I can see that there is value in the ease of use that the preset opcodes you
describe would afford. I know you can do FM synthesis in Csound (I alluded to this
previously), and you can even do 4-op FM with a single opcode if I am not mistaken.
There are also many other "building-block" type opcodes in Csound as well as
special-purpose opcodes as you point out, and there is room for more. Too bad I
can't help code them, since I have zero programming ability. I still think an
orc/sco that emulates the original preset is the most educational and flexible
option, but those aren't the only considerations by any means. Anyway, your idea is
very interesting to me and I hope it didn't appear from my last message that I was
trying to throw cold water on it.
