Xenharmonic FMTS is a 4-Operator FM Synthesis VSTi with a specialized set of features for musicians interested in exploring the expressive possibilities of microtonal and xenharmonic music making.

Microtuning Features:

  • Internally loads and externally receives both MTS (MIDI Tuning Standard) Bulk Dump and Single Note Microtuning Files.
  • Operator ratios can easily be set to values that are coincident with the microtuning being used, thereby producing tuning related FM sidebands in the timbre of the instrument.
  • Isoharmonic spacing of the operator ratios.
  • Precise values may be set for microtonal pitch-bends.
  • Arbitrary microtonal period shifting makes it possible to pitch transpose in both octave and non-octave increments.

FM-RM Oscillator:

  • 4 Operator FM Synthesis with Ring-Modulation.
  • 57 Operator Algorithms.
  • 11 different Operator Waveforms.

Phase & Pulse-Width Oscillator:

  • 22 Waveforms.
  • Phase & Pulse-Width LFO Modulation.

Envelope Generators:

  • 6 independent Envelope Generators dedicated to modulating Operators A-D, Filters and VCA.
  • Velocity sensitive.
  • Keyboard tracking.


  • 2 State Variable Filters with 12 and 24 dB response.
  • Cutoff frequencies modulated by Velocity, Envelope Generator, LFO and Keyboard Tracking.
  • Low Frequency Oscillators can be set to modulate the cutoff frequencies of the filters at audio rates, thereby producing sidebands in the signal.


  • Saturator for subtle to extreme distortion.
  • 6 dB LPF Warm Filter.
  • 4-Voice Stereo Ensemble Detuner.
