Audiobus: Use your music apps together.

What is Audiobus?Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Loopy Pro - Routing audio to an Audio Unit input track (Koala Sampler)

I’m hoping that a Loopy Pro and Koala Sampler enthusiast can assist me with something.

Working only within Loopy Pro, I’d like to send my remarkably poor live guitar playing audio (processed with effects) to Koala Sampler. I’d like to sample that audio and then use Koala Sampler to generate sequences with chopped samples without loading/unloading Audio Units across different tracks.

My explorations have led me to understand that:

  • Creating an Audio Unit input track gives me an instance of Koala Sampler that’s fully functional - aside from not being able to sample live audio. I assume this is because Koala Sampler is the top-level input of the channel and nothing can be inserted before it.
  • Inserting Koala Sampler as an Audio Unit effect allows it to receive audio either from the channel’s top-level input or from audio routed to the channel. It can sample all kinds of processed audio this way. However, I can’t hear Koala Sampler’s output in this configuration.

I also get that:

  • I could use Koala Sampler as an insert effect, receive audio, save a sampler preset with that audio, delete the sampler instance, reload the sampler as an Audio Unit input and then reload the sampler preset. However, that’s gross.
  • I could use AUM (and have done so) to make this all work in a roundabout way. That’s fun, but I’d like to do all of this inside Loopy Pro without changing track configurations repeatedly.

I have mostly RTFM and tried to work this out my own. If the solution is something obvious that I’ve missed, I apologize to my peers. You’re all appreciated regardless.

    You should be able to hear Koala's output just fine. I'm not sure if you're referring to the output when you're sampling something, or output from the pads and sequencer. If when sampling, Is monitoring (headphone icon) enabled? If from the pads and sequencer, make sure that the plugin doesn't show "idle" at the top-right. If it does, then long-press idle and turn off "Enable Idle Mode".

    Failing that, maybe post a screenshot of your setup, showing the Koala FX plugin window and the Loopy mixer if possible.

  • Thanks for this response. I appreciate it. I double-checked that the plugin wasn't idle, but your suggestion got me thinking about other possible solutions.

    In the end, I got this to work by inserting Koala Sampler into a hardware input channel and ensuring that monitoring was enabled. I thought this only applied to the input source and not all subsequent plugins in the channel. Once I enabled that, I was able to hear Koala Sampler's output.

    This led to the discovery that I could also monitor the input channel through another channel/color, and that also works for my application.

    i usually create a bus and put Koala as an effect on it. that way koala can get input from anywhere and send its output to any color. And make sure to turn off Enable Idle for the koala instance.

  • Great suggestion. I will experiment with this as well.

  • I had this problem during the beta phase. Like @espiegel123 says, turning off idle mode works.
