The Yamaha (the one at Yale's CSMT, Adam Silverman should be able to tell us which one) did have FM capabilities. However, I didn't think of that as "synthesis from scratch." Looking back at Gary's query, however, I see that he would indeed qualify it. >The sample playback side of the Yamaha does include a bunch of >synthetic waveforms, but Gary was more interested in the FM synthesis >side, which uses oscillators (sine wave and variants) as raw material >for cooking up much more complex sounds. Yamaha's synthetic waveforms are themselves FM-based, and can be used to FM one another.
