FWIW, the latency reported by jack on my kit is 5.33ms. I've heard that <10ms is not noticable by the human ear, and my experience pretty much agrees with that. > Actually, there is one other thing, if you are using USB sound cards > for MIDI in and audio out, make sure they're not on the same USB bus. > That caused unpleasant latency as well. > > Dave > > > More below... > > > > > On 23 Jun 2011 11:13, "Krzysztof Foltman" <[email protected]> wrote: > > > > > > On 23/06/11 08:17, Thomas Orgis wrote: > > > > > > > So, my Roland drum brain is a bit quicker as the current c... > > > Not as unlikely as you think.
