As you say it needs to be kept clean, and I'd suggest registration to add or make alterations to pages in it. I wish I could help to set it up, but have no idea how to go about setting up a Wiki or a webserver. My Apache webserver I've tried out once with my son, but on dialup it's a bit of a no-go anyway. The kernel I am using is from planetccrma. 2.6.10-0.4.rdt.rhfc2.ccrma (32bit). Having finished playing with vst apps a while back, I went to start qjackctl. It doesn't want to know, throwing back "the capture device "hw0" is already in use. A bit confused I run ps auxw, and this shows 5 active pid's for wine. I have, pid 4288 for /usr/bin/wine-preloader /usr/bin/wine-pthread C:\Program Files\Native. Also, pid 4291 for /usr/bin/wineserver, and the rest are using /usr/bin/wine-preloader /usr/bin/wine-pthread /home/djmons/.wine/driv. Kiliing these and running ps auxw again shows the same pid's still there, but with the comment "defunkt" . Normally you kill a pid, run ps auxw again and the pid ids gone. Qjackctl still won't start jack. I had to do a windoze style reboot to clear this stuff. Thank you by the way for "top". I havn't used this before. Right. I've rebooted, and go to wines program files. Start up Crystal through savihost with top running. Ksim at idle shows an average of 26% cpu. With top, wineserver is showing an average of 10.5%, and wine-preloader an average of 7.6%. Playing Crystal pushes the cpu up to about 50%. I mean. This ain't too bad. Wine-preloader has gone up to about 13.3% cpu and is staying there after a few minutes. Wineserver has stayed at the same cpu level. Closed Crystal and now lost wineserver and wine-preloader from the top output (which is as it should be). Cpu now running at an average of 3%. Start Triangle I . Wineserver's cpu about the same as Crystal. Wine-preloader up a bit, 8.6%. Playing Triangle I pushes the cpu to about 53% max. Closed Triangle I, and lost wine pid's from top. Tried qjackctl and starting jack, and no problems. Right. Last try, as I don't want to use synths that you don't have. Start FreeAlpha. No big difference here. cpu useage about the same as the others. FreeAlpha being polyphonic surprisingly only max'd at about 41% cpu when played. None of this seems too bad. I still can't understand why I had 5 pid's still running for wine in ps auxw. the only other bits I'd run from the wine program files were, a pdf manual, and a MS word .doc through open office for another synth manual. Now I recorded a bit on one synth and saved it as .wav. But the next question is. How do I port the output from a VSTi running under savihost and wine, to an app like Ardour? Thats a whole new ball game. Nigel.
