## What is Arp Arpeggiator?

Hold a chord. Arp sets it in motion.

Arp is a one-octave arpeggiator and pocket instrument. Press and hold notes on a single octave of keys, and Arp animates them into tempo-synced patterns — a moving line of light across the keys you're holding. When you find something you love, export it as MIDI in one tap and drop it straight into your DAW.

No menus, no manual. One screen, built to be played.

FIVE VOICES
Warm, Pad, Bass, Pluck, and Bell — five hand-tuned synth voices, from soft ambient swells to bright plucked lines.

PATTERNS THAT PLAY YOUR CHORD
Up, down, up-down, random, and as-played. Hold or latch a chord and shape it live.

FEEL CONTROLS
Tempo-synced rates from whole notes to 1/32, gate length from staccato to legato, BPM with tap tempo.

ONE-TAP MIDI EXPORT
Capture the playing arpeggio as a standard MIDI file and share it to your DAW, sampler, or collaborator. Your idea leaves the app as easily as it arrived.

DESIGNED TO BE CALM
A near-black canvas, a single glowing accent, and light that responds to your touch. No ads, no account, no tracking — nothing between you and the instrument.

Arp is the second instrument from Fecit Audio, makers of Tap.
