I was wondering if you used Melodyne (a pitch shifting/pitch correction feature found in some current recording software apps) and then filtered out the individual parts of the original stereo .wav file. You could then reassemble another .wav file out of these individual tracks. The Ketron SD-7 may have a new technology to read a multitrack .wav file. I have no experience with or knew that a multi-track .wav file existed.

All I know about this is I am certainly going to investigate this new feature when I get my new Ketron SD-7 from AJ as soon as they arrive here in the US.

AJ, where did you find the multitrack wav of michael jackson ?

Would love to see how the registration process works for styles, sms and MP3s on the touch screen.

Me too Eddie

Virtually all professional audio recordings are multi-track and only get mixed down to the required number of channels (2 for Stereo) at the final mastering stage.

But that final mixing down step is the critical stage.
