How can I record a synth stereo audio output into garageband ?

Both channels are being picked up by the interface in stereo.

I'm not sure if there is something missing in the picture. Let me verify:

• Your synth has two mono audio outputs, one is labeled left and one is labeled right.
• You connect the left output to the input channel 1 (mono) on your audio interface and the right output of your synth to the input channel 2 (mono) of your audio interface.
• Now in GarageBand you choose that audio interface in the Preferences
• You create a new Track and in the Smart Controls Inspector (see picture), you select for the Input Parameter that audio interface, and click that button to its left so its shows that double circle (which means stereo).
• This way, GarageBand records a Stereo Track (2 channels), the left synth output as channel 1 (left) and the right synth output as channel 2 (right)

Hope that helps

Late response on this, so hoping you resolved this since then. To get the left stereo channel on Input 1 and the right stereo output of the synth on Input 2, Pan the signal going into input 1 to the left and conversely, pan Input 2 hard right. Otherwise, use a single mono input into GB and pan it where you want in the mix.
