AUM & Audiobus limits Output choices in Loopy Pro

I'm a guitarist (read into that what you may). I would like to do something that seems quite simple but is proving to be challenging in Loopy Pro: Guitar - Behringer UMC404HD - Bias Effects Guitar App - Loopy Pro with the outputs on the Behringer ending up as follows: Out 1 - Click Only, Out 2- Unused, Out 3 & 4 - stereo out that includes the Bias Effect processed Gtr and all loops from Loopy Pro WITHOUT THE CLICK. For the life of me, I cannot figure out how to do this. Every time I try to insert Loopy Pro into an AUM or Audiobus chain, the possible output options are reduced to two (instead of four which I see when using Loopy Pro standalone). I realize looking at some of the crazy stuff being done that this may be a really rudimentary question, but I have really searched and can't find a solution for such. Any push in the right direction would be greatly appreciated.


  • Hey @mcriscione - yes, currently LP doesn’t expose more than one stereo output when it’s used as an audio unit. I’ll be doing two things shortly: adding multichannel output as an audio unit, and also adding support for IAA in the standalone version so you’ll be able to use Bias from there

  • Hi support for IAA will be FANTASTIC! Thanks can’t wait…

  • Thank you so Michael! I’m so excited at all the possibilities this will open up. Congratulations on the release of this groundbreaking masterpiece. Well, well worth the wait!!!

    With that one sentence you just saved me $120, because I was about to buy Overloud TH-U just to be able to load a guitar AU into Loopy Pro. Thank you!

  • Whoa! It’s $120?! I am undercharging 😄

  • And thank you guys!

    YOU are wondercharging! But yes, Loopy pro is absolute GOLD <3
    Also, that TH-U price is for a complete bundle, its their (amazing) amp and distortion models that cost the most.

  • 😄

    Ah, fair enough! I mean, fair enough either way really.

  • We have IAA now, but only for inputting into LP, right? I can't set it up so I can route multiple IAA channels out of LP and into AUM!?

  • Nope. But multi in/out for the AUv3 is on the roadmap (https://roadmap.loopypro.com/loopy-pro?card=6232868b82e991002a92f8f8)

  • That's definitely cool, but my problem is that I'm using AUs in Loopy and when using Loopy as AU these don't load. I would then need to drag them out of Loopy and put them in a channel in AUM but then I can't control parameters with widgets and it also breaks different setups with different projects.
    Any chance IAA outputs will come at some point?
    Or a mixer inside Loopy that is static and will not change when loading projects?

  • ...or input/output buses that live outside projects on kind of a master app level?

  • Any updates on multi out? I'd love to have more routing flexibility in AUM!
