• Rate knob: Set the duration of each arpeggiator step. When Sync is on the arpeggiator
is synchronized with the project tempo, and Rate is set in bars/beats. When Sync is
off, the Rate knob sets a constant length for each step which is unaffected by project
tempo changes.
• Octave knob: Determine if the arpeggiator pattern is played only at its original pitch or
across higher octaves when the pattern is repeated.
• Length knob: Set the length of each arpeggiated note. At the maximum setting of 100%
the length of each note is a full step. Set the length to lower values to generate shorter
notes for a more staccato effect (if triggering a sound with a fast release time).
• Pattern knob: Choose the active pattern in the step sequencer section to the right.
Sixteen different step sequencer patterns can be created and edited for each
arpeggiator. By default, all patterns are identical, so this parameter has no effect until
your patterns are edited.
• Swing knob: Change the timing of the arpeggiator, moving even-numbered steps to
later positions without changing the timing of odd-numbered steps. This can add a
more relaxed feel or groove to the part. Swing generally works best when combined with
a Rate knob setting of 1/4 of a beat (16th note swing feel) or a Rate knob setting of 1/2 a
beat (8th note swing).
• Note Vel knob: Determine how the arpeggiator handles note velocity values. Arp
sequencer 1 modulates arpeggiator Amp values by default. When Note Vel is set to a
value of 0%, the step values of Arp sequencer 1 determine the velocities of notes in the
arpeggiator pattern. When Note Vel is set to a value of 100%, arpeggiator pattern note
velocities are determined by incoming MIDI velocities. Intermediate Note Vel values
blend the Arp sequencer step values with incoming MIDI velocities.
• Split knob: Set the highest MIDI note number to be included in the arpeggiator
pattern. Notes above this value are not arpeggiated. Set to the maximum value (G8) to
arpeggiate all MIDI input.
• Latch knob: Hold the arpeggiator pattern when you lift your hands from the keyboard in
Hold or Add mode. Set to Off to stop the arpeggiator pattern when you lift your hands.
• Hold: Newly played notes are organized into a new pattern, which replaces the
existing pattern.
• Add: Newly played notes are added to the existing pattern.
Tip: Try combining As Played mode with the Add latch setting to create an
interactive step sequencer with up to 128 steps.
