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?

Hello Dave,
Thanks! That's already a bit of an older onboard soundcard, I am not
sure how it performs when using JACK. I've come accross these AD
devices at work and if I recall correctly it doesn't do a great job.
You could try raising the sample rate to 48000. And are you using
Jack1 or Jack2? You can find that out with the terminal command jackd
--version If you're using Jack2 (so jackd version 1.9.x) you might
want to try adding the -S option to the Server Path line so that it
reads /usr/bin/jackd -S
Best,
Jeremy
