VAMono is a virtual analog monophonic synthesizer inspired by iconic monophonic analog synthesizers of the 80's. The oscillators are capable of wide variety of modulation to shape the sound before the filtering stage. Pitch, shape and pulse width can be modulated by LFO, ADSR envelope. Xmod and Ring modulation offers audio rate modulation. Hard Sync offers a characteristic sync sound. Filter section and Amplifier offers classic sound of the iconic analog synthesizer of 80’s. Amp section additionally offers amplitude modulation followed by distortion and delay effect. VAMono offers built-in 64 step sequencer to sequence notes and parameters. Synthesizer and Sequencer can be used as an AudioUnit Extension (AUv3) or Stand Alone. Stand Alone Mode supports Ableton Link, Bluetooth MIDI and MIDI IN/OUT.
