Just got too frustrating so I returned it and bought a Presonus USB audio interface.
I did learn some things though. The audio out jacks from my Juno Di keyboard /synth plug into audio inputs on the audio interface. Midi from the Juno is completed routed through the USB cable that plugs directly into my PC. Since I only record with the keyboard OR guitar at one time, I only need 2 1/4” jacks on my audio interface to record audio!
