Using the MP3 player
Quick Start
MP3 mode includes a “Phrase Trainer” function
that provides an effective way for you to practice
a song.
• The “Time Stretch” function lets you change the
playback speed of the audio file.
• The “Center Cancel” function lets you eliminate
the sounds that are panned to the center, and use
the song for “minus-one” practicing.
• The Time Stretch and Center Cancel functions can
be used simultaneously.
Using the demo song, let’s try out the Time
Stretch function and the Center Cancel function.
You can perform with the guitar etc. connected
while listening to the sound that changes the
playback speed.
Press [MP3/TRAINER] to switch to
MP3 mode.
The MP3 player screen will appear.
