  Gater is now called Beater in preparation for the new beat engine in DIN (still WIP
  as of 59)

  edit beat pattern in beat pattern editor
    press 5 from microtonal-keyboard or Menu > Editors > Beater
  new beat patterns in the library
  use 9 and 0 keys to go thru beat patterns

  in the beat pattern editor:

    press F3 to halve current BPM
    press F4 to double current BPM
    press F5 to shift key up an octave
    press F6 to shift key down an octave

  on the microtonal keyboard:

    press F3 to halve current BPM
    press F4 to double current BPM

in a curve editor:

  /*

    increase/decrease size of tangent of a curve

    click+pick a tangent of a curve and press f or Menu > Tools > Size tangent
    and just mouse up and down to size tangent

  *\

  /*

    pin / unpin vertices & tangents of a curve in a curve editor

    choose Menu > Tools > Pin / Unpin
    and click+pick a vertex or tangent. ESC to stop.

    or click-pick a vertex or tangent and press p to pin/unpin. click to stop.

    why pin?

      pinned vertices and tangents dont rotate when curve rotates.
      pinned tangents dont move when their vertex moves

        try it on shapeforms!
        watch fft!

* changes to default parameters in binaural drones instrument
  * start pitch is 128 Hz
  * justification is left
  * scale notes at C D G B when C = 128 hz (if A = 432 Hz)

* default tuning is pythagoras for all instruments
  * tuning is global ie applies to all instruments

* Menu > Tools > Fold tangents with Selection only ON, folds just the selected tangent
  and if you select a vertex folds both its tangents

* improved delay lines
* optimised handling of parameter spinners in UI *

* boxes not filled by default in Mondrian

:( mouse returns to last position on all screens :)
:( bug asked user to select drones when no drones were selected and drone volume change was attempted :)
:( fixed bug not saving inner, letter and word spacing curves on morse code module :)
:( fixed fold tangents only folding tangents of the selected vertex then stopping, instead of offering
   to fold other tangents until canceled by user :)
