Hello guys !

Well, i'm trying to record a guitar track using Guitar Rig 2 VST plugin in Cubase SX3.

I'm using ASIO2 24 bit device with 4ms ULLI in the Scope Project.

Before recording, no problems, and the CPU Charge is very low.

Do you think that the problem is because i've got only one hard disk ?

Could it be resolved adding a second disk, even if this disc is an IDE one and not a SATA one ?

Any suggests ?

try a lower ully
set cubase at high priority in device setup
maybe if you uncheck multiprocessor box in cubase will help.
i don't think that one hd is bad.
actually more reasonable is to have 2.
1 for os and 1 for recording your projects.

forgot to ask.
what pc do you have and how many programs installed except scope and sequencer?

thanx for reply

ok, i tried at 18ms ULLI it's better but there are always some crackles.
what do you mean "set cubase at high priority in device setup" ? Do you mean that audio must be in high priority in expert mode of the device configuration (cos it's like that) ?
multiprocessor box is already uncheck.

Furthemore what model of hard disk do you recomand ? not too noisy of course ...

thanx

hard drives?

i've got a Sempron 3400+ PC with mobo chipset nForce4. I've got a Pulsar I and a Luna II card. 150Go SATA disk.
i've got a lot of things installed, but when i'm using it for music, i desactivate all resident programs (even and also anti-virus) and ethernet card is also desactivated.

In this project i only use guitar rig 2 as vst plugin.

nforce4 is is very bad for daws with most all cards. there may be a bios update that addresses the problems.

basically, that chipset is designed for maximum video performance with games and such and handles audio poorly. many others have had bad results, sorry to say. intel core2 is flawless by comparison. there have been those who have reported decent results with later nforce4 mobos.....

ok, thanx for your replies ...

I tried to desactivate all the things i don't need in the mobo (network, ac97 chipset), and on this mobo (K8N Neo3), there's no possibility to play with PCI latencies.

I had download a tool called Doubledawg and it gives me 096 for the Luna and 128 for the Pulsar I, but i think this tool is for adjusting the PCI latencies for video cards.

The problem is that for PCI Express Cards, there's nothing to do.

I could PRAY a lot, but i'm afraid there's nothing to do to solve this problem.

So i suggest to the people who have no problem with their setup to tell me the mobo they use. Perhaps a topic about "No problems users" would be fine to help people who want to change their config ?

set highest priority within cubase.
as you said you have a lot installed.
keep in mind that you must set the system to boot without loading applications and then after reloading them, cause there are a lot unusefull things running still, or stuck in ram, even if you have set the system to always unload dll from ram(necessary absolutelly).
set it this way so the antivirus and all other progs not to start with windows.

i will ask you something else: check task manager and see how many applications are running at the time you think everything is ok for audio.

a few minutes ago i made this optimization of disabling unusefull services in xp in my new instalation.

clean the system with xp tools you think are ok for your pc, i use cccleaner and regseeker and i also defragment with diskeeper.

guitar rig is not a light vst.
you said that the cpu usage is low.
check it when you have loaded the vst plugin.
there is also an option in guitar rig of disabling the high resolution(its a button that shows cpu usage),(the sound is not that clear, but it is ok if your system cannot handle with much cpu load).

i have this problem somtimes, it has been happening a lot recently driving me mad, the thing is it hasnt always happened, my system was stable for a while

my software is slightly older but problem is essentially the same, I have win 98 & vst 5.1, & playback is perfect but on record I get random glitches, if I try recording 3 or 4 times I will eventually be able to record without a glitch, but as you can imagine this is annoying. i have tried recording cubase/sfp output into wavelab, & STS5000 & get same problems, recording back into cubase seems to work best. SFP is on largest latency, win 98 is optimised for audio, computer is almost exclusively used for audio (very occasional photoshop work as well)

two things occur to me, one my 80gig hard drive is getting close to full, would this cause problems?

secondly the glitches seem to get more the longer I have the computer on, could it be temperature related? I read on another forum someone vaccumed/dusted their pc out & temperature of pc dropped 5 degrees (maybe I will try this, careful not to touch anything of course)

an 'almost full' harddrive is almost certain to fail on recordings, as it has to 'hop' to the next free segment that's displaced on the disk, data accumulates, then that segment is filled, it has to hop again and so on.
Continuous writing isn't possible anymore.
Easy to cure as drives are cheap these days and usually faster than the 80G versions, too.

heat dissipation in 'standard' PC cases is indeed rarely optimized, but a brute force attempt with a vacuum cleaner looks (and hears) a bit over the top imho

with some reasoning (you have to analyze the particular sources and airflow in YOUR setup) and quality fans it's not such a big problem, though I found it rather time consuming to apply changes to an existing setup.

harddisks are often overlooked as a heatsource, as there's often no airflow over them. You may check that when you open the PC after it was on for a while and touch the disks.
The inside of a PC is really not too sensitive, just avoid touching contacts.

I'd certainly raise the ULLI value; having 4ms set is going to place quite a bit of work on the CPU. I've got mine set to...er...well, whatever the default is! 19ms?

Another disk can't hurt. IDE is fine; modern IDE drives are very fast. I use a separate disk for audio recording. Another trick is to move the Windows swap file away from the system disk.

Have you tried this yet:

Worked very well for me (don't know if it's still an option in SX3 though as I'm still on SL2).

thanks for replies, I will get new hard disc, & I think finally upgrade to xp - cos I was looking at various cubase options last night & decided that I might not have enough RAM for the number of audio tracks I am trying to use (I have 500mb, I have another 500mb not currently in the computer, cos win98 can only handle 500)

bigdaves prob might be different afterall, but as already mentioned first thing I would try is increasing scope latency

Iskra:

How are you dealing with this problem now?

I am experiencing the same while using REAPER. Playback is fine, even on 4ms ULLI, but recording is a bitch at 23ms even. Though playback sounds worse than what I get recorded to file.

The problem seems to get worse as I add more ASIO-sources/dests.

I've thought of hooking my two Pulsar II's up the suggested way with the STDM (pin 1 + pin 3), to properly terminate the cable.

Also, I will check my PCI latency and eventually set it higher.
Thing is, I get the highest MasterVerb test scores around here.

I will fool around with REAPER priority setting, as well as setting Scopes settings lower.
