Analog Granular Synthesis Prototype

The "Fragments" are a set of pings, or short bursts of sound created by a trio of Twin-T filters.
The Twin-T filter circuit was used by some classic analog drum machines to create percussion sounds. Realistic tom-toms, congas, and kick drums can all be made using this method.
The Twin-T filters included in the Fragments Generator have been adapted and optimized for a specific purpose.
The idea was to create an analogue method of generating sounds at the level of individual "grains" or "fragments" similar to a traditional digital Granular synthesizer.
By approaching the process from another angle we have come up with an entirely new sub-genre of synthesis.

The sound produced by the basic Twin-T filter is quite close to the idealized grain, a decaying sine-like waveform that can easily be varied in amplitude, frequency, and position.
Typically, the Twin-T filter produces a single sound up to a few times a second. What would happen if that occurred a thousand or more times per second?
The Fragments Generator creates a constant tone that consists of overlapping and interacting fragments which can be manipulated in a number of ways.
