I agree the main goal of Csound is to provide a flexible and always
growing set of tools for sound design, but I´d like to see implemented
some really idiosynchratic presets from some old synths as new opcodes.
Cook´s ones are a valuable addition, but I´m sure the DX7 has a dozen or
so of established presets, the same with other synths. Hundreds of
presets could be implemented this way. Of course you could do whatever
you wanted with them ... but a DX7 bass is a DX7 bass, a piano is a
piano, and so on. It is convenient to have them ready to be called.
Btw I hate presets ;-) but you can learn a lot from them...
