Ping-Pong / Bounce option for parameters animated by FFT

[dreamaticos]

Currently when a parameter is animated by FFT you currently have 4 options: Forwards, backwards, increasing or decreasing. Occasionally I've found myself thinking it would be nice if when choosing +/- , you could also choose what to do at the end of the parameter, either loop or pingpong.

So rather than it going 0->100->0->100->0
We could get 0->100, 100->0, 0->100

Currently I managed to do this with envelops. Might be easier with the same playback control as say a timeline or BPM controlled parameter.
