and well, at least -1 somewhat implies the inaudability of the fundamental here.Īnd to be fair, the high octaves are just as useless (if not more so) than the low octaves. The Virginia Tech link given on the cockos (Reaper) forum implies that it was arbitrary, but they also make some mistakes with the C4 bit, so I'm not sure how well researched that is.ĭepending on which kit you ask, middle C is either C4 or C5. Maybe though it came prior to MIDI in voltage controlled synths where you've got 60 cycles or 120 volts or whatever coming out of the wall - it may have to do with the midpoint of something like that as well? The lower end may provide ways to access LFO type waves or something.īesides, those really high sounds are annoying - it's more fun to play with a really low sound where the vibrations are breaking apart :-) I suppose, you could 'shift up' the frequency range an octave as your chart basically does, as we can't hear that lowest octave anyway, and we'd be out of our range on the top end an octave up.īut the range is probably because, if you have a saw wave at 10k, you're not going to really be able to hear the 1st overtone - so anything beyond 10k is going to sound like a Sine wave pretty much. E makes sense as the 64 (or 63 rough midpoint for 0-127) as it's midway between A (a 5th below) and C (a 6th above) as the lowest and highest notes on the piano. Hardware instruments in current production which support MTS include: Dave Smith Instruments (DSI) Rev-2, Prophet-12, Prophet-6, Oberheim OB-6, Moog Sub37, Minitaur, Novation Bass Station II, Peak, Sonoclast Plastic Pitch Plus, and the Waldorf Kyra.MIDI notes range from 0-127, from below our range of hearing (at 8 Hz!) to G9 at about 12.5 kHz:ġ28 units puts 64 in the middle - 'middle' C is about in the center of all that at 60.

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.
