Hi Deane ,
no expert on this, I tried the following.
Press recording button.
Pressed (rec) Play Pause icon to start recording.
Pressed Stop Icon to end the recording.
Pressed Exit
Pressed the Player button ( above recording button)
Sequencer screen pops up.
You can press play either , via the screen icon or the actual play audio button.
To find your recording, press the icon that says Audio and has that little blue picture with the squiggle thu it.
Up pops your saved recording.
Default on mine appears to be USB 1. That can be changed on the record screen, via the drop down menu. Top r/h side.
Setting.
Also your recording format etc can be changed.
Hope it helps.
