VAPolyTS
Polyphonic Synthesizer
VAPolyTS is polyphonic synthesizer for iPhone, iPad and Mac. It is inspired by the synthesizers which contributed to shape iconic sounds of Trance, House and Techno Music in 1990’s. It operates as a stand alone or as an AudioUnit Extension (AUv3). Stand Alone supports Ableton Link, MIDI and audio file export.
Synthesizer
The synthesizer features two stack oscillators. The one of them can generate mix of detuned seven oscillator outputs. The other one can generate mix of several octave shifted oscillator outputs. It also features a mixer, a resonant low pass filter, a resonant hight pass filter, an amplifier, two envelope generators, two LFO and analog style step 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.

System Requirements
- iOS 17 or later
- macOS 14 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.
