Software plugin instruments which support MTS include Native Instruments FM8, Synthogy Ivory, and Xen-Arts' various xenharmonic VSTi plugins, including the FMTS FM synthesizer, Ivor virtual analog synthesizer, and XenFont SoundFont sample player.

Software which supports MTS includes Scala, TiMidity++, ZynAddSubFX and FluidSynth. The precision pitch values may be used in microtonal music, just intonation, meantone temperament, or other alternative tunings.

These parts are exactly 100/16384 cents (approximately 0.0061 cents) in size, which is far below the threshold of human pitch perception and which therefore allows a very accurate representation of pitch. This higher resolution allows a logarithmic representation of pitch in which the semitone is divided into 128 2 = 2 14 = 16384 parts, which means the octave is divided into 196608 (logarithmically) equal parts. Effective resolution = 100 cents / 2 14 =. The next two bytes (14 bits) specify the fraction of 100 cents above the semitone at which the frequency lies. The first byte of the frequency data word specifies the highest equal-tempered semitone not exceeding the frequency. The frequency range starts at MIDI note 0, C = 8.1758 Hz, and extends above MIDI note 127, G = 12543.854 Hz. 'Frequency data shall be defined in which are fractions of a semitone. The frequency data format allows for the precise notation of frequencies that differ from equal temperament. If ƒ is a frequency, then the corresponding frequency data value d may be computed byĭ = 69 + 12 log 2 ⁡ ( f 440 H z ). 6.2 Microtonal music software supporting MTS.
