After I recorded bars 1 to 4 I heard my first recording during playback. During the first test, bars 1 to 4 were recorded both times and my second recording was merged with the first recording. During the second test I listened to bars 1 to 4 as a lead in to my second recording and the second recording did not start until bar 5.

Notice my "Overdub during playback" checkbox is grayed out so I can't select it. I suspect that is a response to the audio interface and may vary from interface to interface. In my tests I was using a USB gaming headset with microphone and headphone capability. It is not unusual to both listen and speak at the same time while gaming.

Sound on sound use to be a common technique. The technique was invented by Les Paul in 1949 +++ Les Paul Sound-On-Sound +++. He is the only person that's in the Rock & Roll,Country and Inventor Hall of Fame.

For a fun little sound-on-sound test try recording a count of 4. Only record the numbers 1 and 3 the first pass and the numbers 2 and 4 the second pass. Do you stay on the beat? Are the two recordings equal in volume and tone? It's more difficult than you think until you become proficient but it can be done.
