Hi, QjackCtl 0.2.17 update release is out. Directly from the change log: - Systemic I/O Latency settings are now featured for the alsa, oss and coreaudio backends, letting you specify the known latency of external hardware for client aware compensation purposes (thanks to Wolfgang Woehl, for the reminder). - Update on last backstage changes to the coreaudio backend options (due to Stéphane Letz. Thanks). As always, you can grab the source tarball from the usual place: http://qjackctl.sourceforge.net/ http://sourceforge.net/projects/qjackctl Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
