their location or position does not interfere with  
their proper ventilation.  
• If a battery has leaked, use a soft piece of cloth  
or paper towel to wipe all remnants of the  
discharge from the battery compartment. Then  
install new batteries. To avoid inflammation of  
the skin, make sure that none of the battery  
discharge gets onto your hands or skin. Exercise

Important Notes  
291a  
In addition to the items listed under “USING THE UNIT SAFELY” on page 2-3, please read and observe the following:  
Power Supply  
Placement  
301  
352a  
Do not connect this unit to same electrical outlet that is  
being used by an electrical appliance that is controlled by  
an inverter (such as a refrigerator, washing machine,  
microwave oven, or air conditioner), or that contains a  
motor. Depending on the way in which the electrical  
appliance is used, power supply noise may cause this unit  
to malfunction or may produce audible noise. If it is not  
practical to use a separate electrical outlet, connect a power  
supply noise filter between this unit and the electrical  
outlet.  
This device may interfere with radio and television  
reception. Do not use this device in the vicinity of such  
receivers.  
352b  
Noise may be produced if wireless communications  
devices, such as cell phones, are operated in the vicinity of  
this unit. Such noise could occur when receiving or initi-  
ating a call, or while conversing. Should you experience  
such problems, you should relocate such wireless devices  
so they are at a greater distance from this unit, or switch  
them off.  
302  
354a  
The AC adaptor will begin to generate heat after long  
hours of consecutive use. This is normal, and is not a cause  
for concern.  
Do not expose the unit to direct sunlight, place it near  
devices that radiate heat, leave it inside an enclosed  
vehicle, or otherwise subject it to temperature extremes.  
Excessive heat can deform or discolor the unit.  
303a  
The use of an AC adaptor is recommended as the unit’s  
355b  
power consumption is relatively high. Should you prefer to  
use batteries, please use the alkaline type.  
When moved from one location to another where the  
temperature and/or humidity is very different, water  
droplets (condensation) may form inside the unit. Damage  
or malfunction may result if you attempt to use the unit in  
this condition. Therefore, before using the unit, you must  
allow it to stand for several hours, until the condensation  
has completely evaporated.  
304a  
When installing or replacing batteries, always turn off the  
power on this unit and disconnect any other devices you  
may have connected. This way, you can prevent  
malfunction and/or damage to speakers or other devices.  
307  
Before connecting this unit to other devices, turn off the  
power to all units. This will help prevent malfunctions  
and/or damage to speakers or other devices.  
358  
Do not allow objects to remain on top of the keyboard. This  
can be the cause of malfunction, such as keys ceasing to  
produce sound.  
Maintenance  
401a  
401a  
For everyday cleaning wipe the unit with a soft, dry cloth  
or one that has been slightly dampened with water. To  
remove stubborn dirt, use a cloth impregnated with a mild,  
non-abrasive detergent. Afterwards, be sure to wipe the  
unit thoroughly with a soft, dry cloth.  
402  
Never use benzine, thinners, alcohol or solvents of any  
kind, to avoid the possibility of discoloration and/or defor-  
mation.  
Repairs and Data  
452  
Please be aware that all data contained in the unit's  
memory may be lost when the unit is sent for repairs.  
Important data should always be written down on paper.  
During repairs, due care is taken to avoid the loss of data.  
However, in certain cases (such as when circuitry related to  
memory itself is out of order), we regret that it may not be  
possible to restore the data, and Roland assumes no  
liability concerning such loss of data.  
4
Additional Precautions  
551  
Please be aware that the contents of memory can be  
irretrievably lost as a result of a malfunction, or the  
improper operation of the unit. To protect yourself against  
the risk of losing important data, we recommend that you  
periodically write down important data you have stored in  
the unit's memory on paper.  
552  
Unfortunately, it may be impossible to restore the contents  
of data that was stored in the unit’s memory once it has  
been lost. Roland Corporation assumes no liability  
concerning such loss of data.  
553  
Use a reasonable amount of care when using the unit’s  
buttons, sliders, or other controls; and when using its jacks  
and connectors. Rough handling can lead to malfunctions.  
556  
When connecting / disconnecting all cables, grasp the  
connector itself—never pull on the cable. This way you will  
avoid causing shorts, or damage to the cable’s internal  
elements.  
558b  
To avoid disturbing your neighbors, try to keep the unit’s  
volume at reasonable levels (especially when it is late at  
night).  
559a  
When you need to transport the unit, package it in the box  
(including padding) that it came in, if possible. Otherwise,  
you will need to use equivalent packaging materials.  
561  
Use only the specified expression pedal (EV-5; sold  
separately). By connecting any other expression pedals,  
you risk causing malfunction and/or damage to the unit.  
Handling CD-ROMs  
801  
Avoid touching or scratching the shiny underside  
(encoded surface) of the disc. Damaged or dirty CD-ROM  
discs may not be read properly. Keep your discs clean  
using a commercially available CD cleaner.

What is PLAY mode?  
This is the mode in which you play the PC-50.  
In PLAY mode, playing the keyboard will transmit note messages to play the MIDI device.  
In PLAY mode, you can play the keyboard to produce sound on a connected sound module, and  
also use various other functions, such as operating the Pitch Bend/Modulation Lever to change the  
pitch of the currently sounding note (Pitch Bend), adding vibrato (Modulation), or switching the  
octave (Octave Shift).  
In this mode you can also specify the MIDI transmit channel, and transmit program changes,  
parameters, or start/stop messages.  
To switch the PC-50 to PLAY mode...  
When you turn on the power, the PC-50 will start up in PLAY mode.

When you turn on the power, the PC-50 will start up in PLAY mode.  
What is PLAY mode? (p. 41)  
In PLAY mode, playing the keyboard will transmit note messages to play the connected MIDI  
device.  
In order to transmit MIDI messages from the PC-50, perform the following steps.  
1
Set the MIDI channel the PC-50 will use to transmit to the same channel on the sound module  
(software) is using to receive on.  
Use MIDI Channel mode to set the MIDI transmit channel.  
(Setting the MIDI Transmit Channel (p. 45)).

Select a sound on your MIDI sound module.  
(Selecting Sounds on a Sound Module (p. 46)).  
Once you have finished making settings, try playing the keyboard.  
When you play the keyboard in PLAY mode, MIDI messages are sent to the sound module  
(software).  
* Since the PC-50 does not contain a sound generator, you cannot play MIDI data using the PC-50 alone.  
43  
   
Use MIDI functionality  
Features Useful When Playing  
Move the Pitch Bend/Modulation Lever (left or right) to transmit Pitch  
Bend messages, and apply subtle pitch changes to notes.  
* The amount of pitch change (“bend range”) depends on the settings of  
your sound module.  
Applying Pitch Changes to Notes  
(Pitch Bend)  
Push the Pitch Bend/Modulation Lever away from you to transmit Modu-  
lation messages (CC#01), changing the sound in real time (usually by add-  
ing a vibrato effect).  
* The type of change this produces in the sound depends on the settings of  
your sound module.  
Modifying the Sound of Notes  
(Modulation)  
If a pedal switch or foot switch (one from the DP series or BOSS FS-5U;  
sold separately) is connected to the rear panel HOLD jack, you can press the  
Adding a Sustain Effect to Notes foot switch to make notes continue sounding even after you remove your  
(Hold)  
hand from the keyboard (the Hold function). This will transmit the MIDI  
message Hold 1 (CC#64). The Hold On message (data 127) is transmitted  
when you press the pedal, and Hold Off (data 0) when you release the pedal.  
Controlling the Volume or Timbre If an expression pedal (EV-5; sold separately) is connected to the rear panel  
of the Sound  
EXPRESSION jack, you can use the pedal to control the volume or tone.  
(Expression)  
You can press [OCTAVE -] or [OCTAVE +] to raise or lower the pitch range  
of the keyboard (the Octave Shift function).  
Press [OCTAVE -] once to lower the pitch range one octave. Press it once  
again to lower the range an additional octave. Permissible settings for this  
range from -4 to 5 octaves. [OCTAVE -] or [OCTAVE +] will light according  
to the current Octave Shift setting.If you simultaneously press [OCTAVE -]  
and [OCTAVE +], the Octave Shift setting will be reset to 0, restoring the nor-  
mal pitch range of the keyboard.  
Changing Octaves  
(Octave Shift)  
While playing the keyboard, move the Pitch Bend/Modulation Lever to  
the left to lower the pitch of the currently selected patch, or to the right to  
raise its pitch. This is known as pitch bend.  
You can also apply vibrato by gently pressing the Modulation Controller.  
This is known as modulation.  
If you push the lever away from you and the same time move it to the right  
or left, you can apply both effects at once.

Selecting Sounds on a Sound Module  
—Transmitting Program Change / Bank Select Massages  
To select a sound on your MIDI sound module, transmit a Program Change.  
To select a sound from a different bank, first transmit a Bank Select message that switches the bank.  
Then transmit a program change.  
* You must transmit the Bank Select message before transmitting the Program Change message.  
What is a bank?  
MIDI sound modules organize their numerous sounds in various groups according to the category of  
sound. These groups are called “banks.”  
Program Change messages can only select sounds within the same bank, but by using these in  
conjunction with Bank Select messages, you can select different variations of sound.  
* The way in which sounds are organized will differ for each sound module. For details, refer to the owner’s  
manual of the sound module you are using.

Is the CD-ROM correctly inserted into your CD-ROM drive?  
Installation is not possible unless the CD-ROM included with the PC-50 is inserted in your CD-  
ROM drive. Make sure that the CD-ROM is correctly inserted into your CD-ROM drive.  
Are you installing the software from a networked CD-ROM drive?  
The software cannot be installed from a networked CD-ROM drive.  
Be sure to close all other programs before installation.  
Is the CD-ROM or the lens of the CD-ROM dirty?  
If the CD-ROM or the lens of the CD-ROM drive is dirty, the installer may not work correctly.  
Clean the disc and/or lens using a commercially-available CD cleaner or lens cleaner.  
Is your computer’s power-conservation mode turned off?  
If power-conservation settings are enabled on your computer, please disable any such settings.  
(For the procedure, refer to the owner’s manual of your computer.)

Troubleshooting  
Problems when using the PC-50  
036  
037  
In Windows, did you make the setting described in “Giving priority to background  
services”?  
In order to ensure that MIDI processing occurs smoothly, make the setting described in “Giving  
priority to background services.”(Windows XP(p. 18), Windows 2000(p. 22))  
038  
Can’t play back / record MIDI  
039  
040  
041  
042  
Did you plug in the USB cable, or unplug it while an software was running?  
Exit all softwares that are using the PC-50, and exit all softwares that are using the PC-50, and  
turn the PC-50’s power off, then switch it on again.  
Is your computer in Suspend or Sleep mode?  
If so, get your computer to resume normal operation, then exit all softwares that are using the  
PC-50. Next, turn the PC-50’s power off, then switch it on again.  
Have you specified the MIDI data output destination in your playback software?  
For some software, you may need to specify the PC-50 as the output destination for MIDI data.  
Was the driver installed correctly?  
In order for you to play back audio data via the PC-50, the driver must be installed. For  
installation and settings, refer to “Getting Connected and Installing Drivers” (Windows: p.  
14/ Macintosh: p. 27).  
043  
Are you running multiple softwares?  
If multiple softwares are running simultaneously, an error message may appear. If this occurs,  
click [OK] and exit the other softwares.  
Even if an software window is closed, it is still running if it appears in the taskbar. Be sure to  
exit unneeded softwares displayed.  
044  
Playback or recording halts midway through, and then becomes  
impossible  
045  
Was a heavy processing load experienced while using the PC-50, such as accessing the  
CD-ROM drive or a network?  
If an operation involving a heavy processing load is performed while the PC-50 is in use, it may  
not operate correctly. If this occurs, stop playback/recording, and then try resuming playback/  
recording. If you are still unable to play back/record, exit all softwares that use the PC-50,  
switch off the PC-50, then turn it on again.  
77  
   
Troubleshooting  
046  
Operating system becomes unstable  
047  
Operation becomes unstable when the computer is started up with the PC-50 already  
connected  
Please start up your computer with the PC-50 disconnected, and then connect the PC-50. On a  
computer that uses a USB keyboard, starting up the computer with the PC-50 already connected  
may cause operation to become unstable. In this case, start up the computer with the PC-50  
disconnected, and then connect the PC-50.

<Example4> What is the nibble-expressed value of decimal 1258?  
1258 ÷ 16 = 78 (quotient) ... 10 (remainder)  
78 ÷ 16 = 4 (quotient) ... 14 (remainder)  
Decimal and Hexadecimal table  
(An “H” is appended to the end of numbers in hexadecimal notation.)  
4 ÷ 16 = 0 (quotient) ... 4 (remainder)  
From the preceding table, 0 = 00H, 4 = 04H, 14 = 0EH, 10 = 0HA.  
In MIDI documentation, data values and addresses/sizes of Exclusive messages,  
etc. are expressed as hexadecimal values for each 7 bits.  
The following table shows how these correspond to decimal numbers.

The decimal expression of the MIDI channel, program change, etc., is one  
greater than the decimal value shown in the table above.  
The hexadecimal expression for each 7 bits allows a maximum of 128 steps (0--  
127) to be expressed by one byte of data. Multiple bytes are used if the data  
requires greater resolution than this. For example, a value expressed by two 7-  
bit bytes “aa” and “bbH” would be aa x 128 + bb.  
*
*
In the case of signed (+/-) data, 00H = -64, 40H = +/-0, and 7FH = +63; i.e., a  
value 64 less than the decimal value shown in the above table is used. In the  
case of a two-byte value, 00 00H = -8192, 40 00 = +/-0, and 7F 7F = +8191. For  
example, a value of “aa” and “bbH” would have a decimal expression of aa  
bbH - 40 00H = aa x 128 + bb - 64 x 128.  
In the case of data indicated as “use nibble data,” hexadecimal expression in 4-  
bit units is used. A nibble-expressed value of the two bytes 0a and 0bH would  
have a value of a x 16 + b.  
<Example1>  
What is the decimal expression of 5AH?  
From the preceding table, 5AH = 90.  
<Example2>  
What is the decimal expression of the 7-bit hexadecimal value 12 34H?  
From the preceding table, 12H = 18, and 34H = 52.  
Thus, this is  
18 x 128 + 52 = 2356  
<Example3>  
What is the decimal expression of the nibble-expressed value 0A 03 09 0D?  
From the preceding table, 0AH = 10, 03H = 3, 09H = 9, and 0DH = 13.  
Thus, this is  
((10 x 16 + 3) x 16 + 9) x 16 + 13 = 41885
