&gt; I my case I want to have only a drum synth playing<br>&gt; and controlling it with midi messages.<br>&gt; I think that doing it with Jack would give me extra delay.<br><br>Well, Hydrogen doesn&#39;t seem to have Jack MIDI, so you couldn&#39;t control it that way anyway. This is proof of the network effect -- the more existing apps use Jack MIDI, the more attractive it becomes to new apps.<br>
<br>But in general, I don&#39;t see why two apps communicating over Jack MIDI would encounter more delay compared to two apps communicating over ALSA MIDI.<br><br>-- Dan<br><br>-- <br>Dan Muresan<br><a href="http://alumnus.caltech.edu/~muresan/">http://alumnus.caltech.edu/~muresan/</a><br>
