than one drum event occurs on the same sub-beat, the PAGE UP/DOWN buttons step forward
or backward respectively through each drum one at a time.
If no drum event exists on this beat/sub-beat, the display will show no pad number, and
EMPTY in place of volume data.
To navigate through the steps at the current quantization rate, use the PAGE UP button to
move forward or PAGE DOWN to move backward. If a drum exists between those beats that
fall on the current quantization value, the drum will sound as you go past it, but the display
will not stop on that drum.
If swing is on, step mode will step in "swinged" increments (see section 2.2).
Background Step mode provides detailed Pattern editing. (Note that "step" does not refer to Song steps, but
to the steps in a Pattern that hold drum events.) You can move through a Pattern one step at a time, stop at each
event as desired, and delete the event, add an event, or change an event's volume. While occasionally somewhat
tedious, Step Edit mode allows editing drum parts to your exact specifications.
Each step (also called a sub-beat) is 1/96th of a beat in duration, so at maximum resolution it takes 96 steps to
"move through" a quarter note. To save time, you can step through the Pattern at various note values, as set by
the quantization value (which is why it's preferable to select the quantization rate at which the Pattern was
recorded). Example: A 16th note consists of 24 sub-beats, so setting the quantization value to 1/16 lets you step
through the Pattern 24 sub-beats at a time. The following chart relates the number of sub-beats to
note/quantization values.
