Turning my gesture synthesizer into an articulation engine tonight :)

The core data structure that powers Gest is what I call a "ramp tree". This provides rhythmic subdivisions of a beat.

How it works is: a phasor (periodic ramp signal) goes into the tree, and then this phasor signal is dynamically resynthesized and sped up / slowed down based on the structure of the tree. What comes out the other side is a series of 0-1 ramps of varying length relative to the input phasor.

Normally, the output of the ramp tree is used to interpolate between to values like you would a line segment. However, if you skip that step and just use the ramp tree output, you can use this as an envelope signal!

The ramps output by the ramp tree aren't always linear. Behaviors are functions that can be applied to the ramp to rescale it. This allows things like exponential line segments to happen.
