Chapter 2 Playing Patterns (Pattern Play Mode)
■ Changing the Bass Pitch
(Fret Shift)
You can shift the entire tuning of the bass sound.
1. Hold down [SHIFT] and press [BASS]
(FRET SHIFT).
2. Hold down [SHIFT] and rotate the TEMPO/
VALUE dial to select the number of frets
you want to shift by.
fig.02-06
Setting a negative value (-) shifts the pitch
down; setting a positive value (+) shifts the
pitch up.
One fret is equivalent to a half-step change
in pitch; any value from -5 to +16 can be set.
To play the pitches of the fifth string of
a five-string bass (low B), set Fret Shift
to -5. You can then use Key Pads E, 13–
16 to perform the fifth string’s low notes
(from open string to the fourth fret).

[SHIFT].
You’re returned to the Pattern Play Mode
screen.
* The Fret Shift function is not enabled during
pattern playback.
Playing with Special
Performance Techniques
You can play rolls and flams when using the
key pads to play drum sounds.
Roll: This is a technique where the same
sound is continuously repeated with the
same timing or interval between the sounds.
Flam: In this performance technique, a stick
is held in each hand, and each stick strikes
the snare (or other instrument) with a very
slight difference in timing and force.
* You cannot use roll and flam performances with
bass sounds.
■ Playing Rolls
1. While holding down [ROLL], press a key
pad.
