Polyphonic Synthesizer
VAPolyLoop features lowpass filter and amplifier which are optimized for playing by step sequencer. VAPolyLoop contains polyphonic synthesizer and analog style step sequencer. 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. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac.
Synthesizer
The synthesizer consists of three oscillators, resonant low pass filter, amplifier, distortion effect and five LFO.
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.
