Muting Some Parts Before Playing (Track Buttons)
With commercially available music files for piano lessons, the part for each hand can
be played back independently. This makes it easy to practice hands separately. For
example, you can follow along with your right hand while you listen to that same
right-hand part be played, or you can practice the left-hand part while the right-hand
part plays.
A music file for piano lessons may be assigned to the five Track buttons as shown below.
By using these Track buttons, you can eliminate the sound of specific parts. This is
referred to as “muting.”
By recording your own performances to the Track Buttons in this fashion, you can
mute parts the same way. For details, refer to “Recording While Selecting the Track
Buttons (Redoing Recordings)” (p. 81).
1. Select the song that you wish to play back (p. 54).

Selecting the Part that You’ll be Playing

2. Press any one of the Track buttons to make the button’s indicator light go

dark.

The sound for the selected part no longer plays.
For example, when practicing the right hand, press the [4/Upper] button.
When you play back the song, the right-hand performance will not sound. Practice
your right-hand performance along with the left-hand playback.

Playing Back a Song

3. Press the [ (Play/Stop)] button.
The song will begin playing back.
The part you selected in step 2 will not sound.
Once again press the button you selected in step 2. The button’s indicator will light
up, and the part will be heard once again.
Even while the song is playing, you can press the track buttons to mute or un-mute
the sound.

Stopping the Song

4. Press the [ (Play/Stop)] button.
The song will stop.

If a single Track button
includes more than one
instrument and you want to
mute just one of those
instruments, take a look at
“Modifying the Settings of
Each Part” (p. 100).
When a single Part is not
played, it is called “Minus
One.” Using Minus One, you
can mute out a particular
instrument and play the part
yourself.
When playing back SMF files
for Roland Piano Digital series
instruments, and the [3/
Lower] button and [4/Upper]
button do not correctly control
the lower/ upper
performances, please change
the “Track Assign” settings.
Please refer to “Changing the
Parts Assigned to the Track
Buttons During SMF Playback
(Track Assign)” (p. 142).
You can adjust the balance
between the keyboard and
song volume levels. Check out
“Adjusting the Volume
Balance for Each Performance
Part (Part Balance)” (p. 52).
