# Arpeggiator

Arpeggiator window

The Arpeggiator turns a chord into an arpeggio.

The arpeggio pattern is fully customizable:
Key 1..Key 4 are the keys that are currently being played, with Key 1 being the lowest in pitch. Random Key selects a random note from the currently held keys. You can choose one (or no) key for each step.
Octave Up / Octave Down can be checked to transpose the note.
Accent can be checked to make the note a bit louder. See the Accent knob.

The following controls are available:

- Steps: The number of steps in the pattern. The maximum value is 32.
- Rate: The speed at which the steps are played. It can be "standard" notes like 1/16 or triplets.
- Accent: Sets how much velocity is added to notes with the Accent box checked.
- Swing: The amount by which 2nd, 4th, 6th (and so on) steps are delayed. 50% means "no swing".
- Gate: The (relative) note duration. Turn this down to make the notes sound more staccato.
- Fixed Velocity: Ignores the velocity of incoming notes and uses a fixed value (90) instead.
- Hold: Ignores incoming note-off messages so the arpeggio keeps playing after you release the keys. The notes will stop when you play a new chord. This feature can make using the Arpeggiator with a MIDI keyboard easier. You can press and release the sustain pedal to stop the Arpeggiator.
