X*ONE

X*ONE free software-synthesizer by Alterex

X*ONE is a free software synthesizer developed by Alterex. Available format(s): VST for Windows.

X*ONE is a virtual monophonic synthesizer with one oscillator, one modulator, and one 12dB lowpass filter. Although the design is similar to Alterex’s ViCON the sound of this module is described as “phatter”. 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.

Features:

  • 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.
