I got the same errors using the 2.6.32 (or maybe it was .33) kernel, does that matter?<br><br><div class="gmail_quote">On Mon, Jan 31, 2011 at 4:38 PM, linuxdsp <span dir="ltr">&lt;<a href="mailto:mike@linuxdsp.co.uk">mike@linuxdsp.co.uk</a>&gt;</span> wrote:<br>

Hello guys!<br>
<br>
I&#39;m trying out the pianoteq-trail, which is awesome! But I get pretty bad performance, and when I start the app I get this error-msg:<br>
<br>
Midi thread could not acquire real-time scheduling, error 1 -- Operation not permitted<br>
Midi thread could not acquire real-time scheduling, error 1 -- Operation not permitted<br>
Midi thread could not acquire real-time scheduling, error 1 -- Operation not permitted<br>
Jack error: Cannot use real-time scheduling (RR/5)(1: Operation not permitted)<br>
Jack error: AcquireRealTime error<br>
Multi-core: could not acquire real-time scheduling, error 1 -- Operation not permitted<br>
<br>
Do you guys have any idea what the problem might be? Googling it has given me nothing so far! I have both my username and the groupname &quot;audio&quot; setup properly in limits.conf (rtprio, nice and so on) via a tutorial I found a while back. I&#39;m using ubuntu studio 10.04 but with the latest 2.6.38-1-generic kernel.<br>

<br>
Best regards!<br>

Perhaps it has something to do with this:<br>
