VAPolyMk3
Multi Synthesis Synthesizer


















VAPolyMk3 is a multi synthesis polyphonic synthesizer for iPhone, iPad and Mac. Inspired by the last generation of classic analog synthesizers in the late 1980’s such as Oberheim Matrix series synthesizers, It offers Subtractive Synthesis and modular FM Synthesis. It operates as a stand alone or as an AudioUnit Extension (AUv3). Stand Alone supports Ableton Link, MIDI and audio file export.

Synthesizer
Oscillator Section features 3 Oscillators and 3 Modulation Oscillators. Each Oscillator has envelope and amplifier. Oscillators can be routed for Subtractive Synthesis and FM Synthesis. Signal from Oscillators are routed to mixer, resonant low pass filter, resonant hight pass filter and amplifier. The synthesizer also features two ADSR envelopes per voice, two LFO and analog style sequencer.

Effects
The Effects include delay, chorus, flanger, reverb, eq and compressor.

Sequencer
The sequencer features piano roll and parameter automation editor to program 16 bar pattern per clip.
Main Features

Others
- Support MIDI 2.0. Support Foot Pedal (CC#11, CC#64) and Per Note Control.
- Support iCloud Drive.
- Support Ableton Link, Bluetooth MIDI, MIDI In / Out.
- Support Audio Unit Extension (AUv3)
Works on iPhone, iPad and Mac.
System Requirements
- iOS 17 or later
- macOS 14 or later
- This app requires a lot of CPU power. 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, turn Anti-Aliasing-Option off or reduce number of voices.
- AudioUnit Extension (AUv3) requires host application which support AudioUnit Extension.
- AudioUnit Extension (AUv3) is supported by Apple Garage Band on iOS and macOS, and Apple Logic on Mac. For any other DAW, it depends on the application and some of them don’t support AudioUnit Extension (AUv3).
