nvram -p will print the firmware variables so that you can check to see that SMT is set to zero.Vance wrote:- Thanks for the update steko
- I just the test on my Macbook Pro. It's a dual-core Mid-2009 machine, with hyperthreading. Basically, I could predict from my original results that I would be able to run 4 tracks seamlessly, with massive issues on the 5th track.
- I tried disabling hyperthreading by using the "sudo nvram SMT=0" command in Terminal. After rebooting, it made no difference to the test - 4 tracks was fine, 5 tracks was horrible. But I believe that's because the command actually didn't disable hyperthreading properly. As a dual-core CPU, with HT disabled, OS X should only be able to see the 2 physical cores. The OS X CPU meter showed the usual 4 cores, and during the test, OS X showed activity on all 4 of those cores.
- So it seems that that command isn't properly disabling hyperthreading, at least on my MBP. I'm reluctant to go too deep on testing that solution on my Mac Pro because I have to stay productive & can't afford downtime on that machine. I'll do my tinkering on the MBP (now that I've established that my test scales appropriately) and once I see something change/improve on the MBP I'll give it a go on the Mac Pro.

Re: Multicore support needs a big overhaul
Re: Multicore support needs a big overhaul
I just wanted to pipe up in this thread...
I've recently started using Live again and, coming from Reaper, I had a big surprise in store. I started transferring/translating/converting/porting my Reaper projects to Live last night, using the same plugins, routings, settings, and content, and on the same machine, and to my horror, I was getting dropouts and all sorts of nasty noises (in addition to the ones I wanted). It was quite a hard pill to swallow, to be honest, and it was an awful shock.
Admittedly, I use Maschine and when NI implement even some multicore support, things will undoubtedly be better, but I still hope Ableton can vastly improve the way Live handles multiple cores. It just takes all the fun out of it when you have to strip back a set, even though the actual CPU usage of the machine is never higher than 23%.

Re: Multicore support needs a big overhaul
I was trying out Reaper on a 3.4 Ghz I7 and saw differences of similar magnitude.
Quite depressing really...

Re: Multicore support needs a big overhaul
Keep in mind though, that a lot of resorces goes to keep everything prepared to be played and remixed, moved, drag n droped, without glitching the signal. The live set comes first. Naturally this requires more resources then your typical linear "of line" DAW.Mister36 wrote:I've recently started using Live again and, coming from Reaper, I had a big surprise in store.

Re: Multicore support needs a big overhaul
While there is truth to this and Live undoubtedly does more behind the scenes in some areas than a typical linear DAW, when it can't stand up against a linear DAW to do stuff that another (Reaper) can do, it tastes a bit sour still, especially when these are things you can't actually see taking up the resources (unlike if you have three million plugins loaded, for example). Additionally, though, I had no audio clips loaded at all, so Live wasn't having to be ready for their launch etc.ze2be wrote:Keep in mind though, that a lot of resorces goes to keep everything prepared to be played and remixed, moved, drag n droped, without glitching the signal.

And I realise I haven't given that much info and a very comprehensive account of my experience but I just wanted to remark upon my shock, horror, and disappointment.
Re: Multicore support needs a big overhaul
This is demonstrably not the case at all - look at the CPU meter readouts in my original post. At the point when Live starts to become unusable due to dropouts, CPU usage is very very low indeed... Reaper manages to make use of a lot more CPU power before it starts to glitch, in comparison to Live.ze2be wrote:Keep in mind though, that a lot of resorces goes to keep everything prepared to be played and remixed, moved, drag n droped, without glitching the signal.

Re: Multicore support needs a big overhaul
yeah, i was all nostalgic for fruity so i downloaded it again. then i remembered why i stopped using it. no real audio recording or editing.nebulae wrote:^ I'm really looking forward to getting back to my FL Studio license once they release FL for Mac.
i remember loving that piano roll but this time i was annoyed with being forced to use tools instead of just clicking to add and double clicking to delete notes.
it does look cool, but then the windows tend to overpopulate the screen when you really get into making a song.
btw i remember a few "mac fags" this and "mac fags" that from you.. so are you a full on fag now or just bi-computing?

Re: Multicore support needs a big overhaul
But now FL do better audio editing than Live. Sry, I made a digression.
Re: Multicore support needs a big overhaul
not for me it doesn't.
you have to use that edison thing that just adds another window.. and isn't edison destructive?

Re: Multicore support needs a big overhaul
i can't stand the way FL handles audio. Edison was a pain when i tried to use it. it would take something pretty damn special for me to try it again. i am a fan of FL for MIDI sure, but for me Live is where it's at for that in terms of elasticity. i do use Sound Forge as an editor if i feel the need to go deeper into those kind of edits but zooming, splicing and automations in Live usually carry me through.nathannn wrote:not for me it doesn't.

Re: Multicore support needs a big overhaul
@pencilpenis well yeah im a noob to edison i guess. but that video dont show what im talking about... basic non destructive editing.

yeah i agree with you 100 percent, like i said this is why i really cant go back to fruity.H20nly wrote:i can't stand the way FL handles audio.
