reason DPU problem

Hey, I', having the old problem again with Reason maxing out. The DPU is going into the double red zone causing crackling sounds or like a cd skipping. I had my computer adjusted so that it could handle more by turning of a bunch of processes that I wasn't using, even the graphics. I looked in the task manager/process and there is only 4% CPU being used other then Reason. Reason is taking up about 50% CPU when the song's DPU is maxed out into the red. In Reason's preferances i have it so the CPU reason can use has no limit. So why isn't it using the computers full CPU instead of just 50%?.

My comp has 2GB RAM, can't remember what kind of processor though. It's driving me nuts. In one song i started deleting tracks and merging tracks to free up some space but it actually did the opposite.

Most likely a sound card problem. Check your drivers, your buffer length. i am not to knowledgable on the topic.

i have an M-Audio sound card, and the buffer length (that's like the latency of when you hit the keys right?) is kind of delayed already.

Okay I had a M-audio firewire 410 and it was junk! Did not Let me run Live or Reason in stand alone mode! But For some reason it worked Fine rewired in to protools! so i got rid of it!

Get a new Sound card I been there!

the only soundcard that is running anymore is the m-audio one. you think that will solve the problems huh?. i meen it's fucked that the dpu is full in reason but the computers actual cpu still has almost 50% free. can anyone suggest a good soundcard then?. one that will let me us 100% of my comps cpu?

this is what i have now , M-audio fast track

Erm if reason says 100% but your computer says 50%... are you running a dual core cpu? It makes sense that maybe reason is just running on one core.

yeah the computer processor is a AMD dual core i believe, maybe more but i doubt it.

i remember someone at best buy said that reason can only do so much becuase it uses it's own processor and that getting a crazy mac computer wouldn't solve my problem. not too sure how much i believe him though

i think this is it, or pretty similar, i remember the processor being 9000, or 6000 something. not too sure though

Reason "uses its own processor?" Sounds like the dude from Best Buy was talking crap...

hahah yeah something along that line , but don't quote me. basicly he said that reason can only do so much even on the best computer

no, move your buffer up on your soundcard. try like 512 or higher

Eye, sounds like reason is only using one core then. Hence the 50% in task manager and it saying it's maxing out.

Remember also a higher sample rate=lower latency but the same buffer size so the same cpu use(or maybe not quite, but it's better overall). Try setting the buffer higher, and if the latency is too high set the sample rate higher.

Sorry but turning sample rate up would increase the CPU load as it has to process more samples per second to produce a proper output.

Furthermore I think only Reason 4 has proper multi-core support (not sure). And it (used to) have problems with intel hyperthreading as well, I'm not sure if that's still the case, or if multi-core processors even use hyperthreading nowadays. My bet would be that Reason uses only one of your cores. If you see the CPU usage meter in Reason freaking out while task manager says you only use 50% there's obviously something going wrong with Reason and the multi core processor.

reason 4 is atleast supporting 2 cores, more i dont know. try downloading asio4all and see whether that helps or not. set sample rate to 44.1 and buffer size to 1024 (23ms) in reason preferences. also look at how to make your tracks more efficient (see manuall, i learned a few tricks there). and what comp are u running? Im on a 1,83GHz Dual Core Mac Mini 1GB Ram now and have no problems, my most complex track as of lately (around 20channels) runs on three dots in the DSP loadbar.

Well I'm saying that if I over 3x my sample rate to 192khz then I only need to slightly increase my buffer size (say 30%) which is still a much lower latency overall.

how can this be, i just tested a track i made ages ago which ive had problems with later on, cou maxing out etc. now that i opened it on my mac mini it just works without any problems. my other comp is 2,4GHz (i think) QUAD Core with 4GB Ram, this one is 1,83GHz Dual Core with 1GB Ram and this one works much better? on Reason that is. i think theres something strange about the DSP meter in reason, atleast it does not seem to have much to do with actualy CPU realy, maybe its a combination of CPU use and RAM use????

Well when I mentioned I only had to turn buffer size up 30% that was with me playing a single note to see whether there were issues (however, I've gotten up to 32 note polyphony on a complicated patch before issues with this setting however).

I mean hell, with an e8400/gigabyte ep35 whatever ds3 which I bought for gaming, I can get 4ms latency with just the onboard sound and no asio support (using dx).

what can i do about this?.

what is asio4all?. i will try setting thoughs rates and see if it helps.
i have been trying to make my tracks more efficient. i'm using the send/return, and using the nn-xt for multi fx isntead of loading one sample per nn-19. plus i have been trying to fill out the redrums better.

i sent my file to a buddy, im just waiting to hear back and see what he thinks.

thanks for the advice guys, still kinda stuck though

I just tested the cpu performance on my computer (2.2ghz dual core) running Reason 4 maxed out and its doing the same thing! CPU meter only shows about 50% when Reason is at 100%.

Reason only use ONE core for it�s audio. Imagine writing a code that would support dual core cpus, with that wiring system.
Not saying it couldn�t be done, but it would be a overwhelming task, to say the least.
This has been explained by Prop�s programmers.

so bassicly i have out grown reason as a stand alone device?. every song i do either gets close or does max out. fucking reason hahah

seriously post a pic of your tracks, i have no problems what so ever with reason on my current PC, so i start wondering how much shit u got in your tracks.

Is there a way to take a screen shot of the entire vertical part of reason, not the playlist but for example all the devices in all the combinators i have.

I dont know how to take a picture of my screen. I have lots of shit going on in my track. probably too much but if my computer CPU can handle it why not reason's DPU?. I don't thinks its my computer that's the problem it's reason. so I should be able to use more devices, right?

I'm having the same problem as Stealth with reason only handling 50% of my comps cpu. It's driving me nuts, there always seems to be a problem with the DPU.
