4.1 Setting the MIDI channel
.
MIDI features sixteen MIDI channels, numbered
1-16. The connected devices must be set to use the
same MIDI channel, otherwise no sound will be pro-
duced.
In a setup where you wish to play the HP-137 and also
have another MIDI-equipped instrument or sound
module play the same notes, you must set the channel
used for reception on your external device to the same
channel that the HP-137 uses for transmission.
If you use another MIDI keyboard as a master instru-
ment and want the HP-137 to play these notes, you
need to set the channel used for reception on the HP-
137 to the same channel that the master keyboard is
transmitting on.
If you want to use the HP-137 as tone generator for
an external sequencer, select the MIDI channel
assigned to the track who's data the HP-137 should
play back.
Note: When the HP-137 is turned on, Channel "1" is
selected.
1. Press and hold the volume button.

5.1 Troubleshooting
If you are encountering problems with the HP-137,
please read the section below before assuming that
there is a malfunction.
The piano cannot be switched on
Is the power cord properly connected? (p. 5)
No sound is produced
Is the volume knob set to the minimum position? (p.
5)
Are headphones connected? (p. 6)
Is Local On/Off set to "Off"? (p. 13)
The pitch of the keyboard sounds incorrect
Is the Master Tuning setting correct? (p. 10)
Is the Transpose setting correct? (p. 10)
Bass notes sound wrong/buzzing or vibration
occurs
If you can't hear the problem in the headphones:
When playing at high volumes, resonance may occur
in the piano itself or in objects near the piano. At
times, other objects in the room, such as fluorescent
lights or glass doors, could start vibrating. This
becomes more noticeable when sounding the lower
frequencies at high volume. To minimize such
unwanted resonance, please observe the following:
Locate the instrument at least 10~15 cm away from
the walls.

2. While still holding the volume button, press the
key corresponding to the desired MIDI channel
(between the C5 and the D#6).
Select the desired MIDI channel
The MIDI transmit and receive channel will switch to
the number that corresponds to the note you pressed.
Note: Refer to "Functions assigned to the keyboard" on
page 16 for the exact location of the keys you need to press.
» Reduce the volume.
+ Increase the distance from the object that is resonat-
ing.
If you can hear the problem in the headphones, there
may be another reason. Please contact your dealer.
in the upper range, the sound changes abruptly
beyond a certain key
On an acoustic piano, notes in the upper one and a
half octaves of the keyboard continue to sound until
they decay naturally, regardless of the damper pedal.
There is a difference in the timbre as well. Roland
pianos faithfully simulate such characteristics of the
acoustic piano. On the HP-137, the range that is unaf-
fected by the damper pedal will change depending on
the Key Transpose setting.
When the HP-137 is connected to an
external device
No sound is produced
Is the power to all equipment turned on?
Are the connections between HP-137 and the MIDI
sequencer or the other external devices correct? (p.
13)
Is the MIDI channel setting correct? (p. 15)
Is the Omni On/Off setting correct? (p. 14)
