Absoulutely not. Organ pipes take some time before they will sound,
this can easily be 20 ms and considerably more for some. Apart from
that pipes are not all at the same distance from the player, this
again can easily introduce variations of 20 ms or more, even between
pipes of the same rank.

Aeolus doesn't care or even know where the MIDI is coming from.
And it does quantise note on/off to Jack periods. Nobody ever
complained about that.
