StepCut

StepCut is a free filter VST plugin developed by WOK. Compatible OS(s): Windows.

StepCut is a dual-modulated multi-filter. The cutoff of an LP/BP/HP-filter can be controlled by an LFO and/or a step sequencer. The step sequencer can also control the speed or the modulation amount of the LFO. Both are synced to host. The LFO can also run at audio rates (manual or by incoming MIDI notes). If all this is not enough: both LFO and step sequencer can send their values as MIDI CC messages to control other plug-ins or synths.

STC-3 stereo width control

STC-3 stereo width control is a free stereo imaging VST plugin developed by RAZ Audio. Compatible OS(s): Windows.

The STC-3 is a precision tool for controlling the stereo width of any stereophonic content.
Use it for expanding the stereo field of synth pads, sound effects or soundscapes or to narrow a track to full mono.
Designed for zero artifacts and natural sound, the STC-3 can be used on a single channel or on the bus processor, for both mixing and mastering.

A large stereo-readout display provides a visual feedback of the used expansion and the dedicated ‘LF Processor’ makes sure that the low frequency content is kept vivid and tight, albeit the stereo expansion.

For further details, we invite you to read the manual.
As all ‘Raz Audio’ processors, the M/S controller is available as a free download.

Star Cym is a free drum machine VST plugin developed by xoxos. Compatible OS(s): Windows.

Squosc

Squosc is a free glitch VST plugin developed by Pluggotic. Compatible OS(s): Windows.

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.
