Andrew Burgess' Pluggo Madness

Andrew Burgess has released a sweet collection of pluggo based plugins.

Fire - super multitap delay [ VST | AU ]

It's a sort of multitap delay with panning and controllable morphing between settings.
Instead of controlling each echo separately, there's a bunch of parametrized functions that you can use to generate various kinds of effects.

LiveCut - a real time phrase based beat-slicer [ VST | AU ]

It is a live beat-slicer but instead of manipulating equal chunks of audio like most beatslicer do, it works on the notion of audio cuts whose length and number of repetition depends on the context and the cutting procedure. cuts are organized in blocks which then form a phrase. see Image below. And each phrase can be ended by a roll or fill.

Maestro Frankenstein - "An Application for the Creation of Geophonic Music"

That fact someone had the need to create a beast of a program that transforms your tabular data into music, gives me a warm fuzzy feeling inside. I mean, who wouldn't want to transform the tremors of Mt. St. Helens into a symphony? Really, who???

From the author:

Have you ever wondered what climate cycles of the last million years SOUND like? What would happen if you turned tide level data into sound waves? If geological cycles could make music - what would the melody be? The harmony?

Maestro Frankenstein is a unique application that is designed as a multitrack data sequencer to map timeseries data to notes or musical control values. Although designed with geologic data in mind, Maestro Frankenstein creates a score from any timeseries data and plays it back in realtime with any instrument (MIDI, VST or built-in synth) that you specify.

Vox Machina - text to audio converter

Vox Machina is simple, but usefull. All it does is render text into OSX's synthesized speach. That's it. But now you two can create wonderfull synth vox just like Outkast and Radiohead have done.
