Linear, quadratic and cubic interpolation

[tulamide]

Since it is very abstract, I'm working on a sophisticated example. Meanwhile, if you're familiar with interpolation or able to understand it from the schematic, you might want to add these 3 modules to your toolbox.

If you take a closer look at the math, you will see that all modules only use addition, subtraction and multiplication, which means you could do a dsp code version from it and feed the t-value with a [0,1] mapped oscillator. You'd then have a vivid, dynamic base with four poles (in case of cubic interpolation) for whatever you want to modulate with it. Just a thought...

It would be good to add some streamy interpolation stuff to Exo's works too.
