@zamal.wav: @Kpucskimight be right about this. I’m using Logic Pro 10.5.1 still, I haven’t upgraded to 10.6 yet. Are you on 10.6?
I’ve had a look at your screenshot and everything seems fine, except that you have Bus 6 as the input for your blue track Digitone Master, but I can’t see anything feeding Bus 6. I don’t think this is your issue though.
Yes it automatically updated it for me to 10.6 
I read the other thread and I guess we just have to wait and see if they fix the issue. I hope so.
I’ll have to rewatch your tutorial and try it again because I can’t remember what is with the Bus 6. What should the input be?
Thanks for the great YouTube tutorial. Just watched in the hope I can get my DT running properly into Logic.
Catalina and 10.6 is most likely the problem but I get distorted, glitchy sound whenever I press play. Sometimes nothing at all and then a blip of reverb / delay when I press stop. It’s driving me crazy.
Just a vent I guess. Needed to get it off my chest!
Is the the behaviour caused by Catalina / 10.6? I’ve got a feeling I’ve got some underlying setting incorrect that might be causing or adding to this.
Sounds very similar to when I used to overload the CPU years and years ago when adding one too many plug ins.
I confirm CPU is barely registering any activity so it’s not that.
Thanks. I didn’t have it working before so can’t sense check whether it’s set up properly.
Anyone know how to get a downgrade to 10.5 on Catalina?
If you have a time machine backup you could bring that back, otherwise it might be difficult 
Has anyone here had an issue where the audio coming in from the Digi is visible on the virtual instrument track, but for some reason it can’t be heard? The audio also is routed to an audio track via a bus, but the audio isn’t there either. All other audio coming into and out of Logic is acting normally, I just can’t hear the Digi even though I can see it!
It’s strange. I used some of this thread to make this work a few months ago. Saved myself a Logic template so I didn’t have to think about the setup again. Didn’t touch the setup for a while, and today I want to record projects I’ve been working on. But I can’t hear anything! It’s pretty clearly a Logic setting I am not finding here.
Anyone have any thoughts on this? Sorry if it’s not enough information, and using this as a Logic help center.
Can you clarify this? “Isn’t there” as in cannot be heard, or is it not printing any audio/waveform?
What are you monitoring the other audio through?
A few more details would be helpful.
Do you see the meters in Logic moving for the DT or just in the virtual?
I was able to see (but not hear) the audio hitting the Digitakt Plugin tracks, but it wasn’t routing to the audio tracks it was bussed to. It was properly routed to audio tracks so this wasn’t the issue. I was monitoring through my interface. I did not have it set up as an aggregate.
Honestly, I feel dumb. I had this working once just this way. After setting and resetting everything I could yesterday, I had it working again, then it stopped. I’m not sure what I did to make it work or stop working this way. Also Logic seems to have changed what it’s using for input/output on it’s own. I need to figure this out though, as I know this can work the way I want.
I think setting up and aggregate might be what I should be doing. What I would like is to be able to use the Digi via overbridge, AND use the other gear it’s controlling through my interface and monitor through it all at once. Basically, I want to completely multitrack my Dawless gear all at once. 8 tracks and FX from the Digi, then 3 stereo and 1 mono track via my interface into the computer. All audio out via that same interface.
Can you confirm that aggregate is the way to go and perhaps point me to a good way to set that up?
Yes, OB, No, n/a.
Kpucski asked essentially the same things. You can see my more detailed response to him above.
I appreciate the help!
aggregate when using OB and a separate IO
You don’t need to aggregate, though. It should work without making an aggregate device. It’s more likely that there’s a setting in logic that’s messing up: maybe look into the monitoring options?
well there was an old bug, where when switching to OB it disable some of the outs. you just had to click one back on and that fixed it. but that’s an OLD one. like a year, year and a half ago…maybe two?
hard to make THE call when we can see or hear anything. shoot a quick vid? I’m CERTAIN its a simple fix. [sorry that last bit was meant for Sacred] you’ll get sorted for sure @SacredHeartAttack 
helpful folks here
Yeah that was something I had on my A4, but that was the bug where OB had the “Measuring…” error, I think? Then opening OB control panel and disabling / enabling the channels fixed it. But I don’t think that’s what’s happening here
Right, the very first time I set it up a few months back it all just worked. I remember saying to myself “I don’t understand what everyone is complaining about”. Then yesterday, it fought me for like 3 hours before I was able to make it work for me to at least get what I wanted to recorded. All settings appeared to me to be correct.
You could try setting the outputs on the Digi audio channel to one of the outs on your other interface. I’m not 100% that it’ll work, but worth checking, if you haven’t.
Here’s a link to aggregate device if you need it. It’s pretty straightforward.
I’m certain I’ll get there too, and this forum has been a great help to me in the past so I trust it will get worked out. Let me get it all going again and see what happens. I still think an aggregate device is my best bet per how I like to work.
Ha, I was JUST looking at that page.
