audio/din: Update to 60

Changes since 59:

DIN Is Noise 60:

  /*

    DIN60 is a binaural audio synthesizer which means you can hear
    binaural beats from the drones of the Microtonal-Keyboard or
    from the notes triggered when the balls of Mondrian hit a
    wall or ceiling or from the notes triggered by pressing keys
    on the Keyboard-Keyboard. Until DIN59, you could hear binaural
    beats only from the binaural drones of the Binaural Drones
    instrument.  That instrument is still available but this is
    a new and dynamic way to hear binaural beats!

    some say binaural beats are best heard on headphones.

    on the Settings screen,

      turn DIN Is Binaural ON or OFF.

      if you turn ON,

        every new drone on the Microtonal-Keyboard is a binaural drone.

          select the drone to change its binaural state, justification
          and separation from Menu > Drone Params > Modulation

        every new ball in Mondrian triggers binaural notes when it hits a wall
or celing.

          select a ball to change its binaural state, justification and
separation from
          Menu > Ball Params

        every key press on the Keyboard-Keyboard triggers binaural notes.

          set params for these binaural notes from the Settings screen itself.

    default Separation between L and R channels is 4 hz. if you turn ON ~ DIN
randomises
    the separation for each new drone or ball.

    if justification is Left, for a binaural drone or triggered binaural note at
T hz:
      L will sound T hz,
      R will sound T + Separation Hz
    if justification is Right,
      R will sound T hz
      L will sound T - Separation Hz,
    if justification is Random,
      well...

    this separation in Hz is heard as beats. so for a separation of 4 hz,
    you hear 4 beats a second.

  *\

  /*

    DIN60 intros a new way to make beats!

    a beat pattern envelops Voice or Noise, drones of the Microtonal Keyboard,
    triggered notes due key presses on the Keyboard-Keyboard, triggered notes
    due bouncing balls in Mondrian and the binaural drones of the Binaural
    Drones instrument. enveloping only some of these elements will be possible
in the
    next release :( , sorry!

    turn ON by clicking Beater button at the bottom left of any instrument. no
fader in this
    release :( , sorry!

    Press 5 to edit the beat pattern on the Beater editor or Menu > Editors >
Beater

    on the Beater editor, use the Beat Divider plugin to subdivide the beat
pattern to
    complicate the pattern.

    press SPACE to set end point of beat pattern. only available on Beater
editor and via
    this keyboard short cut only :(, sorry!

    use BPM tools to change the BPM, reverse, scrub, loop or pong the beat
pattern.

    BPM tools is also available on Voice FM/AM modulation editor.

    BPM modulation:

      press F4 to double the BPM.
      press F3 to halve the BPM.
      works on the Microtonal-Keyboard, the Beater editor and the Voice
Modulation
      editor only.

        doubling or halving BPM keeps the groove like octave shifting keeps the
melody.

        by default DIN uses 2 to multiply or divide the BPM. playing with BPM
this
        way reminds us of shifting octaves with notes! so why not multiply the
current BPM
        with other small whole number tuning ratios from key modulation to
modulate to,
        that is, produce other BPMs?  there is a 9x9 lattice of BPMs to choose
from
        based on various whole number ratios from 1..9.

      for ratios other than 2/1, say you choose the pair 3/2, 4/3 from the
ratios list and
      the current BPM is 120:

        an F4 press will multiply 3/2 to 120, to make current BPM 180, a BPM
thats
        a "perfect fifth" above 120.

        an F4 press again will multiply 4/3 to the 180 to produce 240. this is 2
times 120!
        that is, its a BPM thats an "octave above" 120, or in other words, a
doubling of
        the original BPM.

        an F3 now will divide 240 by 4/3 to give 180, a "perfect fourth" below
240.

        an F3 again will divide 180 by 3/2 to give 120! that is, we got back the
        original BPM which is a "perfect fifth" below 180 or an "octave below"
240,
        in other words, a halving of 240.

      this system combined with L, R delay line lengths (see below) in beats can
create very
      interesting, emergent polyrhythms!

      and also create isochronous binaural beats via Settings > DIN Is Binaural
:)

  *\

  /*

    in DIN 60, you set the L, R delay line length in beats @ the current BPM of
the Beater
    rather than in seconds.

    begin setting the values to small whole number beats. say L to 2 and R to 3
or 4,3 or 3,4
    or 6,5 etc. DIN uses the current BPM of the Beater to calculate the length
of the delay
    line in seconds. fractional beats are also welcome. set L to say 1.5 and R
to say 1.333333

    try setting the values at different BPMs of the beater!

    this combined with BPM tools (see above) can create very interesting,
emergent polyrhythms!

  *\

  /*

    new Levels panel on the Delay editor.

    use to change the level of the feedback and volume curves instead of
    manually picking and moving the curve by its vertices.

    move curves of both channels at once (feedback-both or volume-both)
    or one at a time (feedback-l, feedback-r, volume-l or volume-r)

    the slider lets you adjust the delay length of both L and R channels
    live. left end is 0% and right end is 100% of delay line length set
    on the Settings screen. experimental feature. may glitch depending
    on how fast you move the slider... :)

      an overhaul of Gravity

      as before, you can click and move the base or
      the tip of the gravity arrow to adjust its position,
      direction and strength.

      to (auto) animate the gravity arrow:

        assign a drone to base of gravity
        assign another drone to tip of gravity

        move or visual FM / AM modulate one or both these drones
        and gravity moves accordingly.

        animating gravity influences the trajectory of launched
        drones :)

      click 'Base to manual' and 'Tip to manual' to detach
      assigned drones from base and the tip respectively.

      you can now manually edit the base and tip again.

      click 'Select base', 'Select tip' or 'Select both'
      to select the assigned drones. Useful for moving,
      for visual AM/FM, to mute them etc.

      eg., you could mute the assigned drones by clicking
      'Select both' and then Menu > Drone Tools > Mute
