Multiple Audio agents?

Eigenharp: Technical Help 1 Minute

Multiple Audio agents? 

Ok, silly question of the day 🙂

Id like to take an input from an audio interface, and send it to macs audio output (on audio 1) – but cannot do it!?

 I thought the way to do this, would be to create a new audio agent (audio 2) ,  and then link it to the audio interface, and takes its inputs and then feed them into the mixer, which would then outputs to audio 1, which outputs to mac.

but workbench, doesn’t allow me to create a second audio agent.

(we dont have source for audio agent, so I cannot check to see whats going on!)

Obviously I cannot change audio 1, to the audio interface, because if I do then the output is to that audio interface.

I probably can workaround using Jack OSX, DAWs etc, but Im seeing how far I can get with just EigenD… as I like to minimise the apps in use… and I like pushing EigenD :o)

side note:

I wondered how the alpha did this with the mic, but it looks like the alpha hardware exposes this directly, rather than thru an audio interface.

  1. Apparently you can only have one interface. However, you can make an aggregate device: http://support.apple.com/kb/ht3956 which contains both and then use that.

    I know I’m not technical but the ide above sound to me like:

    a) you can’t do that

    b) do it this way

    Whatever the SW does to make an aggregate device should also be possible within eigenD although that would seem to be just extra effort to include something you can do another way.

    Because I find aggregate devices clumsy, I just use my MOTU by itself. I loop the ADATs optically so whatever I send out to one ends up being an in at the other and I can route / mix it as I see fit. 2 ADATs=16 channels

  3. Tried that… unfortunately, no can do.

    The audio interface is show as an audio device, but for reason cannot be included in the aggregate devices.

    (note: i can select in EigenD, so not quite sure why its not allowed in aggregate)

  4. You can’t have multiple audio interfaces in the same application due to clocking differences, otherwise you have to start converting sample rates etc. Which is exactly what the aggregate studio device uses, so just use that.

  5. Mark Harris So the loopback would be a choice. Even if you only have SPDIF, that is still a stereo pair.

    António Machado You can add all the channels you like but not a second agent. I think Geert said this was a clocking issue? Oh, and yes, you need to remember that outs ar in and ins are out hehehe

  6. thxs, at least i know im not going mad… good to know about the clocking rates etc, that makes sense.

    aggregate: just seems to be a bit of a limitation on my audio interface software – no big issue, lots of other ways … i perhaps should be using it as output anyway.

    (the only reason im not, is I havent bought any monitors yet, only have headphone output :))

    k, I tried to use Jack OSX, but for some reason this appears broken on my new mac… basically, you cannot select JackOSX as a device in EigenD.

    im guessing this must be a mac 10.8.3 issues, as it works fine on my others macs.

    (also the jack osx VST doesnt appear to work with the AU agent)

  7. ok, no issue –  ive found another way of achieving what I was after,

    and still all in EigenD with no extra software 🙂

    (have to say Live works well for testing ideas out, and then usually you can transfer the concept to EigenD :))

  9. Thxs guys, I’d seen stuff about aggregates but they don’t work for me.

    I may buy a audio interface at some point but fortunately it looks like I can pretty much so all I need at the moment 🙂

    My only limitation is the AU agent not accepting input on multiple midi channels 🙂
