In Arp mode you can customize the way the notes of the played chord will be arpeggiated by
adjusting following settings:
Element Description
LOCK (Button 2) Keeps the Arp feature enabled even when you leave Arp mode. For
example, this can be useful to adjust the chord settings, switch to
another Pattern, adjust Plug-in parameters, etc., while keeping
arpeggios running. If Arp is locked, when you switch to another

you that Arp is on.

SHIFT + NOTE REPEAT at any time to
enable/disable LOCK .

the pads can be released and the arpeggiated notes will continue to
play. Press
HOLD (Button 3) again to stop the arpeggiator.
