IIRC someone on jack-devel mailing list had issues when using mplayer with the value 64 and it was solved when using the value 1024. But as I mentioned before, for my USB MIDI there was a difference between system timer and hr timer, but there was no difference for the value 64 and 1024, when using hr timer. Btw. I don't understand what a maximum frequency in the context does mean. If 64 or 1024 should have impact, what would be the result? System timer for a kernel-rt is set up to 1000Hz and hr timer is at 1000000000Hz. What is 'max-user-freq' for? Cheers!
