What is the pitch bend's unit of measurement in the the midi clip editor?

Wondering if anyone knows, or where I might find information about, the unit of measurement in the pitch bend view of the midi clip editor?

    Pitchbend is 14 bit data.  16384 possible bend positions.  8192 on the bend up, and -8192 on the bend down.



    How the device receiving the pitch bend data will react to it is dependant on it's settings.  Some synthesizers can alter the range of pitchbend.  Ableton's Analog, for example, can be set to a maximum bend range of 12 semitones.  Other instruments, such as Serum, Sylenth1, and Omnisphere, allow for up to 24 semitones of pitch bend.

    If it helps, Ableton's instruments (e.g. the "Analog" synths) seem to have +/-6 semitones as the range of their pitch bend (for an octave range overall)

    So you can in theory divide 8192/6 to get 1365 for a semitone, and multiply that by the number of semitones you want to bend:

    1365 = semitone

    2731 = tone*

    4096 = minor 3rd

    5461 = major 3rd

    6826 = perfect 4th

    8192 = tritone

    * I have found that this, for some reason, is slightly out of tune, and bending by 2783 seems more precise. YMMV

    Ableton presumably divides semitones into cents internally for convenience (approx 137 divisions to a cent), rather than doing true proportions of the octave, as otherwise the above amounts would sound quite out of tune when working with equal-tempered synths.
