I would love to see LFO?s in Blender , even as a python script, Do you know what LFO?s are ?
Well a LFO is a Low Frequency Osilator.
An Oscilator is Something that is Going from one place to another back and for over time.
Like this waveforms, but oscilator nowadays are more than a simple monotone sinewave, maybe this is not to useful to character animation but for other musical stuff would be great.
This would be used in the ipo’s
Also some kind of ipo modifiers, to make bouncy fx, or preset types of ipo’s more than just bezier,line or constant.
