Hi, Yes, I do understand Brian's approach - chatted a while with him many moons ago! Yes, he used the various generative tools to create chunks of sound to be used in building pieces. You are absolutely right about these processes going nowhere - which is why I generated the midi tracks, popped on the VSTi, and then generated the waveforms. From then I automated the volumes and pans to create some "musical interest". As you say, the software tools pretty much lack the ability to create "standard" musical structures as we typically know them, and being free running, they of course continue "doodling" for ever (not a good thing), although Brian did do a 3 hour piano concert where he sat and pressed the keys with his arms folded - not even a "prepared" piano either - the idea was to listen to the "structures" within the sound of many notes. Most walked out, but a few die hards stayed to the end. Go figure! I simply see this technology/technique as a means to create interesting textures which you just might not have happened upon yourself, but with a certain amount of control to generate in a key or set of keys with a certain harmonic structure, to allow the snippets to be used in more "mainstream" compositions. Hope this makes some sense as to where I was coming from. Cheers, and thanks for the comment, all good, dB
