In the documentation, it does not say what message (if there is one) to send either object to change its FFT windowsize. Similarly, in pfft~, there does not seem to be a message to be able to change windowsize. Is this possible for an FFT? I’d like to have an FFT windowsize that matches the size of a grain, for pitch analysis of a single grain.

Check the pitch~ help patch.
No message – use the arguments in object.

Args are – def.
Buffer size = 1024
Hop size = 512
FFT size = 1024
Window type = Blackman 70
Initial delay = 0
# of pitches = 1
# of peaks to find = 20
# peaks to output = 0

Hope that helps.

You might have to use multiple instances and route to the one you need.

But if you just send the sound of a grain to fiddle~, what is the result? It might just be good enough…

What about Sigmund~ ? will do what you want. http://crca.ucsd.edu/~tapel/software.html
