Changing patches doesn't cause it to disconnect from jack anymore. I often hear a slight crackle but that doesn't register as xrun. I pushed it hard using for example Folderol's HyperMatrix patch which is very demanding. With this, as well as some other patches, it crackles sometimes, without xruns. When you really push it over the limit it crackles heavily and produces xruns, but that's to be expected when there's no more cpu left to burn. Here's where I just saw that an rt kernel makes quite a difference: with stock 2.6.30 kernel I can play far less voices and once it gets near 100% cpu zynaddsubfx's jack backend is gone, forcing me to restart the application. So yeah, very good, the show stopping bugs seem to be mostly gone, it's usable again, which is actually just great :) Philipp _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
