Record from USB on PC; Audition 13 2020

Audition does not have the capability to record MIDI so you need to connect the Audio outputs of the keyboard to the audio inputs of your computer; you cannot use the USB output from your keyboard, which is for MIDI only.

Ideally, you would have the audio going from your keyboard (two channels, for stereo) to an external USB interface (minimum 2 channels model) and this interface can be connected to your computer via USB and Audition can record it.

One caveat: reading the detailed specs for your keyboard here I see the only audio outputs are for headphones.  You will need to carefully set the output level of the single miniature stereo jack so that it is not too loud for the input of your interface or your computer or you will be recording a potentially high level of distortion.

For a start, that video relates to a Mac, not a PC.

As far as the Roland FP10 is concerned, the spec says 'Built-in Bluetooth MIDI/USB MIDI interface for connecting to Garageband, computers, DAW software'. What this means is that you can send MIDI signals across the USB port, not audio. Audition doesn't use MIDI as an input source at all, as strictly speaking it's an audio editor, not music creation software.

What you saw in that video was somebody recording a couple of tracks - that we never heard, so we don't know what they were - into Audition, and exporting them. They appeared to show a Yamaha keyboard plugged into a laptop, and that it has been aggregated into the available sources. This means that keyboard either has the ability to output audio in a digital form via USB (extremely unlikely) or, as I suspect, something completely different is happening that we aren't seeing.

So I'm afraid that the bottom line is that you can't do this - and that's not because you haven't got a Mac. It's because your keyboard only outputs MIDI switching data, and that's not audio. The only way you can record audio from your keyboard is via the headphone output, which you can connect to a normal audio input, just as you would any other source.
