Hey guys!<br>
<br>
I was the one who tested this for Mike. I used Qtractor and Rakarrack.<br>
In Qtractor I had Audio track 1 and Audio track 2.<br>
Signal from track 1 was routed into Rakarrack and then into track 2.<br>
<br>
The latency is there and quite audible.<br>

Maybe it has nothing to do with this:<br>

I also wonder why JACK's zero-copy implementation could cause issues<br>
for<br>
audio apps. There was an issue for Qtractor, anyway, until today I<br>
believed that there is no latency when using JACK in any way, excluded<br>
connections regarding to the sound card.<br>
I never noticed a latency, but maybe it's because I used this insert<br>
connections for time related FX only, e.g. flanger and delay.<br>
<br>
Interesting to read about latency I never was able to hear.<br>
<br>

But anyway, what version of Qtractor do you use? There was an issue related to a supposed zero-copy implementation for outdated versions of Qtractor, that a long time ago was fixed in SVN or even in the previously used CVS.<br>
