# MES Arpeggiator

> MES Arpeggiator is a creative MIDI arpeggiator and pattern generator for electronic music producers using iPhone, iPad, AUv3 hosts, and DAWs.

## What it is

MES Arpeggiator is a music app and plugin by Make Electronic Sound.

It helps producers turn simple chords into evolving MIDI patterns, rhythmic arpeggios, harmonic phrases, and musical sequences.

It is available for iPhone and iPad as:

- a standalone app
- an AUv3 MIDI plugin

## Important clarification

When used as an AUv3 MIDI plugin, MES Arpeggiator generates MIDI. It controls other synths, samplers, or instruments. It does not output audio as a synth inside the AUv3 MIDI effect.

The standalone version includes a built-in FM synth for auditioning ideas.
