I've been in the music business since the 1970s, demoed synths (I co-hosted the UK Launch of the Roland D-50, for example), programmed loads of sounds, done a bit of reviewing and some columns for Sound On Sound magazine in the past, and done some ghost-writing too. I program things in a diverse range of languages (Quartz Composer, Python, Max, HTML...) and write M4L when I get time (I've been very distracted for the last few years for a number of reasons...). Oh, and I wrote the undergraduate textbook: Sound Synthesis & Sampling.
