Simple-Media Spook Keys VSTi

Simple-Media has updated Spook Keys, a freeware VSTi designed to re-create the sound of a ‘Theramin’ and offering control either using a MIDI keyboard or using the mouse to drag the glowing spot across the ‘chart’ for more authentic ‘Theramin’ style play.

In the updated version the x/y controller does not spring back to its start position when the mouse button is released. This makes indefinitely held notes without having to hold the mouse possible.


  • sine, sawtooth, triangle and pulse waves
  • variable key in and out response
  • variable LFO for vibrato and tremolo
  • pan, chorus (detuning), stereo spread and glide controls
  • filtered, ping-pong, stereo delay
