KX-Synth-X16 is a virtual analog modular synth plug-in based on the EMS VCS3 structure, but with some additional features.

Common features with the VCS3:

  • Three variable shape oscillators, tweaked to simulate the color and bandwidth of VCS3's oscillators.
  • 16*16 pin matrix with feedback connections.
  • LP filter, 18 db per octave with self oscillation.
  • Noise generator with EQ.
  • Ring modulation.

  • Mini knobs to adjust each matrix modulation, 0 to 1.
  • Modern skin with notepad and variable color background.
