Hi Mark. A Wiki is the best option for keeping this info. 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.
