I'm trying to write a software synthesizer that recreates the sounds made by classic synthesizers like the Moog and the DX7. Does anyone know of any code resources for something like this? Thanks.
There are an awful lot of C/C++ libraries out there, most no longer updated. There's not much for C#, but I have seen a couple. I haven't really used any of them in anger, so I can't give any recommendations.
I would start with Harmony Central and see if you find anything of use there.
Alternatively, a search for analog synthesis on sourceforge.net has plenty of results.
