Sound designer Alessio Mellina has released r0b0.coder, a free effect processor for Windows and Mac.
It features a series of different real-time processing techniques that can be applied to a live input or .wav samples.
Parameters can also be randomized and/or controlled by LFOs in order to achieve unexpected timbres.
The r0b0.coder is a free standalone application for Windows and Mac (does not require Max/MSP installation).
