    This one is for all the MIDI nerds like myself. Found this chart rather helpful today.
    Pitch bending a midi node (replicate slides) there are +8191 and -8192 values.
    Now as to know how or what value to use for certain bends. I made a chart to show you what values = what semitone intervals (12 in a Octave):
    1 semi-tone bend up would be 683
    2 semi-tone (tone) bend u would be 1365 etc.

    m2 - 683
    2 - 1365
    m3 - 2048
    3 - 2730
    4 - 3413
    tri - 4096
    5 - 4778
    m6 - 5461
    6 - 6143
    m7 - 6826
    7 - 7508
    oct - 8191

    Hope it helps anybody interested in MIDI programming

    pitch bend values play no articulating roll in multi sampled instruments (any longer).

    many sample libraries provide key switches or velocity layers (usually 120-127 value) for pitch bends and slide articulations.


    meaning, the pitch bend controller will probably only play as useful to synthesizers or sonically synthetic instrumentation.


    EXAMPLE:

    this first example is an actual bass articulation from trilian displaying; hammer-on (or note bend), slide down, slide up and slide up-down.

    this other example is midi data position displaying; pitch bend control and attempted slide which has a false articulation.


    as you can see/hear, even though the pitch bend parameter value's range is calculable, it doesn't detour the fact that this particular sound is much less desirable or useful (musically).

    there are much better sample libraries out there with fully articulated instruments that provide relative tone that is much more realistic.

    Forsure dude, but i haven't seen a chart like this, so i made it, and it helps alot if you doing Sine Wave kinda work.
    Thx for the clips, cant wait to get my hands on Trillian some day
    Thx Tim

    Like The Sine Wave trick, for low tunings, i just been playing around with it, with a Sine Wave Generator. Monophonic kinda stuff too
