Audio Interface

iPhone & iPad

Solo works with any audio interface that is fully compatible with iPhone and iPad.

We highly recommend the IK Multimedia iRig HD X.

Below is the current list of other devices that have also tested successfully with iPhone and iPad.

  • XSonic Xtone

  • XSonic Xtone Pro

  • Presonus 1824C

  • Tascam Series 208i

  • Fractal Audio FM3

  • Fractal Audio Axe-Fx III

  • Line 6 HX Stomp

If your audio interface has multiple inputs, your guitar must be plugged into input 1 for Solo to work.

Mac

Any Mac with an in-built microphone will work with Solo without requiring an audio interface. The Mac Mini and Mac Studio do NOT have in-built microphones and will require an external audio interface or USB mic to run Solo. Alternatively, if you own an iPhone, you can use the iPhone’s mic with your Mac via Continuity Camera functionality.

Any audio interface or USB microphone that is compatible with MacOS will work with Solo running on an M1, M2 or M3 Mac. To get up and running with Solo on MacOS, follow the guide below: -

  • If Solo is currently running, close it.

  • Plug your guitar into input one on your audio interface - Solo will only listen to input one, so be sure to not use any other inputs.

  • Set your input gain levels correctly on your audio interface so that you are achieving a good signal level without clipping - refer to your audio interface manual for this step.

  • Go to System Settings > Sound > Output & Input > Input.

  • Select the audio interface that your guitar is plugged into.

  • Launch Solo, it will now listen to the first input of the chosen device.

  • Be sure to calibrate the note detection sensitivity again in the app settings.

  • If you’re still having issues check your Mic Mode settings. Start a workout and check that your Mic Mode (orange, mic shaped icon in the menu bar at the top of your screen) is set to Standard and not Voice Isolation - unfortunately, due to the way Apple currently implement the Mic Mode feature in MacOS, you can only change this setting while Solo is either running a workout or calibrating Note Detection Sensitivity.
