Boids Delay

Algorithmic Granular Delay.

The Boids plugin is a hybrid Granular + Delay plugin that features a 2D "Boid"
swarm as a set of modulators for the grain and delay parameters.
This plugin grew out of an interest to accomplish two different goals:

1 - Finding a way to manage grain swarms visually.
2 - Creating delay-based ambiance that has subtle, not quite random, variations.

The Boid Swarm represents a set of flocking boids:
a boid is a "Bird Android" - see Craig Reynolds work:


There are a few simple rules that each boid uses to determine where it will fly
to on the next swarm advance. These include rules for how fast to fly, how near
to fly to other boids, how strongly to move to the center of the flock,
how strongly to follow a leader boid, and how strongly to match the position and
direction of nearby boids.

The swarm space that the boids fly in is treated as a 2D coordinate system where
the X (horizontal) and Y (vertical) position of each boid can be used to modulate
controls. A swarm may contain up to 200 boids.

The plugin supports multiple grain streams and multiple delay taps (up to 200 each).
Each grain stream and delay tap is associated with one of the boids in the swarm.
The X position, Y position, Radius position and ID number of that boid associated with
the grain stream or tap can be assigned to modulate the controls that define how that
specific grain or tap will be produced.

For example, the X position of a boid can be assigned to control the pan value for
the delay taps. For each delay tap, the X position of the boid associated with that
delay tap will determine its pan position in the output stereo field. Different taps
will have different pan values depending on the location of the boid associated with
the tap. In this configuration delay tap signals will move through stereo positions as
the boids move through the swarm space.

Each of the parameters for the grain streams and delay taps can be modulated using the
position of the boid associated with the grain/tap (and/or traditional LFO modulators).
