SplitEQ/Physion have very high latency up to 192kHz but with 352.8kHz the latency drops to half as reported by the Ardours DAW:

40.66ms  352.8kHz SplitEQ
29.80ms  352.8kHz Physion

I still have to measure precisely but I realize that in a live context the difference can be heard.
I would like to know if this is an expected thing or is it a problem of some kind, Thanks.
