This is what I use Al, straight into the 3.5mm line-in channel on the PC.
https://www.gearslutz.com/board/electronic-music-instruments-electronic-music-production/529705-soundcraft-notepad-124-a.htmlUsing Adobe Audition.
Rip your BT from CD onto computer.
Start a new recording in Audition.
Plug guitar into mixer, set input channel on Audition to line-in, set level at mixer.
Put your BT onto track 1 in stereo. (Right click on track and 'add audio' )
Record your new guitar masterpiece onto track 2 . You can put effects on after you've recorded it.
Shads echoes are available as a VST plug-in, PSP608 if you wish, it's what I use.
Piet does a eTap VST plug-in but it doesn't seem to work with Audition.
Anyway, that's what I do.
These days, I suppose, USB things are around but I've had no experience of them so I stick with what I know.
