Hi:)

I've discovered that either my Luna 2 card, has a very low limit at simultaneously playback. In Logic Audio, I've used (at the time), 9 audioinstrument channels (all HALion related; samplebased instrument sounds). Even though, the first 7 channels are only simple bass, sub, cymbals and percussions:) When I load more "complex" samples like "pads" and "nylon guitar" (both from Akai samplecd's), adding eq, filtering, expander and some distortion. Well.. I don't think my Luna 2 card enjoys all the (hard?) work. Still I thought it was strong enough to handle these operations:)

What happends, is that when I record the nylon guitar together with the pads, after I've recorded the pads; the play marker (on top of the windows), starts to hoe (chattering) as if it's really pushing the limit to maximum. And then a message pops up "System (Asio) overload". It's a bit dissapointing I believe:(( But, of course; perhaps I've wired my Luna environment completely wrong.. I still have problems wiring up different modules. For example, I still haven't managed to run applications like (Sound Forge) in the background; to record (downmix) the Vsti's and the sounds from my external CS6X synthesizer. I can't just use the downmix option in Logic, since Logic can't downmix the sounds from my synth (as the sounds plays directly from my CS6X).

Thus, I can't even record simple wav -playback through Sound Forge. When I run the configuration test (Asio) in Nuendo and Logic; it's says that the communication with my audio device was lost. When I check, It's the "Luna rec 1,2 and 3", that's not configured or setup properly:) I'm sure I've done something wrong in the Luna setup. Any ideas what could be wrong? (I could take a snapshot of my Luna 2 configuration, and post it here maybe; just for ease?).

Well; I think that was about everything.. of yeah, as I remember. Concerning the Asio trouble (limit); when I work with HALion (audio instruments), in Logic. The system suddenly just "hangs". It's impossible to predict when the hanging will take place. Except the hanging always happends, when I record or play back samples via HALion. So, could the reason be related to the soundcard (Asio devices) or the HALion itself? Strangely, if the last alternative would be the fact, then Steinberg has a serious problem:) Or a serious bug! Could of course be incompatibilities with my mainboard, or any of the other hardware devices? I don't know.. Any ideas why the system suddenly "hangs" like that? That would be the most frustrating thing at this time:) Restaring my computer all the time. 5 minutes recording in Logic, system hangs, restarting the computer, entering Logic, remapping all the instruments in HALion (again! HALion never remembers any of the information), then 5 minutes of recording, and the same thing happends again.. ARGGHH!!

Well, that would be all:) A lot of problems, but I won't give up. Everything has a solution:)

Appreciate any help. Any ideas, thoughts:))

Take care now:)
Best regards,

Asio virus 2002:) Well, if only that could be the answer..:)

I must honestly admit; the Luna 2 card seems pretty okay:) But because my lack of rewiring and configuration knowledge, it's ought that things can get pretty ugly!:)

Before I bought the Luna 2 card, I was convinced that this card would be nothing more that simple "plug and play". Just plug it in, install the drivers and the software, and you're ready to party!? Not really, I knew I would front some stucks and yucks soon enough. It's part of everyday life:)

We'll learn as long as we live; perhaps creamware should press a label on their future board releases : "WARNING!!! BY INSTALLING THIS CARD, YOU MUST ACCEPT THE FACTS, THAT MAJOR FRUSTRATION AND IRRITATION MIGHT OCCUR WITHIN VERY SHORT TIME!". (just kidding.. no probs indeed:))

I must be patient, together with a few other creamware board users:)

So ,now it's back to the working and testing plattform:) Un and re -installing, testing, experimenting:) I think it's kinda fun!:)


Talk to ya later:)

Good luck! Take care;
Best regards,

I have the same problem with my Luna 2. It's happening all the time with Logic. I don't even have to play or record anything. Just switching windows can cause an Asio overload on my system. It's worse when I play something because it causes a lot of clipping.

I'm using a freshly installed and tuned Win2k, Luna2(v3 soft) and Logic 4.81. Of course, it could be caused by my Via mobo but I think it's something else. I mean, how could I have a PCI bandwidth problem when I'm not transfering anything?

Any ideas?

ASIO busses use PCI bandwidth once they're activated in a sequencer or so.

Samplers will use PCI when played.

DSP devices like Reverbs and delays use PCI whenever there's something connected to the device. A reverb that's loaded into your Pulsar project will only use PCI when there's something on its I/O's.

Well, my Luna project has 4 Asio2 sources and 24 destinations. If the Asio drivers consume bandwidth by virtue of being loaded, that could be the problem.

I'm curious though, do you know what kind of signal goes through the drivers when I'm not playing or recording anything? Sync maybe?

As I said in my previous post, it happens just by switching windows between Luna and Logic, even when I'm not playing or recording anything.

I will try to shoot here <...
-Does it happened to you Just after you open your computer?
-or 10/15 minutes after?
-Do you have many cards in your computer?
-Do you have your DSP Meter jumping on/off in pulsar?
If it so i was passing some similar problem with ASIO .

and discover that the moment the computer was working it become very 'Hot' (can be loading akai samples, or recording audio),
and the ASIO warning came up!

so,i opened the Fan to see and it was FULLLL
Of Dust,and i felt a lot of hit coming i clean good with alcohol put back the Fun back and ......

working Now like a charm .

I don't know the reason, why the hit cos that kind of software Problem.
But it works
Try it can work for you too.

The only cards installed in my computer are my Luna2, a network card and an AGP video card. I also removed all the dust I could find when I installed my Luna2(a few days ago).

I just tried to set PCI arbitration to PCI and I still have this problem. It's crazy! All I have to do is minimize and maximize the Luna window and I get an Asio overload.

I also tried to reduce my Asio i/o to 4 sources and 8 destinations and I still get this problem.

Tomorrow, I'll try switching PCI slots to see if there's any difference.

Well, strange.. I've discovered that while I'm in Logic; I don't have to do anything until the Asio overload message pops up!:( I only need to start Logic, and then holde or pause the process (without doing ANYTHING) for a few minutes. Then the Asio overload message pops up! Strange.. Not just while recording or playing back HALion (VSTi's).

I've checked my processor temperature, and it stays 55 degrees. When the CPU process different and major calculations, it pops up to around 60 degress. However, this should not have any impact on the ASIO problems. Or sound card in general. AMD Athlon processors, should handle temperatures between 50-65 degrees just fine. As I've read this in several discussion forums. But that's the AMD. Still, I can't figure out why I get the overload messages. I haven't hosted the dsp's or loaded any information that nearly doesn't use any dsp at all.. Like you mentioned, it's worth a try to swap PCI bus. And maybe that helps.. I've tried many things; changing the PCI IRQ mapping in BIOS, I/O adresses PCI latencies; removed different memory adresses to other available locations (within Win98), but it's not helping very much.. so position the card in another PCI.. Hope this might help..

Perhaps it's due to incompatibilities with the mainboard, mem modules, or something?? Maybe I should buy another mainboard (the Creamware Luna 2 would get far more expensive in that case:))..

Well, We'll keep each other informed:) Try to figure out this ASIO probs out.. We'll talk:) Thanks for the posts:) "Nice" to know, that we possibly share the same prob.. (kinda:)).

Best regards; respect

If you are using Win2k or XP with Pulsar and Logic :

Set priority in task manager for Logic to "AboveNormal" (it is "Normal" by default). Leave Pulsar at its default setting (Normal).

This will cure your ASIO overload problems.

There is also a way to set up a shortcut to Logic so that it starts up every time with this setting. Someone else will have to post that though as I can't remember exactly what it is right now.

Yeah that one looks cool, but actually you don't need a separate app... you can use the "Run" command, already built into WinXP/2k.

Also that app doesn't seem to have the correct range of CPU priority labels. It might be only for a multi-processor kernel (I haven't used that kernel, only the Standard PC one, so I can't be sure).

Yes, setting Logic and Luna to realtime gets rid of the problem. I had this tip this afternoon from a friend at work that uses Cubase and has the same problems.

Thanks!

BTW, does anyone that is on a different platform than Win2k has the same problem?

I went over to E-magic's own internal software -sampler solution instead. The EXS24. Even though; it's slightly different from HALion. The system doesn't seem to hang at least, thus the overload probs. are still in the air:(( I didn't quite figure out how you solved your ASIO overload difficulties. Did you change the priority setting for Logic and the Pular project?

Well; How exactly do I change the priority setting for Logic in the taskmanager?
(I'm not that familiar with Logic.. or the taskmanager:))

Appreciate all the great help this far:) Hope for some more advice and tips:)

Btw; my setup at the moment. All the different modules (ASIO 2, EASI and Wave sources) runs through the recording mixer (AUX L&R 1,2 and 3 (4 available)). Differently I've connected the Luna Analog source L&R, through the rec mixer's In01 and In02. Then, all the different module connections via the rec mixer's Out L and Out R; assigned to their respective module destinations:) Concerning the Midi connection (don't know if this has anything to do with this prob);

Sequencer Midi Source => Rec mixer Midi In and (the second wire from the Seq Midi Source) => Luna Midi destination.

Then Luna Midi Source => Midi merger (is this nescessary?) MIn1 => Mout => Seq Midi dest1.

And the Midi out (from the rec mixer) => Midi merger MIn2 => Mout => Seq Midi dest1.

Pheww; confusing.. I just tried to describe the routings I've made in the Luna 2 environment.

I currently run Win98 (sec edition), on my HD1; thus WinXP on my HD2. Win98's the primary OS. Else, I've only got my Nvidia Geforce 2 MX64, and my ethernet card;

<AMD Athlon 1,4; Asus A7A266 MB; 512mb DDR>

That would be my configuration at the moment. I guess I've connected the modules within my Luna 2 project all wrong.. I just had to try and try.. It's not that easy:)

Well then, gotta get some sleep now.

Take care; Best regards,

To change Logic and Luna's priority, go in the Task Manager's Process tab. There, right click on the Luna.exe process and under "set priority", select "realtime".

Repeat for the Logic process or wathever other sequencer you use.

Note that, with Cubase, this sometimes causes Windows to hang.

FWIW, these problems are related to 1. Win2k/XP and 2. Dual CPU and priority/cpu affinity settings and 3. Via chipsets.

Best bet: Win98SE/ME, Intel chipsets. But I guess that's not the advice you wanted to hear. :smile:

Well...

1. Win2k/XP: I have to be able to read and write to NTFS because I often need to swap a data HD with anoter Win2k system. Not many options there. :roll:

2. Dual CPU: I only have 1! :smile:

3. Via chipset: Buying my Luna wasn't quite expected in my budget so, I'll have to wait a few months before switching motherboard. :sad:


Hey!, it's not a perfect world(yet)... :smile:

You cannot use EASI and ASIO drivers in the same project. In fact, don't use EASI drivers at all...

Regarding the rest of this thread:
The combination of Logic and Pulsar in Windows2000/XP still has major problems which can't be solved by any amount of tweaks'n'tricks. Asio overloads are just one small part of that equation...
