the_defiant Posted January 18, 2007 Share Posted January 18, 2007 I've tested Reason 3.0.5 and Traktor 3.2.0.0.85 on osx86 10.4.8 (with all of the available kernels: mifki / semthex b8 / semthex b9 /semthex sf3 /semthex sf9). After I launch Traktor( or Reason) and leave it like that, Activity Monitor says that it eats up 20% while the app is sitting IDLE. Reason is 100% usable, though, the same thing can be said about Traktor. Still, Traktor seems to have a bit of lag if I load a track in a deck while another one is playing in one of the other decks. I know all about setting up the cache / various beatmatching options (I'm using phase voc.) I've tried using osx86 without HT and it was the same thing, no improvement. I'm using the AppleHDA.kext with alcinject and I've got 2x "line outs" / 1 line in / 1 mic in / digital out working. I thought these problems were somehow related to the small buffer that the kext specified, 30 samples. I've modified it up to 256 and 512 and it keeps doing the same thing, it doesn't seem to make any real difference. I've tried various sampling options, 44100/96000/192Khz, the same thing happens. I tested it an hour ago, inside vmware and it does the same thing (I should rather say worse), with the latest DVD from JaS + PPFv1. The configuration of the PC is as follows: P4 531 HT / 1GB DDR2 RAM / P5LD2-VM BIOS 1102 REVISION 2.0 ALC882 / GMA950. The same apps work very well under Windows XP, but I'd It's weird, because iTunes doesn't use the same amount of cpu, it uses 4-5% at most, when used with full quality processing and ~1% when idle.

VooD Posted January 20, 2007 Share Posted January 20, 2007 Have you checked if real macs have the same behaviour? Link to comment Share on other sites More sharing options...
the_defiant Posted January 20, 2007 Author Share Posted January 20, 2007 I will, as soon as I get the chance to test these apps on a real Mac. As for the trouble I'm having, I've tested Ableton Live 6.0.3. It seems Ableton Live eats less CPU while IDLE on osx86, 6-7%, but, that increases if I reduce the size of the buffer. Although I did a test and increased it, it didn't go lower than original 6%. Traktor does the same thing, it uses less CPU in idle if I set a large latency (50ms), about ~10% instead of the original 20%. I will try to test it with an M-Audio Firewire and see if it keeps doing the same thing. If it does, then I'll go and test on a real Mac. Link to comment Share on other sites More sharing options...
nagal Posted January 21, 2007 Share Posted January 21, 2007 The thing with audio apps, even when you are not doing anything with them, they are still doing stuff. So when idle it is expected to see CPU usage. How much depends on the app, the computer and what (if anything) is loaded into the app (VI,AU,VST etc).

the_defiant Posted January 21, 2007 Author Share Posted January 21, 2007 Well, it uses 0-1% cpu on Windows XP ( LIVE/REASON) and I didn't add any VST plugins or anything else on osx86. On the Windows side, I do have VST plugins in Live. We'll see if 10.4.9 changes anything. Link to comment Share on other sites More sharing options...
