2.3.3. Transport section
Press the Play/Pause button, hold down some keys and the arpeggiator will start. You can
add up to 32 notes to an arpeggio. Please read Chapter 5 [p.52] to learn how to do this.
Press the Play/Pause button again to pause the arpeggio pattern, and a second time to
resume playback from where you stopped. You can also restart the arpeggio while it's still
running by holding Shift and pressing Play/Pause.
To start a new arpeggio pattern press the Stop button, press Play and hold down some keys.

It will be more obvious what the different Arp Modes do when you are holding down three or more
keys.
2.3.4. Set the tempo
Use the Rate knob or the Tap button to adjust the playback tempo. You can also set the exact
tempo of the arpeggio pattern before starting the arpeggiator by pressing the Tap button a
few times.
With the MIDI Control Center you can specify how many taps of the Tap button it takes to
adjust the tempo, and also how the Rate knob will respond when it is turned. See Chapter 9
[p.74] for more information.
Remember: Tap tempo and the Rate knob will not function when KeyStep 37 is set to one of
the external sync sources.

♪: Hold Shift+Rate to make decimal tempo adjustments
2.3.5. Time Division
The Time Division encoder allows you to change the rhythmic relationship of the arpeggio
relative to the tempo: quarter notes (one step per beat), eighth notes (two steps per beat),
and so on. Triplet values are offered as well (1/4T, 1/8T, etc.).
When you turn the Div knob while holding Shift, the time division does not take effect
immediately, but only after you release the Shift button. This allows for smooth transitions
between different time divisions.
