I have a Jam too and it’s very simple: just connect your Jam and make sure you’re getting the blue indicator on the Jam before starting Cubasis. Start Cubasis and the indicator should turn green. Add a new track and choose MONO input 1 under routing and you’re all set. Of course you can monitor you signal by turning on the speaker icon on the channel fader pull-down tab. The device name, Jam, no longer shows up in the routing section and the Stereo option should be greyed out.
