If I'm understanding you correctly ...

Don't route your vocal tracks to the stereo outs, or headphone outs - however it is that you do things.

i am just using the headphone outs ont the from of my 003 rack.....is there something im missing?

When you create your vocal track that you're about to record, instead of routing that track to the stereo outs (I believe it defaults to A 1-2).

Anything routed to the stereo outs will also be sent to the headphone outs.

Just change it from A 1-2 to no outputs.

Or just mute the track you're recording to. It will still record and you won't hear it, but you will hear the other tracks.

"Ditto" on the mute button, it should be that easy.

Unplug/turn off the headphones?

Yeah, he could just sing random melodys and HOPE they line up with the music when he plays it back.

Ah the mute button!

I didn't think of that because I thought the meter doesn't function when it's enabled. I thought that might cause more confusion for them.

Yes, try the mute button.
