There is an error in the manual.
Under the heading
Playing from the Computer Hard Drive, the manual states: "Click the Select Hard Drive button that opens a dialog box to allow selecting one or more .cdg files on the hard drive. You can change the drive and directory that appears.
Click the song filename
(one at a time) in the dialog box Files list that you want to play, then click the Open button.
Click the Play button to begin playing the
selected song files back-to-back. (This is the error, it should say "file." not "files back-to-back"). While playing the display changes to full screen (see at right), appearing just like a Karaoke Player.
The Spacebar will not stop playing.
This is because only one song is playing and the Spacebar will not advance play to the next song.
Press the Esc key (upper left of keyboard) to terminate playing."
I apologize for the error in our manual.
We are working on a future upgrade (V2.3) to Microstudio and its play code that should allow selecting multiple songs from the hard disk and placing them into a list to play back-to-back. There are problems with Windows and the order you "think" you selected songs in. Thus, we need to display the songs in the order Windows reads them in from the hard drive, and allow you to move them up or down the list into the order you desire before playing.
I hope this helps.
