Hello again, all my SynthZone friends!

I have recorded a song on my 7000 and have now saved it in Technics format on a floppy disk. What I would like to do now is record myself singing it, but I just don't know how to do this. I have my microphone attached to the proper spot on the back of the keyboard, and the "mic" button pressed and lit on the front. When I push the "Play" button, I can hear what I recorded and if I sing along through the mike I can also hear that as I perform, but I do not know how to save both together and then play it all back.

I also tried to copy the recorded song to my computer and seem to have trouble doing that, too. Apparently I am neither an expert with the keyboard nor the computer--but that should come as no surprise! LOL
Any help you can provide would be most appreciated. Thanks in advance.

Ted
