MES Arpeggiator

MIDI Arpeggiator (AUv3)

$14.99 · Designed for iPad. Not verified for macOS.

MES Arpeggiator is a creative MIDI arpeggiator for iPhone and iPad, available as both a standalone app and an AUv3 MIDI plugin. Use it in plugin hosts (for example AUM and other AUv3 hosts) to drive your favourite synths, or run it standalone to sketch ideas quickly. At its core, MES Arpeggiator is about fast inspiration with musical results: choose a chord, set the feel, and generate evolving patterns that instantly fit your track. Shape the output with range, speed, gate and swing, then refine the pattern with hands-on performance controls. Built for real iOS workflows AUv3 MIDI plugin: load inside AUv3 hosts and route MIDI to instruments for instant musical results Standalone app: great for writing, sketching and experimenting away from a full session Built-in FM synthesizer (standalone): audition arpeggios immediately with punchy, musical FM sounds—perfect for previewing patterns before routing MIDI to other instruments Powerful pattern generation & control Skippable steps: choose which steps are active or muted in real-time to reshape the groove on the fly Euclidean rhythms: generate perfectly distributed pulses across your sequence—from simple grooves to complex polyrhythms with a single control Deep pattern control: adjust octave range and direction, then shift/translate patterns horizontally or vertically for evolving movement Loop controls: focus on a subsection with loop start/end/length—great for fills, variations and evolving sequences Advanced note timing: choose durations from 1/1 to 1/64, including dotted and triplet subdivisions for tight rhythmic control Gate & swing: sculpt note length and groove in real time without interrupting playback Randomization & presets: generate new patterns instantly, then save and recall favourites for fast workflow Visual feedback: the step grid shows active steps and play position so you always know exactly what the arpeggiator is doing Chord Board for instant harmony Open the Chord Board to pick chords quickly, change the root note and scale, and trigger harmonies that feed straight into the arpeggiator—an easy way to go from “blank page” to musical progression. Note: MES Arpeggiator generates MIDI patterns. When used as a plugin, it controls other instruments (it does not output audio as a synth inside the AUv3 MIDI effect).
