iOS looper - Audiobus, AUM, Loopy, Blueboard: how to use them (with Audiobus preset)
Lot of looper talk on our forum lately.
@McDtracy asks me for an AB preset to help him starting with Loopy stuff. So I thought it could be useful to share some of my app setup with whole AB forum community.
So here is a small explanation/tutorial of how to use Audiobus/AUM/Loopy and a pedalboard like BlueBoard.
This setup is adapted to play backing loops in Loopy and recording loops at the same time. AUM will allow for lower monitoring latency, advanced mixing, performance recording. Audiobus will glue everything, offer apps state saving and switching. Three apps have midi learn support.
Any variant is possible.
All apps routings are made in Audiobus for best sync between Loopy and AUM.
AUM goes to Loopy for loop recording
Loopy slots 1-5 goes to AUM, those slots are for imported backing loops: drum, bass, etc. A variant is to have an AB/AUM lane for each slot, but it’s more cpu intensive.
Loopy slot 6 goes to individual AUM channel, this is the audio looper slot.
Now AUM side. First channel is mic audio input. Than can be any app. Here is why it’s so interesting to use AUM: audio monitoring channel goes to AUM’s audio physical output. There is NO cumulative latency between apps, like with AB + Loopy. There is a bus A send (parallel) to Loopy input channel. Use insert effects before bus A send if you want them to be recorded in Loopy.
Here is Loopy input send, from Bus A. You can of course have various Bus A sends and trigger them by midi or on screen, for several sources Loopy recording. Signal is routed to AB then Loopy.
This is Loopy looper slot 6 return (routed though Audiobus). As you can see there is an AUM Mid/Side node which is another trick. This helps to leave some space in the stereo field if you want to soloing along your loops. This is especially useful with overdubs.
Next channel is for backing Loopy loops 1-5. You can adjust level quickly, add EQ and compression here.
At the end, master channel receive Bus B. All channels are routed to this bus except Loopy input send. Enable master channel record button and you will be able to record your whole performance as a stereo file.
And now Loopy setup. Be sure monitoring option in Loopy is disabled, as monitoring is made in AUM.
Here is track management page setup. Note that fade in/out on the upper part is enabled. This allows to do fading with a double tap :-) Synchronisation settings must be like on the screenshot if you want a synced looper behavior with count in/out, very Ableton-like. You can experiment with this.
And now let’s talk about hands freedom!! Here’s a typical BlueBoard midi actions setup. You have single and hold taps (and you can double a single/hold tap for fade in/out for any mute action) for loops slots 1 to 5. So you can basically toggle mute (play/stop synced with loops lenght). This is like playing with Launchpad or Ableton with your foot using buttons 1-2 single/hold taps and 3 single tap. Single tap button 4 will start blank recording in loop 6. Tap again to overdub. Hold button 4 to re-record, this will erase previous recordings. Button 3 hold tap will mute your loop 6 recording. Re-record will works with loop 6 playing or muted. So all muting actions are on buttons 1-3 and all recording actions on button 4.
And now the Audiobus preset:

And AUM file:
You can do lot of variants, with multiple looper slots, various sources, etc... You get the idea with routings though Audiobus, AUM busses, and loopy actions.
Edit: and of course, a little bit of shameless self-promotion. Here is what can be done with that kind of setup:
