Babyface>Guitar Amp App>Auria=Channel 2 Mono input?

[Blevitt]

I'm a brand new member trying to get up and running, and could use some help!

I have an RME Babyface interface for my guitar and bass. This works great when I just record directly. Auria sees the input on Channel 2 and I am able to record a mono track. As far as I know, the instrument output from the Babyface is only available as a mono output on channel 2.

But when I run my guitar through JamUp Pro or Yonac ToneStack, using either IAA or Audiobus, Auria automatically creates a track with a two channel stereo input. However, my guitar only records on channel 2, and nothing on the second channel.

How can I either create a two channel stereo output from RME's TotalMix FX app, or how can I duplicate the one channel of the two stereo channels I can record, and create a full stereo track?
