I took a little look a while ago, and it appears that there are

But I'll think that effective use of fftw-wisdom would end up
out-speeding GPU anyhow, because it's all precomputation...

I'm not sure how fft even factors into the realtime/processing thread. Will have a look and get back to you, but I'm pretty sure most of it is buffered.

The effects, I would have to look at each.
