Class-compliant mode (USB Audio/MIDI in USB CFG) presents the DT as a 2x2 audio interface on the computer, but its inputs will only work in Overbridge mode (shows as 12x2 interface).
Although it’s not a bug, it’s bad form to show the 2x inputs if they can’t actually be used. Maybe things will improve here but the DT is a mature product now, so who knows…
The 2x inputs are there to record the output of the DT. How would you record the sequences to iPad or computer otherwise?. It’s not just for Overbridge. iPad has no overbridge but you can use the DT as audio interface (thus class compliant).
What’s missing is output from the DT jack/external inputs when used as audio interface. No way to get external jack input on iPad, which prevents it from being a usable audio interface.
i was replying to giacecco about the physical inputs on the DT
Hi. yeah, I was trying to say that the 2x inputs in interface mode do work, but they are for the DT output (stereo out of sequences). So it’s not “bad form” to display them. Without them you wouldn’t be able to do anything, like record the output of a DT song.
To be able to use the physical inputs they should (ideally) be on a outputs 3&4. That’s what’s missing.
Cheers!
are you confusing inputs and outputs here? i don’t understand what you mean
Audio interface shows 2 inputs and 2 outputs from DT.
In your daw you choose DT inputs 1 & 2 to record sound from DT to your daw (iPad or computer).
In your daw you choose DT as output to listen to audio.
There’s no way to record audio from jacks plugged into DT (guitar, etc),
It’s confusing cos inputs in the DAW (iPad) are outputs in DT, it’s messy to explain. Sorry if I wasn’t clear.
Actually there is.
In Logic I create an Overbridge instrument track to record MIDI notes from the Digitakt(although i really don’t usually)
To record the main outputs of the Digitakt I use an audio track with inputs 1-2.
To record my stereo external synth which is sequenced by the Digitakt via MIDI I use an audio track using inputs 11-12.
You have to set it in monitoring mode in order to hear it and make it record enabled.
this whole thread is about class compliant mode, not overbridge mode.
Exactly, there’s no overbridge for iPad.
Haven’t tried this as with my Mac I already have an interface to record. But it brings up the question. If you can record external inputs via Overbridge… It can’t be a hardware limitation. Right?. That’s been my point all along. I can’t see why it can’t be done. Obviously there must be a catch somewhere. It would really bump up the usability with ipad. Like night and day.
As I said if you need to switch interface for recording it’s pretty pointless. Furthermore the DT is usually the first instrument, the base, rhythm track . You’re probably gonna a bass, synth or guitar after the DT. To do that you have to ‘unplug’ the DT… No rhythm track. Gotcha. So you need to bounce it to audio, might as well plug it as audio into the interface with actual audio in the first place. See my point?.
I think that’s probably correct.
Most audio interfaces I own(that have a Class Compliant mode) expose all their channels to the system regardless which driver is being used(i.e. RME, Denon, iConnectivity, Allen & Heath).
The only limitation I know of is USB Audio Class 1.1, which is limited to 2 channels input and output.
And nobody has used that for years.
Not a bug, it’s intentional for reasons nobody in this threads can explain.
Yep it makes no sense actually.Class compliant means that it can interface itself.Also stereo monitoring would be a huge thing on standalone and seems weird that only Overbridge can enable it.
I have an external sound card as well but I ditched it because on vacation where I took just the Digitakt and the Mac mini with me and it worked like a charm as a soundcard,so less gear hassle too.But I didn’t use external inputs there.
What I was almost never able to achieve was the iPad configuration…
Ipad always says that “the device requires too much power” and even if I plug the power afterwards,it makes no difference.It only worked once or twice before the update,where I was able to sequence the Animoog.And only via powered usb hub.Could also be that my cck cable is probably shit.But I read here in some post that a USB B to lightning could work too since the device is class compliant.I will try this one next.
You might have more luck with a powered usb hub, so u go digitakt -> hub -> ipad where the hub has its own wall wart power. I havent tried it with a digitakt but its worked for me with other stuff.
It worked like 2-3 times pre update with a powered usb hub but it does not work anymore.Though it’s possibly my cck that was used when I got it and I guess it was a kinda faulty one.Then again it shouldn’t work at all I guess…Really messed with my brain this adapter.Idk,did people here always had a stable connection using it,or it’s a common issue?
I also read here somewhere that people had luck with a usb B to lightning but I don’t exactly remember if it was for usb MIDI only.
I guess I will have to try that too and I will report results when I do.
Yeah, those things can be crazy sensitive.
In my experience, all connectors and cables must be in optimum state and of decent quality. If one of those is off by even a little bit, stuff doesn’t connect or generates error messages.
I don’t think these exist officially. Most 3rd party cables that are not authorised by Apple stop working at some point when an update comes along.
But if you find a working one, please post it here. I hate Apple’s flimsy CCK.
Officially from Apple it certainly doesn’t exist.
It’s an amazon product which is advertised as a midi adapter.Im interested in how it works,although it kinda kills my Overbridge setup.It seems better than the lousy cck and the whole usb hub story though.
Nonetheless I would like to try it.Will let you know what it does if I get it 
I recommend the original Apple CCK. I used the Digitakt connected this way a lot without any problems.
Never had a problem with Apple CCk and the DT, skipped that problem and moved ahead to make my life miserable with the lack of audio inserts in usb.
This is pretty much what I thought of (and requested as a feature long ago)
Even if it disables sampling, having a “live” mode which only works for stereo monitoring would make a huge difference.
Why did elektron do this…
Is the Digitakt being kneecapped to move people on to bigger elektron boxes?
Still no bandpass filter (I have to externally process samples on other samplers then bring them back in to DT just to apply a BP filter)
And now I discover that the inputs don’t work on class compliant mode…
I love the DT and it’s sad
