IO Singularity is a virtual analog synthesizer designed to deliver rich and dynamic sounds. It features two oscillators, each offering a variety of waveforms including saw, sine, triangle, square, and noise for the second oscillator. This combination allows for a wide range of tonal possibilities, from classic analog warmth to more experimental textures.

The synth includes a selectable sub-oscillator that adds depth and fullness to the sound, enhancing the overall sonic character. Its ADSR envelope provides precise control over the amplitude, enabling expressive shaping of each note. Additionally, the instrument offers a choice between low pass and high pass filters, each equipped with a dedicated attack parameter for refined tonal sculpting.

Filter cutoff modulation adds another layer of expressiveness by allowing control through the attack generator or velocity, both of which can be selected to suit the player’s preferences. This modulation flexibility supports dynamic performance and sound design, making IO Singularity a powerful tool for musicians seeking to craft unique synthesizer sounds.
