Buzz
Buzz is the first ever "easy to use" free modular software based synthesizer. What this means is that the entire system is based on objects, which may be routed in a modular fashion, giving you the freedom to be as creative as you want. For example, if you wish to run 3 Physical Modelling synths and a Drum Machine through 2 seperate Stereo Delays, into a Mixer, through a Compressor and Parameteric EQ, and finally out to your speakers - no problem. Lay down your synths, connect the wires and you're done. Every aspect of Buzz is built to be controlled in real-time.
