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.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Easiest setup to loop both guitar and mic separately (to old iPad 2)?
I'm currently busking on the streets of Newzealand with an acoustic guitar (Yamaha APXT2 travel guitar, https://usa.yamaha.com/products/musical_instruments/guitars_basses/ac_guitars/apx-t/index.html) and a mic, both connected to a small portable amp (Roland Street Cube, https://www.roland.com/global/products/cube_street/). I'm pretty new to looping, but I want to use it for future busking. I played around with Group The Loop (which luckily is working on my ooold iPad 2) for live looping, and it looks very promising to me.
My only problem is, that I can only use either my guitar or my mic for looping, as I can hook up only one of them to the mic input of the iPad (using an iRig 2, https://www.ikmultimedia.com/products/irig2/). I hoped that the iPad's input would be stereo so I could route the guitar to the left channel, and the mic to the right channel; but apparently iDevices generally only offer mono input through.
This is a bummer, as I'd really love to record and loop both mic and guitar in the same song, so I can build up complex loops, like strumming and a separate bassline using my guitar, and singing in harmony or doing beatboxing through the mic. At the time being, I have to decide for each song whether I want to loop guitar parts, or mic parts.
I asked at the Group The Loop forums how to solve this, and I was told to ask here, as it is unclear whether there is any external portable mixer which supports my iPad 2? I've taken a look at the Roland Go Mixer (https://www.roland.com/global/products/gomixer/) but it seems to be working only with lightning, not with a 30 pin dock connector.
So: do you know of any easy way to get a stereo signal into an iPad 2? Otherwise I will have to think about replacing it with a slightly newer iOS device...
Thank you for any hint. All the best.
