Is it possible to use 2 the same soundcards in the same computer? I was thinking about getting the ESI Juli@ soundcard and use nr. 1 for example for Breakaway Live (low latency with asio). And to use the second for Breakaway Broadcast also via asio. I’ve heard something about these card that you can’t use asio 2 times for 2 the same cards.
You heard correct. If you have two ESI Juli@ cards, or two M Audio AP192 cards, once you open the asio driver, both cards will be opened whether you like it or not.
Thus, you cannot open one card at 48 kHz ASIO and expect to open the other at 192 kernel streaming.
You could if you buy one of each though (that is, one ESI Juli@ and one AP192).
However, at this point, I would recommend that you wait a couple of weeks for the beta of BBP ASIO. That one will be able to do everything through a single ASIO driver. Thus, for example, you’ll be able to have the following configuration:
Card 1 L/R Input = Audio Input
Card 1 L/R Output = Low-latency studio output (under 10ms latency)
Card 2 L Input = RDS/Sync input (optional)
Card 2 L Output = MPX output (18ms low latency OR full quality)You’ll also be able to use a single card in the following configuration:
L/R Input = Audio Input
L Output = MPX output (18ms low latency OR full quality)
R Output = Mono Studio Output (under 10ms latency)Best regards,
///LeifLeif,
Out of interest I went down to talk to one of the techs in our recording studios as I know they have machines that have multiple soundcards of the same type and brand in the one machine. Many times I’ve used one that has 2 RME RayDAT cards running ASIO at 2 x 64 buffers. Beautiful cards, about 3ms latency. The techo tells me they could run it at 1 x 32 buffers but if Windows hiccups then it’s a retake.
Back to the topic, he tells me some ASIO Drivers are multiclient and some are not. Depends on the manufacturer. Seems even some of RMEs are multiclient and some not. These people just like to confuse our lives. 🙂
I notice with our Audioscience cards they have jumpers for the ID of the card when you have more than one of them in the same machine. I think they share the same driver. Maybe it makes one of them provide Master Word Clock to the other too.

Hi Scotty!
Indeed, they don’t make it easy.
Also, as far as I understand it, "multiclient" means:
Multiple applications can open the same ASIO driver, and each of these asio drivers will open all the available cards in the computer.
As far as I know, it never means:
With multiple cards, multiple applications can open a driver each and get full control over the card they opened.
Architecture wise, I understand why it works this way — for most applications, it’s a really nice thing that you get to use multiple cards in sync on the same asio driver! It’s just a matter of conforming to this scenario, and BBP ASIO, which is (as the name implies) designed to work with ASIO drivers, will indeed conform. 🙂
Best,
///LeifLeif,
Thanks for clarifying that. I misunderstood what was the "client" to the driver.
No wonder the techs around this place say the air staff know just enough to be dangerous. 🙂
Just to confuse me more 🙂 can Plpelines (VAC in my case) drop buffers in normal use? I had quite a bit of it today when I was showing BBP to one of our interstate station guys. I was getting it about every few songs, no regular pattern, but it was noticeable.
Scott
It’s not suppose to be able to drop buffers, but it does seem like it is. I’ve had some problems myself with the pipeline on quad core systems. I’m currently testing a bug fixed version, which I will include in future versions if I don’t find any problems.
Best,
///LeifLeif,
I look forward to the results of your work on the updated version of Pipeline.
I did some tests today running AES into a machine with BBP and then AES out to the switcher for the studio monitoring and no buffer drops for the time it was running, so I would say VAC was dropping buffers yesterday. I wonder if the buffer drops were related to the fact that I set VAC to 1ms per Int some time ago. I am sure I had noticed dropped buffers before then which made me think of aligning the settings to Pipeline’s setting of 1ms per Int.
In real world operation for us the pipelines or VAC wouldn’t be used anyway. Just helps when I’m showing it around.

I am currently using 2 Juli@ cards, all I need is 4 mono inputs (and outputs) with low latency. We need 4 analog ins and outs for a signal processing app. Looks like I can get 1 channel of one card and the other channel on the second card. Have not found any docs on the breakaway pipeline config, not sure what all the settings refer to " cable, NC, etc." Any clues here? If both cards are opened w/ the ASIO driver, not sure why I can only get one analog channel on each card?
thanks!Hi Jon!
If you run Breakaway Live in ASIO mode, you should be able to select exactly the channels you want to use.

Hi, Leif, Jesse, George, et. al.,
I've been scouring a number of threads looking for what I might be missing. I have seen threads that say you cannot use two sound cards, and this one implies you can. I am trying to use BBP ASIO in a streaming box configured like so:
-Studio Analog L/R in through M-Audio Delta AP192
-M-Audio Wave Out to Vendor's Spot Substitution Software
-Software Wave out to EMU 0404PCI Wave IN
-EMU 0404 Physical Analog L/R Outputs to Watermarking Hardware
-Watermarking Hardware back into EMU through Physical L/R
-Send to ASIO for BBP L/R In
-BBP L/R FM out through ASIO back into EMU
-EMU final mix Send Wave to Vendor encoding package (Or for offline test, Windows Media Encoder)All at 48k except the initial input to the M-Audio is 44.1.
I followed George's EMU 0404 set up instructions at http://www.forumclaessonedwards.com/forum/index.php/topic,2145.msg11217.html#msg11217 and things seemed to be falling into place. I set up BBP I/O to ASIO channels.
However, once I reopened the the PatchMix for the EMU strange things happened. The I/O setup for BBP, with EMU selected, would indicate everything from 'Invalid' to 'PCI Card In L A' on the left input and the same for right. The menu selections were limited on both in and out. The Output does indicate the ASIO channels for the left and the right (ASIO OUT 31/32 A). The interesting thing is that BBP is receiving audio from the EMU, but there is no real return. I do see some noise indicated on the Peak Meter inserted on the EMU channel strip. If using the BBP I/O setup and turning the test tone on and off, I see the noise come and go.
I saw the ASIO4All thread- would that help, or just add to the confusion?
Regular BBP does work reasonably well when placed completely after the EMU and before the encoder, except at times both versions will grab the EMU physical input and the audio is not returned. Have not dug enough on that to see a pattern yet.
Thoughts, comments, suggestions?
thanksKS
Multiple soundcards showing up in ASIO is a function of the soundcard drivers, so that only works for multiples of the same soundcard.
ASIO4All is just a fake ASIO driver that interfaces with the soundcard/s using Kernel Streaming, so it's only a disadvantage (more links to break, and more buffer) to just using Kernel Streaming instead.
