The manual here is specifically for the I5s keyboard model, but I would think that most of it would equally apply to the I5m unit.

Hope this helps.

For the editor give this a go:

Scroll about a third of the way down the page. Good luck.

P.S. support@korgusa.com can e-mail you a pdf of the i5m manual.
