VAPolyLoop vs MES Arpeggiator

VAPolyLoop features lowpass filter and amplifier which are optimized for playing by step sequencer. VAPolyLoop contains polyphonic synthesizer and analog style step sequencer. The synthesizer consists of three oscillators, resonant low pass filter, amplifier, distortion effect and five LFO. VAPolyLoop operates as a stand alone or as an AudioUnit Extension (AUv3) for iPhone, iPad and Mac. Stand Alone supports Ableton Link, MIDI and audio file export. Built-in Effects include delay, chorus, flanger, reverb, eq and compressor. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac. Main Features Polyphonic Synthesizer. Lowpass filter modeled on diode ladder filter. Distortion Effects Analog style step sequencer. Maximum 8 voice polyphony. it depends on performance of the device it is running. Built-in effects and piano roll sequencer. Audio Export. Linear PCM format (AIFF, WAV and CAF) and compressed format (AAC) Support Audio Unit Extension (AUv3). Support MIDI 2.0. Support Foot Pedal and Per Note Control. Support Ableton Link, Bluetooth MIDI, MIDI In / Out. Works on iPhone, iPad and Mac. Support iCloud Drive to share project files between the platforms. Full Factory Preset: 96, Effect: 40 Improvements Support MIDI Foot Pedal (CC#11, CC#64) MIDI CC Settings are saved. It will be recovered when the app launched in the next time. UI Color can be selected from black, navy or gray. System Requirements iOS 17.0 or later Devices with Apple Silicon are recommended. A13 Fusion or above is highly recommended. if sound is distorted when using a device with less CPU power, reduce number of voices. AudioUnit Extension (AUv3) requires host application which support AudioUnit Extension. AudioUnit Extension is supported by Apple Logic and Apple Garage Band on iOS and macOS. For any other DAW, it depends on the application and some of them don’t support AudioUnit Extension.

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).
