Stepcomb is a stereo comb filter vst effect. The frequency of the comb filter is controlled by a step sequencer with pitch and octave.There is also a standard SV filter before the comb to control the sounds (which can sometimes be very brutal). There is a cv sequencer which can effect the comb pitch and/or the filter cutoff. A noise oscilator can be used to excite the signal and an HPF (postfilter) can remove unwanted bass frequencies.When processing a stereo track, the right comb can be offset by octaves or semitones. This plugin uses some parts from the forthcoming synth "groove modulator" such as the step sequencer, shuffle clock and the randomiser. The step sequencer section is designed to be transferable between projects so if youre synth needs a sequencer, grab the source files to stepcomb and copy and paste.
