AUM Audio => Groove Rider 2…What am I missing?
Or alternatively, Audio Interface => GR-2
After doing a ton of research looking for a groove box type app that supported both AUV3 plugins and would allow external instrument input, I plunked down the $35 for Groove Rider 2. It appeared to check all the boxes, though I couldn’t find any tutorials that actually demonstrated getting external audio recorded into a GR-2 sample, so I’m clearly at fault here if I read too much into its capabilities.
I can’t find anything definitive that this is possible, but no matter what I do, in trying to select an audio source in GR-2 it doesn’t see anything other than GR-2’s own outputs or the iPad’s microphones. It doesn’t see any IAA sources nor does it see my audio interface (Scarlett 2i4) when it’s connected to the iPad. I’ve tried specifying IAA/AB output for an AUM channel, but it shows “none connected” and the specified port still isn’t seen by GR-2.
So, can this be done or did I just waste some more money?

You would need something like the loopback feature of kq voice plugin (https://apps.apple.com/ch/app/kq-voice-plugins/id6450491216?l=fr-FR)
So I tried to access the interface again. It showed up exactly as your screenshot shows.
The only thing I did different was connecting AUM to the interface first, which is probably coincidental. Unfortunately it connects to both inputs; no way to connect to the R or L alone (My instrument is “stereo” w/separate voices R/L). Anyway, it sounds like I followed the same steps you did, but it worked – I plugged into the interface, I added a sampler to a part, then tapped on the sampler’s Edit button. This produced a blank “file.” I make sure the “In:” selector below the Record button shows “In: Audio In” (first item in the popup list.) I hit “Record” and play a couple of arpeggios and press “Record” to stop. I can then trim, normalize, save, and slice the result.
But I’d still like to do this via AUM. AUM has been my “pedal board” for 2-3 years, and I’d rather not have to try to duplicate the rig I’ve built!
But I’m pleased to get it to see my interface. Much better than nothing.
Thanks! Have you gotten this to work, or know anyone who has? I just watched Jade Starr spend 40 minutes trying unsuccessfully to use KW Voice loopback to get output from AUM into Logic!
To be fair, he had gotten it to work while prepping for the livestream, so it’s clearly possible!
Yes it works ok for me. I don't have Logic but I can play something in AUM, send the output in GR2 via Loopback and record it in the internal Sampler. I am facing however some glitches from time to time. Don't know if it is because of my iPad that is old now (2017)
@offbrand – So KQ voice loopback “in” is placed into the AUM signal chain as an effect, correct?
Where are you placing the KQ Voice loopback “out” in GR2?
FWIW, I was really puzzled when Jade placed the “out” in logic as a MIDI insert, when I would have expected it to be an audio track…
OUTSTANDING!
This works perfectly. I note that AUM syncs the tempo to GR2, so that’s something to be aware of. Wouldn’t have noticed this playing my instrument through AUM, but I tested this with a composition I’m working on in AUM, and couldn’t at first figure out why the tempo was cranked up to 120bpm. Noticed no latency at all. I can toggle the mute on the plugin in AUM and let them play simultaneously and it’s unnoticeable; I had to up the volume on the AUM output otherwise I couldn’t tell I was hearing both outputs.
Sampling is no problem either. I added a second, sampler layer to the part (Part 1) to which I added KQ Voice loopback, and specified “Part 1” as the audio source. Voilá. However I see no reason that you’d have to do it this way. You could just as easily add the sampler to some other part and point to the audio from the part with the loopback AU for the input when recording.
Thanks so much for sharing this solution!
EDIT: The tempo sync was due to the Ableton link, had nothing to do with the loopback!
I did a vid on using kq loopback to stream audio from logic to AUM. I've never used it since, as I stopped subbing to logic shortly after and never had another use for it. I think I vaguely remember that this doesn't work in the opposite direction (AUM to Logic) but I really am not sure. The vid is here anyway:
If you’re having trouble getting the interface recognized, this is a solid solution. Only downside is it sucks up 15w of power, so if you want to keep everything powered up (iPad, MIDI controller, audio interface) you need to be running at least a 65w power supply. The camera dongle is hard to find and expensive, and I’m not sure they make them for iPads w/USB-c ports.
I did see that Gavinski Tutorial.
I don’t believe the hub sucks up 15w of power. It uses a tiny amount.
What gives you the impression that it uses 15w? I used to believe something like that till it was explained to that the hubs are set up to guarantee that if you have a 100watt power supply connected, there are 15 watts available for the non-PD ports even if the PD port is attached to something sucking up 85 watts.
I got that from Anker. I was using a 30w power supply and couldn’t get it to keep the iPad charged. Contacted Anker support and they quoted the 15w figure. If you look at the listing for that hub, one of the illustrations shows a 100w power supply connected through that hub to a laptop, and indicates only 85w going to the laptop. This is all way outside my wheelhouse so I may still be misunderstanding things, but switching to a 100w power supply on my desk, or a 65w for mobile use solved my charging problem.
And yeah, I’m seeing the same thing – the name of the interface but no ports. Doesn’t seem right as everything else I’ve used sees and allows connections to all of the ports in & out on the interface.
I wonder if maybe microphone permissions were off in iOS settings before the re-install. The re-install would have then prompted to grant permissions and fixed that problem if it was the case.
[edit] nvm. Answered in another thread.
I believe that what that illustration tells us is that the maximum power sent to the PD port is 85 watts even if a 100 watt power supply is connected. It isn’t eating up 15 watts. It is ensuring that there are 15 watts available for the hub’s other ports.
I believed the same as you till an engineer explained that these hubs use very little power.
That certainly makes sense. All I know is that I couldn’t run everything (iPad, interface, and MIDI controller) with a 30w charger, and Anker claimed the hub consumed 15w. That really surprised the hell out of me, as that’s a lot of power for a fairly simple device. But I have observed that the hub gets surprisingly warm in use, if that means anything.
Excellent!!
