Hi, I just installed my old Pulsar-card in a new computer and now everything seems OK but when I record the sound comes out all crackling and slightly sped up.
I sought help in another forum :
http://www.audiomastersforum.org/amforu ... 7934#27934
and they sent me here.
I hope someone has experienced something similar and can give me a clue as to what to try next.
new computer, new problems
That's a sample rate issue, I would guess.
Somehow you are recording at one sample rate and playing back at another. You may perhaps have an IRQ conflict as well, if things are playing back noisy.
Please give us the specifics of your computer system and Pulsar card. Which slot is Pulsar installed in, and can you check for IRQ conflicts.
What sequencer program are you using? What sample rate and bit depth are the sequencer and the Pulsar card set to? Who is the master/slave clock? Pulsar, or computer?

at nprime: No, it's not a sample rate issue as far as I can see, I checked that. The IRQ-thing is maybe something to look into. But what's an IRQ-conflict and how do I check it ?
I'm using a wave-editor primarily (Adobe Audition) and I really don't use much of all Pulsars bells and whistles. I do use Pulsarsynths (like Minimax) but I record them as audio.
I explained a bit about my system in the other thread. The thing is, This a brand new computer, and I installed the damn Pulsarthing with the latest Scope-software and still it doesn't work correctly.
In the meantime I have been able to record cracklefree by changing the Ulli-setting, but now I try to record a standalone VSTi, which I could on my old system without problems, and there are the crackles again. And changing the ULLI-setting doesn't help this time.
at dubcotics: I disabled the hyperthread thing in the BIOS, but it didn't help. But thanks for the suggestion.
More suggestions anyone ?

Hi there,
What are your system specs?(don't know where the other thread is)
You can check for IRQ conflicts and sharing in 'system information' on XP. Go(programs/accessories/system tools). If you run in standard PC mode you can then change IRQ settings in the BIOS. You could also disable hardware you don't use in device manager, if they share with your CWA card.
If you don't need USB2, disable that in the BIOS as well.
It could also be onboard LAN, graphics card or too little RAM, I recommend at least 1 Gig.
Have you checked that you've done all your musicXP tweaks?
Good luck. Let us know what happens.

You can find the other thread through the link in my post. But it's a brandnew Dell Computer (Dimension 8400 Series) XP, more than enough RAM and harddisk etc.
OK in syteminfo I find:
IRQ 17 Intel(R) 82801FB/FBM PCI Express Root Port - 2662
IRQ 17 Creamware Pulsar
and there's another list with the IRQ's from 0 to 23 and in status it says OK for all of them.
Now I don't know what to do with this info.
Should I try to move the card in another slot. And if I do, will I have to reïnstall the software too ?

If the audio is slightly sped (and pitched) up it can't be other than samplerate mismatch. The only way I know to play a file with a different speed/pitch without processing it is to have a different samplerate in playback.
This doesn't necessarily mean that you have crackles, but you could have an app that doesn't sync properly with scope drivers, in wich case you may well have that....

Exactly the same problem with my new Dell Dimension 8400.
Applied all the hints and tweaks.
No IRQ conflict (18).
It sounds like the computer is not recording all the samples, but from time to time skipping a few.
What's the solution???
It must be a Windows XP / resource issue, since it works well on the same machine under Windows98se.

Few more things to try:
- Disable USB in the BIOS. Not a permanent solution, just to see if that helps.
- Tweak PCI Latency, both the general value in the BIOS, and individual devices' latency. I tend to put general value at 64 (including videocard) and Creamware cards at 96 or 128.
- Turn off that dllcache thing, themes, the new stupid candy-coated (and pretty ugly) XP, screensaver, etc.
- Use the IRQ priority tweak (more info here http://arstechnica.com/guides/tweaks/sgp-tweaks.ars) to prioritize your soundcard's IRQ.
- Install XP in Standard PC mode. People say this is not necessary with newer machines, but I installed XP in Standard PC mode on my new AMD64, and it works like a charm. I have no trouble recording and playing back 32 channels (+ tons of reverbs) at the lowest ULLI setting. Just turn off all the stuff you don't use in the BIOS (serial, parallel, onboard audio, etc.) I turned off USB on mine, since I don't use any USB device, but this isn't practical for everyone. So if XP in ACPI mode (the default) doesn't work well for you, Standard PC mode is definitely something to try.

Agreed that it might be the Dell + XP combination. I have no idea why anyone would buy a Dell machine for a DAW. Sounds more like straight flakey hardware to me than an actual XP + HW conflict =P The drivers Dell provide with their machine is absolute total garbage.
If you feel a bit courageous, I suggest opening up the machine and looking at the chipset/motherboard and figure out what hardware vendor build the motherboard, and use the drivers provided by that manufacturer and not Dell. This has worked pretty well for me the (thankfully) few times I had to do techsupport on Dell machines.
Otherwise I know plenty of people using XP for audio, on a pretty large variety of platforms (P3, P4, AMD, AMD64) and soundcards (M-Audio, SoundBastard, RME, Lynx, Creamware) and none ever reported any problems, and all agree that it's the best version of Windows for audio. I've never seen 98/Me do anything besides crash and burn after a few months, however careful I was.

I would start by format and redo Win XP fresh.
Preloaded OS's on new system dont really work most of the time.
There is nothing better than putting a fresh XP install on that machine.
Also note that you need to make sure there is no conflict with other devices. (check IRQ's)
Make sure you are loading a recent version of Pulsar software (3.1C or 4.0)
You may want to give a list of IRQ in your machine.

Hi symbiote
I agree with you,beside i have buy my computers in PARTS I asembled it myself that offer me the chance for it's quality for the audio productions,& i doe's the same to friends arround me.
Im using win.me for some time now no craching,some times the system stay on for the following day without resetting.
to say more,good system depends on the installation procedure,always hhd partition b4 format,after win installations mobo drivers must,follow by v.dio card drivers.
cheers
