VAPoly
Polyphonic Synthesizer
VAPoly is a virtual analog 8 voice polyphonic synthesizer for iPhone, iPad and Mac. VAPoly features built-in effects, built-in sequencer, parameter automation and oscilloscopes. VAPoly can be used as a stand alone or as an Audio Unit Extension (AUv3). Stand Alone supports Ableton Link, Bluetooth MIDI, MIDI IN/OUT and audio file export. Project files can be saved in iCloud Drive, so that you can work on a project on iPhone, iPad or Mac whichever is convenient for you at the time.
Synthesizer
The synth features two oscillators, two ADSR envelopes, a high pass filter, a low pass filter and an amplifier per voice. The oscillators are capable of wide variety of modulation to shape the sound. The low pass filter is modeled on cascaded OTA filter circuit for classic analog sound.
Effects
The Effects includes delay, chorus, flanger, reverb, eq, and compressor.
Sequencer
The sequencer allows you to program 16 bar pattern per clip and you can have total 16 clips.
