VAPolyTZFM
Polyphonic TZFM Synthesizer

















VAPolyTZFM is polyphonic synthesizer featuring Through Zero FM, which is a type of linear frequency modulation and it is capable to maintain the pitch therefore it can deliver more musical results.
VAPolyTZFM 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.

Synthesizer
The synthesizer features Through Zero FM. It also features two oscillators, 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.
