The thing to be avoided is code that e.g. generates a

every fourth period and does almost nothing in the three periods in
between. Or a synth that generates a peak load whenever a voice is
started and much less while the note lasts. IIRC yoshi/zyn use FFTs
in some of the algorithms, so this sort of thing could happen.
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.
