Obscurium from Sugar Bytes is a virtual synthesizer that combines traditional oscillator shapes and FM synthesis to produce organic sounds, including spherical pads, bubbly arpeggios and strong percussion attacks. All parameters and motion lanes can be freely changed to create new sounds from the initial preset, which can be further enhanced utilizing the VST plug-in hosting feature.

Create complex, modular-like circuits and play it as a “one-finger-synthesizer” or access simpler patches for classical keyboard use. Draw Tools allow for inputting custom shapes, while Modifiers allow for changing all parameters simultaneously. A Super Obscure Mode can self-generate new sequences. Shift and Morph provide the possibility to rotate parameters and their motion lanes, resulting in an endless variety of connections, which in turn lead to organic and complex sound changes.

The Obscure Clock allows sequencer steps to be assigned to MIDI notes, playback speed and direction, which can change at any time, along with generating a different sound for each note of a melody, and creating tumbling rhythms, rolls, and triplets. The VST plug-in hosting interface can feed a VST instrument with trigger, pitch, and 11 automation lanes, allowing for extended functionality and new tonal possibilities within other VST plug-ins.
