A few months ago, I created a series of recordings in response to an incredible article highlighting some of the most remarkable properties of the Buchla Oscillators of the 100 and 200 series. The article is Dan Slater’s Chaotic Sound Synthesis, published in Computer Music Journal, Summer 1998 Volume 22, Number 2, ISSN 0148-9267. Here is a photograph from the article, of a CBS Performance System 3 featuring a chaotic patch:
This article was also available for a period on the web, at a time when there was very little info of Buchla systems to be found. If only those who now decry what they perceive as “secrecy” on the part of Buchla users knew how hard it was to find out exactly what a Kinesthetic Input Port was ten or more years ago! In any case, I digress.
The article is a wonderful resource filled with several very interesting approaches to creating chaotic sound – and once my 200 was operational, I almost immediately began directed experiments in order to explore some of the territory Slater describes.
Chaotic Synthesis Recording #3 (edit), August 2009:
If you would like a copy of the entire (19:40) recording, I have self-produced a limited CD release of 20, priced at $10 to be sold at some upcoming shows. E-Mail me if you’d like to order one. Here is a photo of the CD and the single sided bristol “cover” – that features an illustration of the patch used for the piece:
