As I posted previously I'm getting sound glitches and stuttering with projects that don't have effects and system freezes and lockups when I do use buses and effects. I've reinstalled the entire system but I have yet to update the bios. Would/could DirectX 9 make any difference - or is trying that just asking for more trouble? Is it at all possible that it could solve my problem? Chris (Hunt) System specs (again!) Windows XP Pro, Pentium 4 2GB, 1 GB Ram, Audigy Ext, Radeon 8500DV videocard, drivers up to date I have plenty of hard disc space and I defrag regularly |

from your specs you shouldnt be having any issue with stuttering.... might be the soundcard[?] |

Knowbody... DX9 is still "untested" with alot of apps[I mean ofcourse A/V apps like acid/vegas/sonar]...If you like to be a tester for us all go right ahead ;) but I would NOT recommend it. If it doesn't work now it will probably get worse if you did. Should first update your bios. Plus please get rid of the soundblaster!!! M-Audio/Echo/etc... When you say..."I have plenty of hard disc space and I defrag regularly"---Do you mean that you have your system is set up with TWO harddrives: 1)OS 2)audio drive? Or do you store ALL your audio on the same HD as the OS? [Not good if you do.] How fast is your HD? 5400rpm/7200RPM? Windows XP Pro [WITH/WITHOUT?] service pack 1? What other software do you have installed AND/OR running in the background? Is your OS setup for "Standard PC" mode? [important] Ed. |

I'm experiencing audio stuttering as well: -Running WinXP in Standard PC mode, SP1, background services enabled, etc -1.8Ghz -1GB RAM -Two HDs (one for OS, other for music data) 7200RPM / ATA100 -Stuttering on MOTU 828, and most recently the EZ8 ADAT card (connect to my digital mixer) -Bios updates, all driver updates (video, motherboard..etc) -Running Acid Pro 4.0b, Wavelab 4, Sonar 2.0XL I really don't know what else to do. I usually get stuttering/lag when using Direct X drivers from SONAR in Acid but not all the time. I've messed around with buffer settings until I'm blue in the face, reinstalled the OS a number of times to get clean installs from soundcard to soundcard...stuff like that. It's getting to the point where I reevaluate whether or not to use Acid all together.. Thoughts? Help? Anything? DJ Butterface (info@djbutterface.com) |

Motu is NOT the brand to use on the PC platform. I would recommend getting something else and see whats up. I think there is someone here that uses motu gear [macmoney?]so I hope that they can chime in and help. I don't use motu stuff on pc because of ALL the problems that I've read about them on the web. Get the Sonar 2.1 patch so that you can benefit from all the fixes that were done[and it was ALOT!!!] What do you guys have at the bottom right corner of your screen[ie:what is running all the time]...All I have is a icon for my "contour shuttle pro" and one for my "microsoft trackball explorer" thats it. Do you guys have ALL your XP GUI enhancements turned off? ie: windows classic style Try>>right click desktop>properties>>appearance>>>effects>>>>anything checked off????? The only one I have checked is the last one on the bottom. Doesn't seem to be as important as the rest. Your system is 3times as powerfull as mine and I don't have stuttering probs. HTH. Ed. |

I have all the XP effects turned off, and im in classic mode. I don't have anything else in my system tray running - no trackball explorer or anything. I pulled the Motu 828 off my system a few days ago, and yanked the firewire card from it as well. Instead, I'm using Event's EZ8 ADAT card which allows me to connect to my Fostex VM200 digital mixer via ADAT lightpipe, using their XP drivers. |

Thanks for the suggestions, Ed. I do have a seperate hard drive for audio - 7200RPM. I have Service Pack 1 installed. I have all the GUI stuff turned off and I'm in classic mode - that bright bubbly XP interface gives me the creeps. I do have some small appications running in the background, including a virus checker. I switched them all off and tried but it didn't make any difference and shouldn't. As you suggested there is no way I should be having problems with these specs. What do you mean about "Standard PC mode" is there a setting for this? Thanks, Chris |

I switched them all off and tried but it didn't make any difference and shouldn't--I'm not sure of the exact reason why it shouldn't be installed but its worked for me and others. I've got this advice from other forums as well like cubase.net. People were trying to run cubase with "nortons system works" on it and it gave people the weirdest probs. My recommendation would be to "partition" your OS drive 2-4 times[max] so that you can have one OS for fun[internet/games/email/firewall{zonealarm}/nortons{antivirus,etc...},and the others for work...ie:audio/video apps like acid/vegas/sonar/etc... What do you mean about "Standard PC mode" is there a setting for this?---The problem with XP and "single" processor systems is that windows would like to throw all of your hardware on one "irq" #9. Thats because when you initially installed the OS it by default sets it up in "ACPI mode"...sorry I can't remember off the top of my head what that stands for. For day to day stuff I guess it works but for specialized applications it causes problems. Do this... start>right click "my computer">>properties>>>hardware>>>>device manager>>>>>file-view--resources by type---irq. Do you have your soundcard "sharing" a irq with anything else? If so then there is at least one of your problems.[My echo layla 20bit soundcard is by itself on irq number 11. To setup your PC for standard mode you need to do a fresh install unfortunately. And to do it right I would format the drive clean so that there are no errors. To do this... 1)First format your drive. 2)When the OS installation starts you will see a dialog at the bottom come up saying something like "press F6 if you would like.......". Sorry I haven't done a install for a while so I'm not sure of the wording But I'm sure that you'll see the F6 there. When you see it say F6 PRESS F5 IMMEDIATELY!!! Later in the install it will THEN give you the option of selecting what mode you would like...ie:acpi,standard pc,not sure what else. 3)select standard pc...;) Another thing you should do is "disabling" anything in your device manager that is not being used so that your OS has more free irq's to play with. Since everything on my computer is connected to my computer by "USB" I've disabled my "com1+2" plus my LPT port...I have my HP deskjet 5550 printer connected via usb as well. Make sure you remove all your hardware from the PCI slots first then add them one by one after the installation so to make sure there aren't any conflicts. ie: nothing important should be sharing a irq. ie:soundcard and firewire card/USB 2.0 card. On your A/V partition first install all your OS/driver/latest bios for your motherboard/etc...updates then install all the apps with the most current version. ie:acid 4.0b,sonar 2.1,etc...DO NOT INSTALL ANY CRACKED SOFTWARE. If you do then everything I've just mentioned could be useless because neither one of us can then pinpoint if thats causing the problem. Plus cracked software is wrong and it creates a "window" into your computer for a hacker/@$$hole to ruine/steal your work/mess up your registry. Even if you've installed a firewall and virus scanner as well. [not to say that you do use cracks though...just being thorough] HTH. Ed. |

I am not a Acid 4.0 fan, Sonar is 10x more stable and more capable but.... be sure and check that your hard drives are set to "DMA". XP has a way of setting them on the slower (PLO)setting by default. |

I keep seeing problems like this, and I'm having it on one of my machines. From what I'm reading I think mine might be a "denormal bug" that is found in p4s, and it seems to relate specificly to plug-ins. I did a search in the forums, and downloaded a denormal program and a vst wrap. we'll see how it turns out. |

Somebody here posted a link in another thread that had some excellent information on optimizing XP for audio. However, in that information, they strongly recommended AGAINST installing as Standard PC unless you had conflicts you couldn't resolve any other way. So what's the advantage of installing as Standard PC? Can anyone here tell me? I'm installed as APCI and am having no problems. |

to answer the original post, installing DX9 seemed to have little or no effect on ACID's performance on my system. (win2k, sp3) it already works ok though, although i've seen the denormal issue you're discussing and some strange behavior related to that for sure. |
