Volume Control
During DISK ORCHESTRA playback use the RHYTHM volume control
to adjust the volume of the drum and percussion parts, the CHORD 2 volume
control adjusts the volume of the main left- and right-hand parts, the CHORD
1 volume control adjusts the volume of all other parts except the bass, and the

When a different song is selected the volume settings will correspond to
those in the song data, regardless of the positions of the volume controls.
Guided Right- and Left-hand Practice
With this feature, the PDP-400 waits for you to play the appropriate keys
before playing ahead, so you can learn to play the piece at your own pace.
Press the [GUIDE] button so that its indicator lights to turn the guide mode
on. The settings of the [RIGHT/1TR] and [LEFT/2TR] buttons will then deter-
mine whether the guide function operates for the left-hand part only, the right-
hand part only, or both the right- and left-hand parts, as listed to the left.
When you press the [START/STOP] button to begin playback, the introduc-
tion will play automatically but then the PDP-400 will stop and wait for you to
play the next key(s). As you play the appropriate keys, the piece will continue,
pausing until you play the right keys each time.
As with automated performance, the song will stop automatically when the
end is reached, or it can be stopped at any time by pressing the [START/STOP]
button.
NOTES
Disk Orchestra playback tempo can be set to any desired value after a song
has been selected by using the TEMPO [
] and [

The [PAUSE], [REW] and [FF] buttons will not operate when the guide func-
tion is in use.
