VAMono is a virtual analog monophonic synthesizer inspired by iconic monophonic analog synthesizers of 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.
VAMono features two digital oscillators which are capable of generating continuously variable wave shapes from triangle, saw to square. Oscillator 1 also generate sub for deep bass sound. Variety of modulation can be applied to shape the sound before the filtering stage.
Filter and Amplifier
The Filter and Amplifier are virtual analog and inspired by an iconic analog monophonic synthesizer of 80’s and inherit the characteristic behavior. This filter and amplifier are unique and different from conventional filter and amplifier and produces distinctive sound.
VAMono features 64 step sequencer to sequence notes and parameters. Loop length can be set from 1 bar to 4 bars. This sequencer can output MIDI to control external devices.
