This basic unit has some tricks up its sleeve and is one of the core parts of Alterex’s X*PAND VSTi – that will be released next year.


  • Modulator: low frequency oscillator and envelope generator (tempo synced).
  • Oscillator: saw, square waveform and manual pulse width control.
  • Filter: 12 dB lowpass filter with dedicated envelope modulator.

WTComp free compressor by Plektron

WTComp is a free compressor VST plugin developed by Plektron. Compatible OS(s): Windows.

WTComp is an analogue tube compressor. It distinguishes itself from a common compressor due to its simple use. The only thing you have to do is to set the warm-level (compression) instead of going crazy with dozens of parameters.

WTComp is based on the parallel compression technique that maximize the output signal rather than destroy the sound’s dynamic. The tube simulation makes the sound warm and loads without distortion, processing a “fat” wave without square peaks.

The advanced internal structure includes an intelligent audio-clip system.

It is deal for mastering and use on single tracks.
