Check on eBay for a Synclavier, made by New England Digital. By now, it's 25-year-old technology. But for years it was the only synthesizer which could take attack of one sampled sound and combined it with the wave-form of another sampled sound. Pat Metheny and Oscar Peterson were big proponents. Check out http://www.digidesign.com/ for high-end audio recording studio software/hardware. Twelve years ago, the software was described in a magazine article, with a 3-D graph of of FFT analysis. I'm sure that technology is still one of the cornerstones of its system. A local recording studio just moved its PC-based system out in place of DigiDesign's Mac-based systems, an investment well into the five figures. The digital editing is quite powerful, allowing correction for poor intonation, poor time, in short poor musicianship. Did you ever buy a new set of headphones? Bill Ballard RPT NH Chapter, P.T.G.
