Roland KF-90 Manuale Utente

With commercially available music files for piano lessons, you can play back 
the part for each hand individually. Playing the internal song’s right-hand 
part with your right hand, and the song’s left-hand part with your left hand 
allow you to practice each hand’s part separately.
For instance, a music file for piano lessons may be assigned to the five Track 
buttons as shown below.

fig.03-06.e

By using these Track Buttons, you can play back with the sound of a specific 
part removed.

The removal of this specific part’s sound is referred to as “muting.”

By recording your own performances to the Track Buttons in this fashion, 
you can mute the parts the same way.

The 5 Track buttons screen appears.

If a single Track button 
includes more than one 
instrument, and you want 
to mute out just one of 
those instruments, take a 
look at “Changing the 
Settings of Each Part” (p. 
120)

A Track button has 
performance data when 

<

it.
Track buttons for which 

<

no performance data.

You can change the volume 
balance for the keyboard 
and the song. Check out 
“Changing the Volume 
Balance for the 
Accompaniment and 
Keyboard” (p. 81).
