<p dir="ltr">This has to do likely with your audio latency settings. Try the pd-l2ork shortcut in the unity menu. For best results run jack first then run the said shortcut. The shortcut provides aggressive 5ms audio latency which runs perfectly fine on our L2Ork atom netbooks with lowlatency kernel. If the lag is on midi side, that needs to be investigated further.</p>

<p dir="ltr">With 1.9.8 and pd-l2ork all your problems will be solved except for the one caused by jack which in your case should not be a problem unless you physically disconnect (accidentally our otherwise) your audio hardware while jack is running.</p>
