Control Effects

    Controller Effects are embellishments that are applied to control signals.

    Toggle and Hold

        The toggle and hold object routes one input signal to one of two outputs.
        When the input signal changes, it is routed to the output that was <i>not</i> 
        used last time. Several toggle and hold'sconnected in a tree formation will 
        route the newest input to the least recently used output.

    Up Down

        If the current value is greater than the previous value, route to top output.
        Otherwise route to bottom output.

        Interesting to chain several of these together in a tree structure.

    Sort_2

        Compares two values and routes the higher value to the hi output, the lower
        value to the lo output. Several of these objects connected in a matrix results
        in an N input bubble sort.

    One Shot

        Use the One Shot to generate a single square wave with a specified duration.

        input
        T   time            Duration in seconds
        sr  start/restart   starts or restarts the timer

        output
        b   busy    active when the one shot is active
        d   done    toggles when the timer is has finished

    Slide And Hold

        Use the Slide and Hold component to get from x0 to x0+dx in T seconds.
        When triggered by sr, the input value is held and a linear ramp applied to it.
        The final value is held until .

    Fade In Out

        fade in out generates a multistage envelope

        Wait for e to go negative
        Spend r1% of T fading in and be at the value X by time T
        Wait for e to go positive
        Spend r2% of T fading out

        T is the frame time

            +_                  _________
        e in  |                |
            - |_________{...}__|

        X in  X      ___{...}___
                    /           \
                   / |         | \
        = out 0___/  |         |  \_____0
              |   |  |         |  |   |
              |   |  |         |  |   |
        e out |   |  eee{...}eee  |   | in hold
        f out |   fff           fff   | in fade
        g out gggggggggg{...}gggggggggg active
              |      |         |      |
              |<--T->|         |<--T->|

    Vibrato

        Use the vibrato object to 'shake' an input value after a period of time.
