Squosc is a VST effect plug-in freely inspired by "squareboxes".
When any material passes through Squosc's input, the constantly running oscillators are modulated via an envelope follower. Unusual oscillators inter-modulations and a series of "bend-buttons" offer a cheap and non-always-logic escape from traditional MIDI-note or pattern based composition. An example could be a drumloop turned into bleeping melodies, electric basslines, trashy drones, 8-bit style sweeps and other less-stable oddities. Squosc comes with 33 horrible presets for quick non-sense. When its input is silent, it doubles up as a tone generator.
Well know for a raw sound, "squareboxes" are usually processed with guitar amplifiers, filters, reverbs or whatever chain of effects. They often come unlabeled. Squosc makes no exception.
