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.
  

Filters:

• 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.
  

Effects:

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