I wonder, if someone here knows about why this happens this way: I have two meters that monitor my CPU load. One of them shoots through the roof rather quickly while the other one is bored. Usually I wouldn't mind, but I'm getting ASIO overload errors with one processor hardly doing anything. Is this a known issue and if so, can I somehow work around it? I working on a DUAL G4 533Mhz, 900MB RAM, Logic Platinum 5.5.0 Maybe in acouple of weeks when I'm getting 6 this will all be over with... Thanks for the help Hans

Hans, we've just had a big thread on this. Search the archive for the thread "Dual Processors; Anyone Experiencing This?" It's not a bug and so far 6.0 looks like it won't change anything. -- ==/==/==/==/==/==/==/==/= Paul Najar Jaminajar Music Production http://www.jaminajar.com.au

>It's not a bug and so far 6.0 looks like it won't change anything. I asked at NAMM if it was addressed. The answer was no, it's just how Logic is set up to use one processor for MIDI, the other for audio. I don't have a DP, so I don't know much about this area. Would be nice if they someday made an option to optimize logic for yours particular use (a mode to split the processors evenly, or split like it is now). Colin Miller

My guess is give it about 12 months. For all us OS 9.xx DP users we'll get a pretty decent speed bump when we finally go to X.

For all us OS >9.xx DP users we'll get a pretty decent speed bump when we finally go to X. > Hi Coling, thanks for the advice, but I have to say that this option then takes away the possibility of using busses as subgroups as the audio is then sent out put 1-2 directly. Plus on every mono track I have to use a stereo track instead to not have that track show up on channel 1 OR 2. So this option is unfortunately not for me. If Emagic people are reading this (I know Michael Haydn is with Emagic) this should really be addressed and I believe that Logic 4 used the Dual Processors in a better way! Thanks to all for the advice Cheers Hans

Does anyone have a suggestion for something to use on direct guitar tracks until Amplitube gets ported to OSX? It doesn't have to do everything, but some overdrive/distortion is needed. The stock Logic plugs don't really do it for me. Or should I just go back to tracking with the tone I want? I'd gotten out of that habit after using Amplitube for awhile, and now I've got old tracks I'm transferring in from DP/PT that have dead clean guitar. I suppose I could bounce them in DP and then bring them into Logic too...

I have to say first that I have not tried this trick yet but I think you are missing something that was in the original instructions. You set the output of the I/O plugin to something valid then you *bypass* the I/O plugin. This way there is nothing actually getting sent to the I/O plugin from the channel so you don't have worry about using that output for something else.

Ok, then that was my bad and reading sometimes actually helps. Sorry ! I will try again! Cheers Hans

THe Emagic reps using Logic 6 under OS X said that there isn't any change in how the dual processing is handled (midi on one, audio on the other). Do you know something they don't what you know its coming? Or maybe you are just speaking in general and not specifically about the processor balancing? Colin Miller

THe Emagic reps using Logic 6 under OS X said that there > isn't any change in how the dual processing is handled (midi on one, audio > on the other). That's correct. That's why I said "eventually". See, even if Emagic wanted to do something about all this under OS 9.xx they could not because OS9 does not have symmetrical multiprocessing. OS X does. What this means is that under 9 you can't let the OS decide what tasks it's going to send to which CPU or to have one big task handled by both processors simultaneously. Under X you can. But based on what beta testers have said about LAMP 6 it implies that the application in question has to do it's part as well for better CPU distribution. That's why I also said I'd give it about 12 months for this to become reality - that is - for Emagic to sort it out. The other thing symmetrical multiprocessing gives us is the ability to give both CPU's (or even 4 or 6 CPU's) one big task to be crunched by all of them at the same time. No other Mac OS (or hardly any other OS period) can do this. This is one of the things that makes OS X so advanced. > Do you know something they don't what you know its coming? No. Only what I said above. I'm simply putting two and two together... > Or maybe you are just speaking in general and not specifically about the > processor balancing? To an extent I am speaking generally. But Emagic have had a long history of "eventually" taking advantage of most if not all the features a particular OS has to offer. Examples of this would be QuickTime instrument and movie support and Direct X plugin support. Now given that Apple now owns Emagic, and LAMP now only supports one OS (9&X) I would GUESS that support for better CPU distribution can't be too far off. -- ==/==/==/==/==/==/==/==/= Paul Najar Jaminajar Music Production http://www.jaminajar.com.au

OK, just checking because Logic 6 on OS X running at NAMM still worked the same way as in OS9 where the audio side was much higher load than the MIDI side. It was very evident in the Freeze demonstration where they tried to show how the CPU usage changed when a track was frozen. Colin Miller
