Hi, I realized that this would be pertinent info this morning, thanks for reminding me...<div><br></div><div>I&#39;m on Arch Linux, and I used both kernels 2.6.33-rt and the standard 2.6.32-LTS (long-term support) with the same results....</div>
<div><br></div><div>It&#39;s Jack 0.118.0-2 and also 0.120.2-1 that were problematic for me. They also caused weird behavior with fluidsynth-1.1.3--with my M-Audio KeyRig 49 USB keyboard, there were HUGE (.5 seconds!!!) midi delays.</div>
<div><br></div><div>I installed jack2-svn today and the fluidsynth issue is now gone. And, although the PianoTeq xruns are much better, they are still slightly more apparent than with Alsa alone.<br><div><br></div><div>I don&#39;t know what happened, but, being pragmatic, one has to just find versions that work....yikes!</div>

Hi all--<br>
<br>
I&#39;m wondering if anyone else has experienced this:<br>
<br>
I&#39;m considering purchasing PianoTeq, but I wanted to try the demo. It<br>
seems to work better with just the alsa driver than it does with jack, a<br>
reversal of the usual situation.<br>
<br>
I tested this several times by playing fast glissandi on the default<br>
piano preset. Each time, my little EEE-PC netbook under jack choked with<br>
xruns and a brief silence while PianoTeq &#39;reset&#39; itself, but Alsa alone<br>
chugged away with no xruns unless there was an extreme amount of load....<br>
<br>
I&#39;m wondering if anyone can comment on this. It seems odd, especially<br>
since the jack developers claim jack adds no latency by itself to the<br>
picture in any situation---so, do we have a situation where the code is<br>
better written for the alsa driver than for jackd? It seems we do, in<br>
this case....<br>
