iOS multiple usb input possible?

The Lounge Other Gear

I finally bought the camera adapter for my iPhone so I can connect it to my Digitakt.

Does anyone know if it’s possible to connect more gear to your iPhone using an USB hub?

I was thinking about using my iPhone as a looper to record guitar. But I want the audio going back through my DT. If I use the DT as an interface, the loop app will also record the DT tracks. So I was thinking about also hooking an audio interface to the iPhone and then use Audiobus or AUM to route the input to the loop app and the output to my Digitakt.

Or am I asking to much of a phone?

You can only connect one USB audio interface at a time. If you use a regular USB hub, though, you can also connect as many USB midi devices as you like.

Edit: you can do a lot of creative routing with AUM etc, especially if your audio interface has multiple ins and out.

Thanks. So the DT will still work with a hub?

I am starting to like my phone. Sure the screen is small, but you get used to it.

Yes, it should do.

Do you mean that I can plug for example a digitakt, digitone and tr-6s in a USB hub and I can have 3 separate audio/midi streams on the iPad?

You can have as many midi interfaces as you want, but iOS only allows 1 audio interface. The last one connected wins. Everything has to be class compliant.

Ok that’s what I thought. Midi is fine but audio is down to one because a USB hub is not an audio interface

It can be. You can plug an interface into a hub. Some hubs have headphone jacks. You can plug everything into 1 hub.

If you’re planning to use Overbridge then it can be quite picky about USB hubs from what I understand - Elektron even make their own.

Can’t remember the specifics but you’ll want to make sure you get the right kind, and I think it needs to be powered.

Doesn’t have to be powered if you connect devices that have their own power (i.e. all Elektron devices).

They recommend that you power the USB hub if you are going to connect things like external hard drives that draw their power from USB.

Is this right?
So the last device you physically connect wins the iOS audio output? Or the last in the physical line of USB devices? (Time vs position)

I think it was that it needed to be ‘Multi TT’ compatible, or ‘MTT’ - but yea that’s probably what I was thinking of - that if there are other devices drawing power it will cause you problems.

Edit: Correction, this is only important when using various Elektron boxes, some of which are USB 1.0

Correct, it requires (or at least recommended, not sure) MTT.

The Elektron hub doesn’t come with a PSU, so if you need that you have to source it yourself. (They have the specs in the manual or on the website)

This one.
