Multiple Asio Apps

Jon_Slaughter · Jan 10, 2008, 09:13 AM

How can you run multiple asio apps at the same time? When I run two I end up with the second one having an error about the buffer size being to large and to many channels. I just switched to kx after using creative's asio for a long time. I did not have any issues running multiple asio apps with creative. I also don't remember having that problem a few years ago when I used kx.

Is this something new with kx or is it a setup problem?

While I never tried...
try this..
In APP1 - only assign/enable ASIO channels 0-7
in APP2 - only assign/enable ASIO channels 8-15

The point, is don't enable all ASIO channels in both apps, what ever is enabled in one app, dis-able in the other app.

Also, try enabling 'Driver Compatibility - SMT/HT Optimizations' in kX settings - maybe that will have some affect. (??)

Another thing I notice, in Sonar - there is an option 'Share device Driver with other programs' - but.. when enabled, simply allows 'sharing' when sonar is not in focus..
So, I can't imagine how that would work.

Maybe that would work?? Sorry thats all I can think of, if it is at all possible, this maybe is how.

Are you sure you didn't use a 'VST' version of what ever second application you are remembering (Guitar Rig and Cubase for instance, guitar rig has a VST and stand alone application - or Sonar and Reason - using REWIRE not VST.. ??)
- because I didn't think sharing is possible (other than *possibly* my first suggestion, of making sure Individual ASIO Channels are not enabled in both apps at same time)

WDM drive model maybe - as I believe they are 'multi-client' in nature. But I would be surprised if ASIO is 'multi-client', from the option found in Sonar I mentioned alone, makes me think this is not otherwise possible.

Not sure what you are talking about. The apps don't let you select the channels. (You just tell it which asio channel you want for input and which one for output)

No, these were not VST's. I used nuendo and audition 2 and 3 side by side. I've used reason and Guitar rig side by side. Even EW QL Symphonic orchestra with audition side by side(but opening up So first then auditions and not using it as a VST inside audition).

There is not SMT/HT setting in kx. I'm not using a dual core or HT.

The error I get is

"
Error creating input buffer #0: error -2147024809[size=4096]
GetLastError()=2

E_INVALIDARG: Too big latency and too many channels - resetting latency...

Retry()
"

I am pretty sure that one can run multiple asio apps at the same time. I also don't ever remember having this problem when I first started using kx a few years ago.
