VAPolyMk4

Polyphonic Synthesizer

VAPolyMk4 is bi-timbral polyphonic synthesizer, which features output morphing, classic ring modulator and global offset parameter control. VAPolyMk4 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

Each synthesizer consists of three oscillators, resonant  low pass and  hight pass filter, amplifier, three envelope generators and two LFO. Two synthesizers can be configured as layer or split.

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.
