The sound clip presents a generative fine grained microtonal ambient music process. The system as it is presented here doesn’t need any live human input. I have given certain parameters and limits in which the process functions and acts as a composition tool.

In the ready live setup I’ll introduce a couple of hardware synths that are controlled by the microtonal midi messages derived from the original source material. In this demo I have set the base time to 5 seconds, which I have then multiplied in eight different ways to create a rhytmic pattern of independent cycles.
The timers trigger an FFT patch to pick eight strongest frequencies at the given time. The original vocal sample loops out of sync of the process, so the picked frequencies never quite repeat themselves.
The original sample can be heard in the background. It is resynthesized by eight independent sine wave oscillators, four channel karplus-strong string modelling patch and two channel granular synthesis derived from the original sample.
The second demo uses the same parameters, but the original sound is a recording of rail yard at night. The granular process uses a whistle of a train as the basic waveform.

The process can take any live or recorded input and decorate it with an ambient soundscape. During a live set I will concentrate on the sound processing, and I will also introduce a microtonal keyboard which allows me to play along with any source material. The tuning system is completely fluid and is based on the frequencies than any musical system.
