Important: If your source or destination port uses a MIDI Time Piece, then you mustspecify MIDI Time Piece in the MIDI Setup dialog box (Setup menu) prior to using the Change Ports dialog box. Keep in mind that installing OMS will allow you to custom nameeach of the 8 available ports on the MIDI Time Piece. Referring to ports byname, rather than number, enhances the overall level of intuitiveness within Metroand other OMS compatible applications.
