Gothca. OK. If I hold a note down (after hooking a keyboard to that, running xsynth) and sit here, I'm getting crackles every 2-3 seconds. It's not regular enough to time, and doesn't seem to be associated with anything in particular. Moving the mouse in of itself doesn't seem to cause anything. Moving over the kicker and making the icons zoom up, the dots ticking on the clock, the CPU status graph (ksysguard applet I guess)--none of these seem to have a direct 1:1 effect. But if I have two windows on the same screen, and I change the focus from one to the other, that's a pop. If I change which desktop is visible, that's a big pop. If I grab something and drag it around, it sounds like popcorn. > > Do you mean frames/period or periods/buffer? If the latter, which I > > assume, then I can't change it. > > No, I meant the former. Just to see, like. Oh. OK. I'm dialed up for the lowest possible latency normally, which is 512|48K|2 (Hardware won't go any lower.) Switching to 4096|48K|2 sure enough, the problem almost went away! I still got an odd rare pop. 2048|48K|2 is very nearly as bad as the original settings. OK, I had a play and tried running through these again, and it's repeatable. At the 171 msec settings (4096|48K|2) it does still pop once in an odd while, but it's pretty random and irregular. Happens more often when playing rapidly. If I hold a note forever, it seems to go forever without pops. The focus-changing pop effect is completely gone, and I can drag windows around without affecting the sound in any way. But at this setting the timing playing with the keyboard is way off, due to the problem you were talking about earlier with this example client not being very well-written. Worse, I'm back where I was before I started trying to tweak up JACK. If you remember, I had settled in on these 171 msec settings as my stable "magic numbers" but I was having a lot of problems out of soft synths playing with really bad timing until I reduced the JACK latency. Something about using JACK for the timer and the minimum period size. I don't quite remember the details, but I had a reason for fiddling with JACK, and tweaking it down to 21-odd msec took care of the soft synth timing problem. Well, there you have it, FWIW. -- Michael McIntyre ---- Silvan <[EMAIL PROTECTED]> Linux fanatic, and certified Geek; registered Linux user #243621 http://www.geocities.com/Paris/Rue/5407/ http://rosegarden.sourceforge.net/tutorial/ ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________ Rosegarden-devel mailing list [EMAIL PROTECTED] - use the link below to unsubscribe https://lists.sourceforge.net/lists/listinfo/rosegarden-devel
