Well I do get some clipping noises & unwanted noises even on my Mac.The Mlan interface that comes with the Motif seems to be the cleanest I've used so far but they are way too complex & you would have to keep your keyboard on throughout your project.

Holy crap. Just buy a mac and you will not have to do all of this stuff. What a waste. So you can build a cheap machine. So what? If the cheap machine has a junk OS, what good it it? People blame many of their DAW woes on the DAW coders, when most of them have 10 or so systems operating flawlessly in their design departments. Windows is a complete joke for an OS anyway. The only Windows DAW I use is SAWStudio and the live Software Audio Console. The reason I use those on a PC is because they are coded in Assembly Language that by=passes Windows for the most part. For everything else, Apple Macs are IT.

Normally, I steer clear of statements like those above as they are, in my opinion, intended solely to incite negative comments and flame wars.

With that said...thank you for your opinion. And I don't necessarily disagree with you. I have on many occasions, in these forums and others, given a positive opinion of the Mac product and I stand by my opinion. It is an excellent product.

However, there are many who already have Windows based computers that they are trying to get working with DAW and interfaces rather than spend the extra money that may not be available to everyone in the current financial climate. This thread is an attempt to assist them. The capabilities of Apple systems are well documented on this, as well as, many other computer based music production websites.

The logic here is that the majority of computer users are using Windows operating systems, especially those just getting started. Opinions aside, they still need help in many cases to achieve functionality in the computer music production realm. That is the sole intent of this thread.

I very respectfully ask that any who visit or post to this thread please try your very best to keep it geared to the topic at hand.

With all due respect, you are not selling this stuff like we are. You have your experience to deal with. We have the experiences of hundreds, if not thousands of DAW customers to deal with. We know what is easier for the customer and what is not. Macs are almost always a better solution for Studio One, VSL and Capture. Mac customers seldom if ever have any hardware issues. The issues have been all on Presonus' side. When it comes to PCs, we have to go through pages of docs like those posted here, and do all kinds of prep work, before we can address the DAW issues.

Again brent, I don't necessarily disagree with you.

I'd like to think that the hours I spend on this forum almost every day justify my reason for starting this thread and trying to keep it updated. And believe me, I do spend hours on this forum trying to assist as best I can. It isn't a business for me but just a way of giving back to those who have been helpful to me. I use this as a reference and a tool to assist people.

The point of this thread is to help those who don't have macs to either help themselves or help others.

EDIT You're right, I'm not selling this stuff. I have nothing to gain. If I were making any profit from this then it wouldn't be here. It would be on a separate website that I am paying for. Why would I give out my assistance for free when I could charge people to call me or send me their computers. If you are selling it then sell it the way you and the customer think is best suited for their purposes. I have absolutely no problem with that and I wish you the very best of luck with it. I have on several occasions found the problem to be the device as well and recommended that the user have it repaired. However there are far too many who automatically blame the wrong piece of hardware or software for the problem. Windows sucks as a DAW platform for the most part, but that is all the more reason to justify why I do what I do. It can be fixed and equally, if not more powerful that a mac. There are companies who have proven this. EDIT

I can't, in good conscience, just tell someone who comes to this forum looking for assistance to just go buy a mac after they already own or intentionally purchased a PC, and leave it at that. Though, as I've said on many occasions, Macs are excellent machines for computer based audio production purposes. The reality is that there are many who already have or intentionally purchased PC systems who may not be able to afford or may not even desire a changeover to Apple systems. So in the meantime they have to or choose to use what they have at hand.

This thread is here to help people. Simple as that, and all I ask is that it be kept close to the subject at hand and be expounded upon with useful information.

If you'd like to discuss this further feel free to send me a PM and we can discuss there. We aren't exactly on different pages but I'd like to keep this thread on topic as much as possible.

It's not just your hardware,

it's software (operating system plus every single other thing you have installed)

Best thing for you to do is download at least one of the latency checker software programs referred to above.

Install and run them and tell us what you get.

However this thread is for general suggestions for improving your Windows operating system

For a specific diagnosis of your computer only, I suggest you start a brand new message thread (can link to/from here).

When i had Windows XP i had some crackles during using vst-plugins.
But sometimes changing the sample rate helped with it.
Now i have just installed win7. I have crackles even during playback.
I've installed latest driver for firebox (5.13), updated 1394 driver (tried both latest and legacy versions)
updated all drivers in PC (motherboard,...) but nothing helps.
I reinstalled all drivers several times.
I tried almost everything.

The solutiion was to update BIOS.

Your link to the TCAT DPC checker got me to a dead end (maybe it was just too long to copy or I made a mistake). A short version that's easier to remember is:

http://tinyurl.com/Download-TCAT-DPC-Checker

Click on the file name in the directory and off she goes.

By the way, on this (not-usually-music) computer, it showed a spike every few seconds. Disabling the network adapter resolved that problem. Now, gimme that 64-channel StudioLive, I'm ready. But, darn it, I can't Tweet after every take in the session.

TC Technologies keeps moving that silly thing around.

The Latency Mon from above is the new preferred tool unless you're on an XP system. I will see if I can't dump the other one in as a file to download from here instead of a link. It'll be tonight, though. I can't access it from the office computer.

I've been trying to get Presonus to pony up to the 64 channel version but it exceeds the capabilitites of the firewire. How bout a 50 channel and a submixer?

I tell them my case, search and solution to connect my motherboard firewire pci express card to my computer and make the link with the Studiolive2442 and recording in 26 ch (24ch + L and R)

My Team:

2442 StudioLive

1.0 The original driver 167, but installing the software that came with the purchase is the "downgrade" to 0.97 164 (?) ... Even I can not go to update, I downloaded the UC 1.2, but updating the firmware, this hangs and even lost all factory presets and scenes ... I could only recover after several attempts and return with the UC 0.0

ADS Pyro Firewire Express card API654 (2x800) TI chip

Lenovo S10e Netbook:

1.6mhz Intel Atom - 1GB RAM - 160GB HDD - Win XP Pro

PCI Processor: Intel 82801G (ICH7 Family)

Video Processor: Intel 945 express family

Just insert the Firewire board is installed ok. By connecting the StudioLive is also recognized I installed perfectly.

When you open the Capture or UC is not visible StudioLive, although it appears in the list of audio hardware at all times.

Until now I thought I had read all about the problems with this type of connection, both here and elsewhere ... to find myself in trouble again .. I kept searching and reading ... (there are many variables and issues to which they could not work ... and many more sites that exist on the subject ..)

After disabling everything related attempts to chip 82801G (wireless card, usb ports, network board sound board ... also, Bluetooth ....) Closing programs (antivirus, etc) and reconfiguring the startup items not to get results.

By using the software suggested in this forum for check Compatil FireWire (OHCI TC Applied Technologies Tool https://dev.tctechnologies.tc/tcat/tags/release/pu...ool/Win32/Release/ohciTool.exe ) tells me that your hardware is compatible ... but .... I also notice a file "SidSpeed" in the Windows registry, missing or corrupted, and can thus not the 1394 driver work fine ... at first I assumed that this is not a problem, so I kept trying more configurations for hours ... finally back to this file and I search on google I find this patch on the Microsoft website to this topic:

"It can decrease the performance of 1394 devices after installing Service Pack 2 for Windows XP

http://support.microsoft.com/kb/885222

This link explains how to correct this problem, so once done, try again ...

and .... finally! The StudioLive appears in both Capture and UC .... I could not believe ...

Once so, testing began recording and latency, where at first it was very slow ... movements in the UC console, faders, and the recording was not complete, only a few seconds ago by locking the cursor every 3 seconds .

The solution came after making the following:

Latency Test with: http://www.thesycon.de/dpclat/dpclat.exe

Reconfiguration of startup files and services are not important

UC Configuration SAFE mode 3 - 4096MB

Thus, the recording and operation of the StudioLive work perfectly, even when the limit or below the resources of hardware and software that suggests Presonus netbook (small).

All this I tried playing a music file in Windows media player from the miniplug audio output 3.5 ch entering them in 1 and 2 and made ??the StudioLive 24ch record from the same netbook! Lenovo's amazing that I support this!

Even more, I did not need to disable the wireless board or other components to achieve the solution.

When you read Microsoft's explanation regarding SidSpeed ??file will not be able to believe that even after taking my pc the service pack3, which could cause many problems.

I hope this article will serve as a solution to more than one person.

Regards

Nicholas

Odisea firewire….

Les comento mi caso, búsqueda y solución para conectar mi placa firewire pci express card a mi equipo y lograr el link con la Studiolive2442 y la grabación en 26 ch (24ch + L y R)

Mi equipo:

Studiolive 2442
El driver original era 1.0 167; pero al instalar el soft que venía con la compra este lo “desactualizó” a 0.97 164 (¿?)… Aún no puedo volver a actualizarlo, he bajado el UC 1.2, pero al actualizar el firmware, este queda colgado y hasta perdí todos los presets y escenas de fábrica… sólo pude recuperarlos luego de varios intentos y volver con el UC 0.0
Firewire Express card ADS Pyro API654 (2x800) TI chip
Netbook Lenovo S10e:
Intel Atom 1.6mhz – 1gb RAM – 160gb HDD – Win XP Pro.
Procesador PCI: Intel 82801G (ICH7 family)
Procesador video: Intel 945 express family

Apenas se inserta la placa firewire esta se instala ok. Al conectar la Studiolive también es reconocida he instalada perfectamente.
Al abrir los programas Capture o UC no se hace visible la Studiolive; aunque sí aparece en el listado de hardware de audio en todo momento.
Hasta este momento creía haber leído todo respecto a los problemas con este tipo de conexión , tanto en este como en otros foros… al encontrarme nuevamente en problemas.. seguí buscando y leyendo…( son muchas las variables y cuestiones por las cuales podrían no funcionar… y muchas más las web que existen sobre el tema..)
Luego de intentos deshabilitando todo lo referido al chip 82801G, (wireless card, usb ports, network board … también sound board, Bluetooth….) cerrando programas (antivirus, etc) y reconfigurando los elementos de inicio tampoco de obtienen resultados.

Al usar el soft sugerido en este foro para el chequeo de compatilidad de firewire (TC Applied Technologies OHCI Tool https://dev.tctechnologies.tc/tcat/tags/release/pu...ool/Win32/Release/ohciTool.exe ) me comenta que el hardware es compatible, …pero…. También me advierte de un archivo “SidSpeed” en el registro de Windows, perdido o corrupto, pudiendo de esta manera no funcionar bien el controlador 1394… en un principio no supuse que esto sea un problema, así que seguí probando más configuraciones por durante horas… finalmente vuelvo a este archivo y lo busco en google donde encuentro este patch en la web de Microsoft con este tema:

“Puede disminuir el rendimiento de los dispositivos 1394 después de haber instalado el Service Pack 2 de Windows XP

http://support.microsoft.com/kb/885222

En este link explica cómo corregir este problema, así que una vez realizado, vuelvo a probar…
y…. al fin ¡!!! La studiolive aparece en ambos Capture y UC…. No podía creerlo…

Una vez así, empezaron las pruebas de latencia y grabación, donde en un primer momento todo era muy lento… los movimientos en la consola UC, faders, y la grabación no era completa; sólo lo hacía por unos segundos trabándose el cursor cada 3 segundos.

La solución apareció tras realizar estos procedimientos:

Test de latencia con: http://www.thesycon.de/dpclat/dpclat.exe
Reconfiguración de archivos de inicio y servicios no importantes
Configuración en UC en modo SAFE 3 - 4096mb

De esta manera la grabación y operación de la studiolive funcionan a la perfección, incluso estando al limite o por debajo con los recursos de hardware y software que sugiere Presonus (netbook muy pequeña).
Todo esto lo probé reproduciendo un archivo de música con el Windows media player , desde la salida de audio miniplug 3,5 ingresándolos en ch 1 y 2 de la studiolive y puesto a grabar en 24ch desde la misma netbook ¡!! Increíble que mi Lenovo soporte esto ¡!

Incluso más, no me hizo falta deshabilitar la placa wireless ni ningún otro componente para lograr la solución.
Cuando lean la explicación de Microsoft respecto al archivo SidSpeed no lo van a poder creer, que incluso tras tener en mi pc el service pack3, esto podría ocasionar tantos problemas.
Espero este artículo le sirva de solución a más de una persona.
Saludos
Nicolás

Thank you very much for contributing.

I've been meaning to do an update regarding SidSpeed but have not had the time or not remembered to write it when I did have the time.

It makes me quite happy in a another regard as well. I have a Lenovo S10e that I've been considering trying to connect via firewire card to one of my StudioLives. It's good to know it will work.

To make this a little easier for everyone to figure out
SidSpeed is effectively what tells the firewire bus what speed to operate.

When the OHCI Tool is run it will tell you is SidSpeed is good or not.

If it is not good then there is a MS Knowledge base article that explains how to fix the problem (listed in the post above)

If SidSpeed is not functioning properly then there will be no firewire connection (which is why I ask most people to run OHCI and post the results)

Again, thank you very much for adding this in here.

OK Boys and girls,

It's been a while since I've made any updates to this thread but I found a good one to add so here goes.

User tomfrost brought in a link that has him at least functional with Presonus interfaces on a Ricoh chipset firewire. I have not personally tested this yet so your mileage may vary.

Also, this is not from Presonus. Avid did some work with Ricoh and they developed a patch that helps Avid folks use their firewire interfaces on Ricoh chipped systems.

Here's the link to go get it [url]http://avidqa-dev.custkb.com/avidqa/app/selfservice/search.jsp?DocId=357477
[/url]

From my understanding, you have to have this running before you fire up your DAW and control panel. It won't work if you don't.

When I get a chance I will test it and see what I can determine but it'll be a while since I have a lot of other work to do right now. Until then understand that Presonus does not directly support this and won't be held responsible for any potential harm it may do and I have not tested it either so I don't even know what it will do. I have to find another cheap system witha Ricoh in it to test and that cold take me a while.

Cheers!!

OK boys and girls, a couple of new ones.

First off, finally something for the Apple people!!

This one is not my work, the only thing I know about apples for certain is that when sliced and mixed with sugar and cinnamon they make a great pie filling.

So here goes and thanks to forum member npatwardhan for doing all the work on this. It's essentially a streamlining technique for macs to help you get a bit more capability from them.

My 1986 Buick Century exhibited a propensity to not start when it was damp/wet outside, and to stall repeatedly once I finally did get it started, was stopped at a light, or took a curve over 25mph, etc. I took the car to a shop who was recommended to me (what the hell did I know about referrals or anything since I was only 19?!). After swapping in a bunch of parts, the car continued to stall. I replaced all the plugs and wires. Didn't help. Finally they replaced the distributor cap and the car never failed to start again. This didn't stop the car from continuing to be total bunk, but at least the issue at hand was solved.

(And to be clear, I actually expect the PreSonus interface to work out great -- bunk not to be implied here.)

I decided to be aggressive with the MacBook and to start from a baseline with basically *zero* extra stuff doing I/O. I did the following:
1. A *full* (offline) defrag of my drive w/iDefrag. For my 500g drive, this took 5-6 hours.
LOTS of red areas detected!
2. Disabled Dashboard.
3. Disabled Spotlight (both indexing and the icon in the menu bar).
4. Revisited hdapm. Apparently, according to system.log, there was no trace of
hpadm starting, so I rebuilt and reinstalled (chmod + perms via Cmd-I) hpadm.plist
and rebooted. hdapm was now fixed apparently.
5. Looked at new firmware for the Seagate Momentus 7200.4, but decided against it
at this time since there is no Seagate-released firmware for the drive, only an OEM
release by Dell for their PC notebooks.
6. Confirmed that I was running version 2 of the drive firmware, which was known to be
fine by most accounts I'd read.
7. Disabled drive sleep w/power adapter and not. (I never record w/battery, btw. ONLY
with power hooked up.)
8. Disabled sudden motion sensor (sudo pmset -g sms 0) because it was rumored that
vibrations or other external factors could tweak the sms so the drive would go offline
and drop outs would result. Mind you, I never observed this with the built-in audio,
but whatever.
9. Disabled all login items (iTunes Helper, AFP backup drive, Canon Scan Utiity).
10. Reboot-o-rama to get all this stuff going.
11. Told logic 9 to startup 64 bit. Why not? Probably not relevant but I figured that if
I could run 64-bit apps, why not take advantage?
12. Forgot to mention that I had already turned off all visual effects in OS X and
also use a solid background.
13. Incorrectly mentioned that I have 4g, NOT 2g of memory.

After last reboot, confirmed all things that I no longer wanted were stopped. Fired up logic, played first project where I'd noticed the drop outs 100% of the time. It played through the whole song! I set it to loop through the whole song and let it roll through 2-3 more times: no dropouts! I was able to mix down the song -- both in real time and offline -- without dropouts, pops, clicks, whatever. Played back in iTunes and it was as I had hoped.

I then did the same for all of my projects (6 in total) and the results were consistent for all. I made sure to exit logic 9 a few times (the second time through for all projects) and start from scratch, but all seems happier now and good behavior has been consistent across even projects who use higher CPU than others!

(Again, it's befuddling that I wouldn't see this with built-in audio, but I'll take it.)

After these tests, I decided to exercise the system by starting a Windows 7 VM (VirtualBox) w/1g memory allocated to it, and run the tests again. I was hoping to find the sweet spot where the system said "uh uh" and drop outs started again. Everything continued to work.

I started Firefox while the VM and logic 9 were going and tried tests again. Still fine.

Added iTunes to the mix. Still fine.

Added VNCViewer to the mix. Still fine.

Now I have to do some recording tests with the PreSonus and will update progress here once there is some to report.

Thanks again for your response and hopefully someone will find these observations useful!
