I have jack 1.9.7

if I increase to 48000 qjackctl gives 42.7 ms. (21.3 when using 512/period)

how would i see the improvement with /usr/bin/jackd -S ?
it doesn't change the expected latency in qjackctl when I do that.

One of the annoying things is the delay between the midi keyboard
and the actual sound. I guess it has to do with the one we are tuning 
now, right?
