rotating a knob (midi) while playing produces a xrun

[GoogleCodeExporter]

I affect a midi know to the cutoff frequency of the lfo.
I play a sound on the keyboard and then, I rotate the affected knob.
The sound produced is "poor" because of the lot of xruns generated.

I use the latest amsynth trunk.

Is amsynth using a lot of CPU when this happens?

It's a strange problem - it hasn't been reported before, and I can't reproduce 
it.

Does it also happen with older versions of amysnth? (like the 1.2.3 release)

Closing because no further information was received.

Would need to know which audio back-end was being used (oss / alsa / alsa-mmap 
/ jack)

Sorry for the delay.
I will try to reproduce the problem with the current version of amsynth.
I used the jack back end.
If I am able to reproduce the problem, I will reopen the bug report with more 
details. Otherwise, I will leave it closed.

Best regards,

YC

Tested on the current trunk with the jack backend and with a realtime kernel. 
No problems notices anymore.

Best regards,
