Hi, pdrs FYI Just tested Pd version 0.40-2, jackdmp 0.7 and Qjackctl. Seems there now is a stable free ASIO audio server on XP. I used Pd to monitor demoversions of Reaktor, bAbelton Live, NordModular G2 and Reason with little or no flaws. You can get jackdmp here<http://www.grame.fr/~letz/jackdmp.html> mvh/Steffen Leve Poulsen
