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.

iDevices are DC Coupled?

According to Sweetwater, "All Apple phones and tablets with headphone jacks are DC coupled. Check out apps like CV Mod, Brute LFO, Trigger Box, or just search for Control Voltage in the App store. "

Of course, all new iDevices are missing the headphone jack...

    So far, many of us were stuck with iOS 13.7 for lack of a no-brainer iOS 14 release.
    Now we're stuck with our older iDevices as well 😂

    Hint: Most Windows tablets can run Ableton or Bitwig quite well and they usually have headphone jacks, expandable RAM and an SSD that can be swapped by the user. It's a totally different experience from iOS though.

    I’m sure someone will correct me if incorrect, but I don’t think they are. The existence of these apps doesn’t prove that they are. For trigs and gates they’re probably ok in most cases. For modulation they may be enough (mod depth). For pitch I’m almost certain that they will fail. It’s all about the range they provide to be usable in a standardised environment (eurorack or others). You may be able to tweak it to cover an octave or two, but the point of DC coupled i/o is that you don’t have to and full range is available.

    I've just done measurements on an iPhone SE and an iPad 6, neither of them seems to have DC coupled output. There's obviously a high pass filter on the output stage, even with "measurement mode" enabled.
    Might work for triggers and modulations though...

    I remember someone on this forum being very vocal about this, saying something like "everyone already has a DC-coupled interface in their pockets". If I remember correctly, they also said that it worked with the headphone dongles. I can't find the post right now though, but maybe you'll have better luck.

    Edit:

    It looks like I was attributing all of these posts to the same person, and thought that they had provided some proof, but it's not the case:

    Brute LFO was awesome

    I’ve seen reports that the headphone output works, but needs amplification:

    I've used triggers from mirack from an iPad mini (4?) and iPad Air 3 into the clock sync of the microfreak and the SQ-1. Both work after some tweaking.

    I just tried looking, but cannot find it at the moment, but the headphone adapter also works.
