Hi,

I have a question on Reaper in combination with multiple ASIO drivers.

The problem I am having is that I want to use one ASIO driver for playback of my tracks while using another ASIO driver for recording.

I have a built-in Audio card in my PC (WinXP/SP3) that has a nice (quick!) ASIO driver. This is the one I use for playback. It outputs to my mixing console and speakers (4 inputs/8 outputs).

I have a Roland VG-99 digital guitar modeler that connects via USB to my PC and also is represented by an ASIO driver. I use USB to skip a DA/AD conversion stage.

When I want to record the digital guitar in Reaper but play back the song's tracks through my main audio card.

Problem is that I can only select one ASIO in Reaper and not split up which one I want to use for playback (output) and which one for recording (input).

Hope it makes sense.
Thanx!

I too would like to be able to do this...

The restriction to one ASIO device at a time is part of the ASIO specification.

It's not Reaper's problem that Windows don't support multiple ASIO drivers working simultaneously. You will not make it work with any DAW, for that matter. That's just a no-go. Maybe you could make it work with 2 DAWs, but I don't think it would work properly, and that wouldn't be so useful anyway, huh?

ASIO is very greedy, selfish driver. So many things can influence its performance... like antivirus programs, wireless LAN drivers, other drivers that are too greedy on the resources...

Some ASIO drivers can't even work with multiple applications at the same time. So called "non multiclient ASIO driver". M-audio Delta springs to mind. That can be a problem to set up properly when you want to use an external audio editor with the ASIO driver that your DAW uses at the same time.

You can maybe make use of Reaper's ReaRoute ASIO driver, though, somehow. I'm too tired to think about it now, but investigate ReaRoute ASIO... Reaper can use ReaRoute and your normal ASIO driver simultaneously.

I hope I helped at least a bit.

I read somewhere that using WDM drivers for multiple devices and ASIO4ALL you can make one ASIO device from that.

I'm not sure if I got it right though.

If using vendor like RME that support multiple devices of their own line of products - they handle sync between these.

Best way would be to just use audio from VG-99 instead - unless the ASIO4ALL mentioned works.

I forgot to mention that any ADDA conversion should be better than the one over USB. USB converters are the worst quality ADDA converters you can get at any price. Absolute bottom. I would always rather use digital out, or line out, and normal MIDI jacks for sending/receiving MIDI. MIDI timing over normal MIDI jacks is always better, especially if you're using a PCI/PCIe internal audio card!

USB is for flash drives and printers. No matter 1.0, 2.0, 3.0... it's all the same $hit.

Or use USB only when you really cannot use any other option. It's jittery as hell, not really good at streaming data reliably and consistently.

So what my suggestion is: forget about the USB and connect the VG-99 properly with your internal PC card. Less problems + better timing + better quality = proper connection!

cons: more cables.

Cheers!

If I remember right, Asio4all can definitely do this, that was a trick used to use 2 soundcards to have two different simultaneous outputs while your soundcards has only 1 output each (like an old soundblaster and an integrated soundcard for example).

Yes! I've got it working with ASIO4ALL v2.

You have to open up the ASIO4ALL driver properties where you can select the devices that have to show up.

Thanx!

Really?? I wonder what this is then:

The USB technology / protocol is not the problem, lazy manufacturers that provide shitty drivers though are.

BTW: it is not working after all.

I can see all devices in Reaper when I select ASIO4ALL (and go into details to select these devices). But As soon as I select the VG-99 driver, Reaper does not play the song anymore (no song pointer/no counters running- nothing). When I deselect the VG-99 driver from ASIO4ALL it works again.

Stumped...

But I don't think you should select VG99 driver in Reaper when this is going through ASIO4ALL.

It makes more sense to select ASIO4ALL to me - since this is collecting the others.

Or maybe I read you wrong?

Yeah, I select the ASIO4ALL driver in Reaper.
But in the details dialog for ASIO4ALL you can select the devices it has found.

But I have tried both and neither works.

Still stumped...

Have a shot or a dozen, a big pizza, and google.
