Thanks for your answers.

What is W10?

Yes, I do set input echo to ON.

What is and OP?

What audio interface would you recommend for me to be able to do input monitoring?

I use Windows 10 with Cakewalk by bandlab.  My sound card is M-Audio Delta 66, which has a hardware breakout box.  I record audio via a microphone and a single-channel mic pre-amp which has phantom power.  I use an old Sony consumer reciever to play back through speakers or earphones.  I formerly used Sonar 4 Producer Edition, and I have Scott Garrigus' book.  I recently downloaded the current version of Cakewalk by Bandlab.

I use aux sends to allow my vocalist to hear previously recorded tracks in her earphones while recording new harmonizing vocal tracks.  But I also want the vocalist to hear her voice in the eaphones as it is being recorded, as she lays down the harmony tracks.

I have read the section on input monitoring in the documentation, but I can't make it work.  Part of my confusion is that there are settings for the soud card, other settings for audio in Windows, and sound card-related settings in Cakewalk.

How can I set up this recording input monitoring?

It will be best to answer my question as though I know nothing about sound recording or the software.  It's prety close to the truth.

Thanks in advance.
