Pluggotic has released Squosc and Footile. Both are free and available for Windows as VST effect plug-ins.
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.
Footile is the remix of a VST effect by Novuzeit, Motile. Motile and Footile share the same serial-multi-fx concept and sound architecture but with a different modulation system.
In Footile, the effects parameters can be tweaked on four different "scenes". Each scene is shown (colour coded) as a corner of an XY pad in the middle of the interface, so moving the cursor will morph each scene into the others.
Furthermore, morphing can be modulated with independent and mixable LFOs, sequencers, envelope followers, randomizers (s/h), operating on X or Y axis or both at host-synchronized rates.
Inspired by a certain quest for failure, Footile can be pretty unsubtle. It will treat signals with the following FX chain: pitch shifter-bitrate crusher-psycho-grains-glitch-metal-filter-control. Every effect can be deactivated and mixed at will.
Footile comes with 32 "unsuccessful" presets.
