from among the note information of a tune sent from the 
computer.
■Specifying the Navigate Channels
From among the 16 available channels (numbered 01 to 16), 
you can specify any two neighboring channels (such as 05 
and 06) as navigate channels. The smaller numbered channel 
is the navigate (L) channel, while the larger numbered 
channel is the navigate (R) channel. Specifying the navigate 
(R) channel will automatically configure the navigate (L) 
channel as well.

Playing the Part on the Keyboard
You can turn off the sound on one or both of the navigate 
channels and play the cancelled part on the keyboard 
yourself.
1.Press bn to select the channel setting you want

described below.
 If you turn off one channel, you can play the cancelled 
part on the keyboard using the same tone as the 
channel you turned off. If you turn off both channels 
(option (3)), what you play on the keyboard sounds 
using the tone of the navigate (R) channel.There are times when exchanging data with a computer when 
you may not want the Digital Keyboard to sound notes you 
play on its keyboard. The local control setting lets you do just 
that.

You can transfer sampled sounds, recorded songs, and other 
data in Digital Keyboard memory to a computer for storage. 
You also can load standard MIDI file (SMF) data to the Digital 
Keyboard, which greatly expands the Song Bank songs 
available to you.
A special Data Manager application is required in order to 
transfer data to and from the Digital Keyboard.
The same types of data that you can store to or recall from an 
SD memory card (page E-53) can be transferred to and from 
the Digital Keyboard. Note, that recorded song data can be 
transferred to a computer in the Digital Keyboard’s native 
format only. You cannot save recorded song data to a 
computer as a standard MIDI file (SMF format).

display.A Step Up Lesson is in progress and the Digital Keyboard is waiting 
for you to play the next note in the song. To stop this from happening, 
cancel the lesson (page E-33).
Screen contents are visible only from straight ahead. This is dues to production limitations. It does not indicate malfunction.
Sound
Nothing happens when I press any keyboard key. Adjust the main volume setting (page E-9).
 Check if something is plugged into the PHONES/OUTPUT jack (
em) 
on the back of the Digital Keyboard.
 If there is no sampled sound in memory, nothing will play if you
