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.
• Two external inputs.
• XY joystick.

Added features:

• Polyphony up to 6 voices. Total control of the polyphony features with the extended KXMOD system.
• Each voice can be controlled with relative parameters (KXMOD).
• Analog sequencer (CV & gate) with a memory of 256 CV and 256 gates, files saved on disk, 2 accent lines, random clock, keyboard input to transpose or to record the CV.
• Mini knobs to adjust each matrix modulation, 0 to 1.
• Modern skin with notepad and variable color background.
• Html help file.
• You can adjust the response curve of the oscillators.
• The original ASR (trapezoid) is extended to 2 ADSR with Attack Reset mode, Host and internal sequencer synchronization.
• Delay fx with host synchronization and LFO modulation. It replaces the original spring reverb.
• LFO, Sample & Hold and third ADSR envelope added, monophonic modulations, they can replace the external inputs (In1, In2).
