Xen-Arts has released Xen-FMTS 2, a 4-Operator FM Synthesis with a specialized set of features for computer musicians interested in exploring the expressive possibilities of making music with alternative intonation systems. It includes 115 patches, 55 microtunings and 56 partials files.

Microtuning:

  • 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 intonation related sidebands in the timbre of the instrument.
  • Microtonal pitch-bend ranges may be configured in cents, harmonics and superparticular ratios.
  • Arbitrary microtonal pitch shifting makes it possible to easily pitch transpose the oscillators in both octave and non-octave increments.

FM-RM Oscillator:

  • 4 Operator FM Synthesis with Ring-Modulation.
  • 57 Operator Algorithms.
  • 11 different Operator Waveforms.
  • Analog Pitch Drift Emulator.
  • Transposition by cents offsets.
  • Partials text files may be used to quantize the frequency ratios of the operators to user specified values.
  • Velocity-to-Harmonics Modulation enables oscillators to dynamically sound harmonics of the fundamental pitch.

Modulators:

  • Seven dedicated hybrid modulators for Operators A, B, C, D, Filters, Amplifier and Pitch.
  • Each modulator includes an ADSR style envelope generator, and an LFO which can be switched to run at audio-rate.
  • Each ADSR Envelope Generator features Per-Stage Keyboard Tracking.
  • LFOs can either be synchronized to the host DAW tempo or set in Hertz. They include 24 Waveforms, a Slewer and can be switched to run at audio-rate.

Filter Section:

  • Pre-Filter Saturation Stage with 20 Saturation Types.
  • Two Independent Filters with Six Filter Types: LP4, LP2, HPF, BPF, BRF, APF.
  • One and Two Stage Filter Cascade.

Performance Control:

  • Full controller MIDI Pitch Microtuning with MTS (MIDI Tuning Standard).
  • MTS Support for both Single Note and Bulk Dump.
  • Loads MTS Microtuning Format Files Internally and Receives MTS Externally.
  • Local (Per-Patch) and Global Microtuning (Static Microtuning for All Patches).
  • Microtunings can be loaded from any directory on hard drives or storage devices connected to the PC.
  • 12 Note Polyphonic.
  • Monophonic Legato Mode.
  • Monophonic Portamento.
  • Microtonal Pitch Bend.
  • Vibrato.
  • Effects include Chorus, Lowpass Filter Cascade (Warm Filter) with 6 dB to 48 dB per-octave filters and Stereo Ensemble.

Price: Free.
