audio/din: Updates to 51.1

Changes since 50.2:

DIN Is Noise 51.1:
  * improved DIN font *
  ! fixed drone arrow defaults save/load !

DIN Is Noise 51:

   + drone is anchored or launched on creation
      anchored means stays fixed at the place of creation
      launched means 'flies' off based on its velocity and gravity
        try with Menu > Drone Tools > Add / Wand
      set at Menu > Drone Params > Defaults

  + set velocity +/ acceleration vectors of drones to presets via Menu > \ 
Drone Params > Motion > Set velocity/acceleration
    + presets are +ve or -ve vertical, horizontal, velocity, acceleration and zero

  + auto flip (clock < > anti-clock) auto rotating velocity/acceleration \ 
vectors every some degrees
    + via Menu > Drone Params > Auto flip > Set / Unset / Toggle
    + default 'every some degrees' is 90 degrees

  + gravity
    + presets for gravity vector
       0, left, right, up and down
    + gravity tracks mouse position
      + click Gravity > Mouse
    + gravity tracks the first among selected drones
      + click Gravity > Drone
        ! as drone selection changes, gravity may track a different drone !
      - removed Menu Drone Params > Track gravity

  + mesh polygon filling per drone color

  * color of a launched drone is same as color of the launcher
    * try changing color of the launcher as drones are launched

  * changed color of velocity/acceleration vectors to move away from green (used \ 
for selection) and red (used for errors)
    * cyan = color of velocity vector of all drones
    * (reddish) magenta = color of acceleration vector of all drones

  * changed arrow visualisation of velocity +/ acceleration vector of all drones
    * Head
      * edit the position of the arrow tip
        * can go 'above' the vector tip ie > 1.0
        * can go 'below' the drone location ie < 0.0
        * can be on the body ie 0 <= tip <= 1.0
    * Shoulder Position
      * edit position of the arrow's shoulder tips
    * Shoulder Width
      * edit width of the arrow's shoulder
    + Cap or Decap the arrow

  + set default arrow head, shoulder position and width, cap from Menu > \ 
Drone Params > Defaults
    + used when adding & wanding drones
    + change existing drone's velocity/acceleration vector arrow params via Menu \ 
> Drone Params > Visual

  + improved geometric chuck
    + on a chuck with N drones, the first N - 1 drones have trail set to 0
      + the last drone has trail set to 10000
    + toggle auto reset trails
      + Menu > Drone Params > Chuck > Auto reset trails
    + 2 changes above aid visualisation and experimentation instead of manual trail
      resize/reset every time after changing a chuck param
    + toggle chuck outline
      + click Menu > Drone Params > Chuck > Draw chuck outline
      + aids screenshotting
    + chuck outline drawn per drone color

  * default scale/rotate drones center to microtonal keyboard center

  * default selected range to C Eb

  + mouse wheel on microtonal keyboard to scroll along horizontal
    + press SHIFT and scroll to scroll along vertical

  * short form of echo command is .

  * improved bpm handling of drone pendulums and meshes

  * improved drone trail handling/display

  * close menu after setting modulation direction

  ! fixed bug in zoom of curve editor when mouse slider is active !
  ! fixed draw crosshairs on drone mesh preview !

audio/din: Updates to 50

Changes since 49.1:

DIN Is Noise 50:

  /* Wand drones into existense using Drone Tools > Wand

    /* tool toggles between Add and Wand modes

    /* In Add mode (the only mode until DIN49.1), you add a new drone by
       left clicking on the microtonal keyboard. You click and drag to
       'spray' new drones.

    /* In Wand mode (new in DIN 50), you simply wave the mouse to add drones on
       the microtonal keyboard. Use the Wand distance (Drone Params > Defaults)
       to control how close or spaced out the drones are to each other.

  /* new Drone Params > Defaults tab to set defaults for some drone parameters:

    /* wand distance - distance to move the mouse before DIN adds a drone in \ 
Wand mode.

      ! smaller distance means drones are created close together
      ! larger distance means drones are more spaced out

    /* type of drones wanded/added:

      1. immortal - drone forever until deleted << default and the only \ 
type until DIN49.1
      2. mortal - die after their lifetime << drones launched from another \ 
drone are this type
      3. reincarnate - die after their lifetime only to be (re)born immediately! \ 
<< new to DIN 50!

    -> type of sound made by drones:

      -> moved from Drone > Tools in DIN 49.1
      -> drones a pitch/volume
      -> noise @ pitch/volume

    -> Drone rise (min, max), fall (min, max), lifetime and handle size.
      -> rise, fall times moved here from Settings screen

  /* Drone Tools > Immortalize to make drones immortal
  /* Drone Tools > Mortalize to kill drones after their lifetime
  /* Drone Tools > Reincarnate - drones rebirth after their death, immediately!

  /* Auto rotate Velocity or Acceleration or Both of selected drones from
     Drone Params > Motion tab
     /* @ RPM
     /* Clockwise or Anti-clockwise
     /* Start, Stop or Toggle

  /* Set AM and FM directions to
    /* Vertical, Horizontal, Velocity or Acceleration
    /* Until DIN 49.1:
      /* AM direction = Vertical
      /* FM direction = Horizontal

    !
      interesting fx possible via auto rotating velocity +/ acceleration and \ 
using them
      as modulation directions. also interesting to launch drones from auto rotating
      velocities.
    !

  /*
    DIN 50 introduces a virtual geometric chuck inspired by the geometric chuck,
    a drawing machine from the 19th century! DIN's chuck, made with a bunch
    of drones, not only draws (via drone trails) but also sounds notes
    (via snapping), drones or noises!

    To begin, select a bunch of drones and
      choose Drone Tools > Chuck
        DIN creates a geometric chuck with these drones
          Minimum 2 drones
          Good start = 3 drones
          Each drone rotates about the other
          1st drone is central, rotates about nothing, so stays still
            You can move this drone around and move the whole chuck
              The 2nd drone rotates about the 1st,
                The 3rd drone rotates about the 2nd,
                  and so on

          Browse the selected drones of the chuck with Drone Tools > Browse drone
          or press <- and -> to select a drone in the chuck and

          Adjust the speed at which this drone rotates about the other
          (Drone Params > Chuck > Speed), the distance at which it rotates
          (Drone Params > Chuck > Length), flip the direction of rotation
          (anti-clockwise < > clockwise) (Drone Params > Flip), pause/go
          (Drone Params > Chuck > Toggle) the rotation and draw a trail
          (Drone Params > Chuck > Trail length). Recommend trail on the last
          drone of a chuck to make drawing like the real geometric chuck

          Set Angle per frame to speed up (large angle) or slow down (small \ 
angle) the rotation
          of all the drones of (all) chuck(s).

          The drones of the chuck sound the pitch/volume they are on the \ 
microtonal keyboard.
          You can mute/unmute any / all of the drones of the chuck.
            Drone Tools > Mute, Drone Tools > Unmute
          You can convert any / all of the chuck's drones to noise (Drone Tools \ 
> Drone > Noise) or
          vice-versa.
            Drone Tools > Drone 2 Noise, Drone Tools > Noise 2 Drone
          You can snap drones of the chuck to sound notes
            Drone Params > Motion > Snap drones to notes > Set

  *\

  + stop drone decay (and death) if frozen
  + retime decay time of deleted drone(s) if you select drone(s) and delete again

  * change FM depth (like AM depth) by moving along vertical on mouse slider
    * moved along horizontal until DIN 49.1
  * change FM bpm (like AM bpm) by moving along vertical on mouse slider
    * moved along horizontal until DIN 49.1
  * helps with moving drones along circular paths at different speeds
  * improved value spinner UI
  * improved find_nearest_note (..) performance
  * improved drone trail performance
  * improved console text & value display

DIN Is Noise 49.1:

  ! fixed : crash from 'delays' editor when menu toggled and plugin browser fold \ 
toggled !
  /* multiple channel MIDI support

Log message:
audio/din: Updates to 49

Changes since 48:

DIN Is Noise 49:

  /* position (instead of modulation until DIN48) affects velocity vector of drones

  /* Set center for rotation and scaling of drones:

    Menu > Drone Tools > Auto Center uses average center of selected drones
    Choose Menu > Drone Tools > Set to mouse and Click on it to set center to
    point under mouse cursor. Click to stop.
      You can also click and just move the magenta cross that marks the center

  on mouse slider:

  /* warp mouse position when rolling wheel
  /* press / to toggle warp mouse at boundary

  * improved the drone selector / drone mesh/pendulum preview on microtonal keyboard

  * show hz/vol for selected drones only (instead of all drones until DIN48)

  ! fixed: flip (using ` key shortcut) between instruments loads the correct \ 
editors !

  EXPERIMENTAL:

  /*  when scaling or rotating drones, change scale or angle increments using \ 
mouse slider (see
      DIN 48 CHANGELOG below for how to do this) to change scaling +/ rotation \ 
'speed'

  /* press f to toggle paint harmonics (or phase) in Sine_Mixer

  /* overlay last screen (instrument or editor) on curve editor

  /* !EXPERIMENTAL! mouse slider increment scaling

    When using mouse slider:

      press , to set increment to 1/N of original increment
      press . to set increment to Nx of original increment
      press 1,2,3...9 sets N = 1,2,3...9
      press 0 to set N = 10
