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 herehttp://www.grame.fr/~letz/jackdmp.html
