my
first guess is 'no', because phasor~ is attempting to stay synced to the Global Transport and this falls outside the realm of the signal-vector of your pfft~, so the two will often be slightly out-of-sync unless you find a way to hard-sync the phasor~ with the bin-index of fftin~(i don't understand why: but i do get less ringing when i set my signal-vector within 'Audio Options' of Max to 64 or 128... maybe having the outer signal-vector size fall within the range of half your FFT-size helps somehow? ...but i can still hear it's a bit imprecise).
but i feel like there maybe some tricks people could come up with using sah~ to sample-and-hold the incoming phasor~, or possibly reset the phasor~ using a signal at certain times synced with that bin-index outlet... (i just don't have time to come up with all these guesses for you, and i also don't know what the larger patch does nor the longer-term goal here, so it's probably better i give you this guess and you will end up learning more by searching stuff out on your own related to this...)
since you're working with direct real/imaginary values(what you've created is more efficient than the equivalent using cartopol~ to translate real/imaginary into amplitude/phase ...and working with 'phase' is where you could use the phasewrap~ object to wrap within -π and π as mentioned in your other thread, but i'm not sure this is actually what you're trying to do, anyways -> it's more useful when you're trying to detect/rework specific parts of the frequency spectrum separate from magnitude/amplitude, but in your patch, it seems you're only reworking the overall magnitude by multiplying both real/imaginary by the (inversed)output of phasor~), i recommend going over these more too, particularly the first one:

https://cycling74.com/tutorials/the-phase-vocoder-part-ii my best guess: it IS possible, but it's actually both the fft-size and hop-size(defaults to 2) which will make this difficult to sync ideally to a phasor~ which is already synced to the global transport(instead of to something within the pfft~... the signal-vector size within a pfft~ is dependent on your FFT-size, outside the pfft~ it can be different). you just need to study more closely how these parameters interweave within the overall system in order to work it around what you're trying to achieve.
