[PD] Latency question (non-audio/midi/osc)

[Sam Ross]

Hello list,

Is it (still) the case that Pd's midi buffer is connected/synced with 
the audio buffer? (Sorry if any terminology incorrect).

If this is the case, is it correct that the best way to get lowest 
latency control signals is to run control data in a separate instance 
that is removed from any audio processing, with the audio settings set 
for as low a latency as possible? So, delay 0 ms, I presume? And would 
altering the sample rate and block size also have an effect?

Thanks for any help you can give in assisting my understanding.
Sam.
