Now adding bandwidth on each partial kind of adds a chorus detune effect in a way. How does this compare to other single instruments not in a group. It seems like it would be very good to model wind instruments because of the breath noise but what about instruments like piano and guitar or something. Can these techniques be used to create more realistic models of other solo instruments. I have always enjoyed the sound of ZynAddSubFx. I want to know what kind of filters you are using becuase I like to do most my stuff in csounds. What would be cool is to have a csound export function to do that in ZynAddSubfx. Are the filters similar to the csound butterworth filters like butterbp? If not what csound opcodes/filters are similar to what ZynAddSubFx. I want to use ZynAddSubFx to create sounds but I want to have these sounds in csound without sampling it. Thanks, Jeremiah
