AXE I/O One Output Issue

[punchy712]

Hi, I purchased a AXE I/O One interface a couple of weeks ago and I'm running into an issue that I'm hoping someone can help me figure out (at least whether it's an issue or a limitation). Note that I contacted support about this on June 4th and have heard nothing from them.

My understanding is that the interface has 3 outputs (two on the back and amp out on the front). My basic question is, can all 3 outputs be used at the same time? I would assume so, but that doesn't seem to work for me.

I'm using Ableton Live 11 on my MacBook Pro M2 on Mac OS Ventura 13.4. The interface is configured in Ableton and it detects 4 outputs correctly. My problem is that I'm only able to get output from Amp Out (output 3) if I disable outputs 1 and 2. If I enable all outputs in Ableton then I can only get sound out of outputs 1 and 2 (which are going to my monitors).

What I'm trying to do is this:
- have an audio track set to output to Amp Out (the audio here would be a pre-recorded guitar DI)
- Amp Out goes to the input to a guitar pedal
- guitar pedal output goes to AXE I/O input
- AXE I/O input is routed to a second audio track in Ableton (configured with an Amp Sim like Tonex or AmpliTube for example)
- this second audio track would be set to output to outputs 1/2 (or to master which is configured to outputs 1/2)

Is the above doable because so far I haven't been able to get it working.

Same problem here. Did you hear back from support on this?

Ableton on Mac doesn't like the fact that the AXE I/O has an uneven number of inputs and outputs. I found a workaround is to use the Audio MIDI Setup app (in the Applications/Utilities folder) to create an Aggregate Device.

In the Aggregate Device, click the checkboxes to use AXE IO One, MacBook Pro Microphone and MacBook Pro Speakers.

Where you see the Subdevices, you may need to drag them left and right so that the AXE IO One is the leftmost.

Then back in Live, Input 1 will be the instrument input, Input 2 will be the Mac's microphone, Outputs 1 & 2 will be the main outs, Output 3 will be the amp, and Output 4 will be the left Macbook speaker.

In Live's audio settings you can (and probably should) disable the ins and outs you won't use - so disable Stereo Inputs 1 & 2, Mono Input 2 (Macbook mic), Stereo Out 3 & 4, Mono Out 4 (Macbook speaker).
