Drambo and Fireface UCX bug
I use drambo a lot and I find I’m always having to do this weird dance when I first start the program after plugging in my USB sound card (RME fireface UCX). Often only the first two outputs appear, I have to go in to another program like Cubasis, play something out of all 18 outputs (it has an ADAT expander I use for talking to my ES-8 in my modular) and then after quitting and restarting drambo all the outputs will show and work properly - though I still have to go manually through my patch and re select all the external outputs.
Does anyone else get this problem with external sound cards? I really love Drambo and I don’t want to ditch my RME… I think it’s a drambo issue because Cubasis seems to work first time.

I don't have this interface, but I've never had an issue with my outputs on my MOTU Ultralite Mk5 or an iConnectivity Audio4+. The latter has about 20 I/O (it supports bridging two computers/iPads) and they have shown up fine. The few bits of weirdness I've run into seemed to just be iOS in general across iOS hosts (Loopy Pro, AUM, apeMatrix, Drambo).
It's possible something has been introduced just recently because I haven't used an interface in a few months. Or maybe something weird with just this interface and Drambo somehow.
Btw, it sounds like you are using the "Audio Input" module, but you might want to try using the audio input options from clicking on the track number in the module view (the immovable left-most module). That seems to retain interface selections even if you unplug/plug in audio interfaces.
Sometimes it retains it but it doesn’t work, like the graphic stays saying what it should but it doesn’t actually supply audio. Sometimes it just doesn’t list the outputs. I’ll moan at RME too but they seem pretty useless these days which is ironic given their reputation for solid driver support. Last couple of times I’ve contacted them they blame Drambo / iOS.
Feel like a Mexican bug standoff
Btw yeh using the audio input module because I have quite an esoteric template going that routes all the inputs to a single track and in to loopy pro then out to individual tracks for effects processing. It’s great being able to jam live hit a button and get a 4 bar loop of what ever I just did, queue mix the next thing and then auto fx mix the next thing in…… when it works 😂
Oh yeh that was me, I kind of hoped a raft of iOS / Drambo / RME updates would fix it but it still persists. I have the card set to multichannel.
Next time I'm in front of it I'll try seeing if launching drambo before plugging in the card makes a difference.
Hi, I have same issue with zoom livetrack l6 … to work correctly with drambo i have to open loopy pro And closed before starting drambo… did you resolve the issue ?
I still have the bug, it's really frustrating. I normally have to start cubasis a few times, restart Drambo, turn everything off and on and then eventually it all works. Wonder if @giku could help?
Do you AUM?
If so I've noticed since iOS 26 that AUM has an option to select whatever audio interface is connected to the iPad.
Try opening that first and then selecting your audio interface.
I have AUM but the method I've settled on is to just run everything in and out of Drambo. I'm on a A12Z iPad Pro from 2020 and iOS 17 because I'm too scared to update.
Not to run dRambo in AUM, just use AUM to select the audio interface and carry on using dRambo standalone.
I have two audio interfaces connected to my iPad, an EVO16 and a Zoom U-44.
I keep them both connected, I used to have to disconnect and reconnect the EVO16 so that it's audio inputs and outputs could be seen,
it used to default to the Zoom U-44, now I simply open up AUM and select the audio device I need for either the inputs or outputs.
I default to the EVO16 for the inputs and outputs and the Zoom U-44 is being used for it's midi ports.
The EVO16 doesn't have midi in and out.
There's also an audio input picker in the control center now in iOS/iPadOS26. The catch is it only shows up if there's an audio app running, so you won't see it until after you open Drambo. If the interface is seen by the OS then it should show up there, and hopefully be able to be selected without having to open another app.
To be clear the bug is not that the ucx is unused just that only the first two outputs are exposed. Instead of showing 18 in 18 out it shows up as either two in two out or 18 in two out.
I’m considering upgrading to 26 but I’m on a 2020 ipad pro 12” gen 6gb a12z and a bit worried that it won’t fix the bug but will make it run gloopy.
Once I get all the inputs outputs recognised the rest of the session is productive so I don’t want to upset the apple cart… does anyone else have good experiences with older hardware on ipados 26? On reddit I see mostly horror stories.
