audio file in cent
increments.
• Xfade (Crossfade) field: Use to define the crossfade time between the loop end and
loop start points. In a crossfaded loop, there is no step between the loop end and
loop start points. The higher the value, the longer the crossfade and the smoother
the transition between the loop end and start points. This is especially convenient
with samples that are hard to loop, and would normally produce clicks at the
transition point—the join in the loop.
• E. Pwr (Equal Power) ON/OFF button: Turn on to enable an exponential crossfade
curve that causes a volume boost of 3dB in the middle of the crossfade range. This
fades the join between the loop end and start points at an equal volume level.
Note: The ideal settings for the Xfade and E. Pwr parameters depend on the sample
material. A loop that cycles reasonably smoothly is the best starting point for a
perfectly crossfaded loop, but a crossfaded loop does not always sound better.
Experiment with both parameters to learn how, when, and where they work best.
• Audio File Tail parameters: Use these options to add and control a sample that is
added to the end of a zone. This is typically used to add a reverb tail, or a section of
reversed audio, but you are free to use any audio material.
• Name pop-up menu: Displays the audio file tail filename. Missing files are
indicated with an icon in a column to the left. Click to open a shortcut menu that
contains file handling commands.
• Tune field: Tune the audio file tail.
• Volume field: Set the overall output level of the audio file tail.
• (Audio File Tail) Start and End fields: Set the audio file tail start and end points,
respectively.
