Pecheneg FX has recently released Pecheneg Tremolo, a free tremolo effect plug-in for Windows.
The Pecheneg VST plugin is a tremolo effect, which has the possibility to adjust the shape of the tremolo modulating curve and to synchronize the frequency with a host, or set it manually.
When synchronizing with a host (Tempo: host), the tremolo frequency is adjusted by the knob, which sets the modulation period, while the note type (regular, dotted or triplet) can be selected below the knob. When set manually (Tempo: man), the tremolo frequency (in Hz) can be set directly with the knob.
The Shape, Phase and Symm knobs set the wave form of the modulation, with the amount of modulation set by the Depth knob.
Pecheneg Tremolo is free to download for Windows (VST).
