I know you are a fan of Radio 3's "Mixing It" programme, but wondered if you heard last night's programme. They did a feature on a piece of software called "Super Collider" which is downloadable from the net : http://www.audiosynth.com/ They interviewed someone working with this who was/is guitarist with the Pogues (! -can't remember his name). So he explained how he had used the programme "live" - which is really for generative synthesis - like koan - it creates something different every time it runs, from basic elements. So he has set it up with software equivalents of things like delays/loops - but more complex parameters - and then played simple things on acoustic guitar, which were transformed by the programme into strange sounds - he explained it as "granular" synthesis. So the programme would take small parts of the sound and loop or play these parts backwards at different but related speeds - depending on the "rules" you programmed in. It made some really strange sounds and created something new that still sounded natural and acoustic - so it was taking the sound of the acoustic guitar, rather than some synthetic basis, for the overall tone. Anyway - I was thinking it would be amazing for solos bass gigs and wondered if you had checked this out or heard of it yet? There's probably a better description on Radio 3's website!
