Vinylusion has 4 main controllers:

  • MEKANIKX gives you the option to tweak the more mechanical and machine-like background noises of a turntable.
  • T-TABLE A and T-TABLE B are to be used mainly to generate and adjust vinyl crackles and pops.
  • STATIKX is a noise oscillator.

unstable is a free pitch shifter VST plugin developed by de la Mancha. Compatible OS(s): Windows.

unstable likes to mess around with your audio pitch, with 3 subtle pitch modulation modes to simulate the unpredictable but lovable pitch instability of an old tape machine or analogue equipment. It doesn’t only do subtle though, you can also put it in ‘insane’ mode if you’d rather just FSU.


  • 3 modes of continuously random pitch modulation:
    1. Buzz – rapid, fuzzy modulation.
    2. Wobble – medium, jerky modulation.
    3. Drift – slow, gentle modulation.
  • Adjustable frequency and level for each modulation mode.
  • Master level mode to adjust overall subtlety of effect.
  • Wet / dry mix level control.
  • Insane mode – removes all subtlety and smacks your pitch up.
  • All controls mapped to MIDI CC values.
