Yeah, the cost of starting an additive synthesis note can be fairly expensive as with a worst case instrument and default settings you'd need to do 256 1024-point IFFTs per part and a bunch of math leading upto the transform (in addition to all sorts of other initialization stuff (like the memory allocation which I just finally removed)). I've got this cost almost removed in my local version, but it's not release ready. --Mark
