G Ab o u t th e PC-7 0
The Roland PC-70 is a MIDI keyboard controller. It does not contain any sound-generating
circuitry, since it is designed to provide for the convenient transmission of Program Change
and Bank Select messages, as well as a variety of other MIDI messages (such as reverb and
chorus information) to an external sound module. It is particularly suited for controlling
sound modules that comply with the GS Format. (Called simply “GS sound modules” in the
following.)
G W h a t is th e Ge n e ra l MIDI?
General MIDI is a set of recommendations which seeks to provide a way to go beyond the
limitations of proprietary designs, and standardize the MIDI capabilities of sound generating
devices. Sound generating devices and music files that meet the General MIDI standard bear
the General MIDI logo (
).
Music files bearing the General MIDI logo can be played back using any General MIDI sound
generating unit to produce essentially the same musical performance.
G W h a t is th e Ge n e ra l MIDI 2 ?
The upwardly compatible General MIDI 2 (
) recommendations pick up where the
original General MIDI left off, offering enhanced expressive capabilities, and even greater
compatibility.
Issues that were not covered by the original General MIDI recommendations, such as how
sounds are to be edited, and how effects should be handled, have now been precisely
defined. Moreover, the available sounds have been expanded.
General MIDI 2 compliant sound generators are capable of reliably playing back music files
that carry either the General MIDI or General MIDI 2 logo.
In some cases, the conventional form of General MIDI, which does not include the new
enhancements, is referred to as “General MIDI 1” as a way of distinguishing it from General
MIDI 2.
G W h a t is th e GS Fo rm a t?
The GS Format (
) is Roland’s set of specifications for standardizing the performance of
sound generating devices. In addition to including support for everything defined by the
General MIDI, the highly compatible GS Format additionally offers an expanded number of
sounds, provides for the editing of sounds, and spells out many details for a wide range of
extra features, including effects such as reverb and chorus. Designed with the future in mind,
the GS Format can readily include new sounds and support new hardware features when
they arrive.
Ab o u t th e So u n d s Co n ta in e d in a GS So u n d Mo d u le
A GS sound module contains 128 basic sounds (Capital Tones) and a number of Variation
Tones. The mapping for the Capital Tones is compatible with Level 1 of the General MIDI
System. Capital Tones are stored in Bank 0, while the Variations are stored in Banks 1
through 127. The selection of Variation Tones that are made available will be different
depending on the sound module. You should check the manual for any module you are
going to use, and familiarize yourself with the sound collection it contains.
7
Ab o u t th e Dru m Se ts Pro vid e d b y a GS So u n d Mo d u le
The Drum Channel (ch. 10) provides for the use of several Variation Sets in addition to the
basic Drum Set (Standard Set: PC #1). Drum Sets are selected using Program Change
messages. The types of Variation Sets that are made available will be different depending on
the sound module. Refer to the manual for the module you are using so you know what
kinds of drum sets it contains.
* If a Variation Tone or Variation Drum Set you have requested is not found in the GS module you are
using, the module may not sound at all, or an incorrect sound may be played.
G Ma in Fe a tu re s
Su p e rb Pla y a b ility a n d Ex p re ssive n e ss
Since this standard 49-key keyboard also provides response to velocity, it allows you to
express even the finest nuances. In addition, an Octave Shift feature allows you to
conveniently shift the soundable range up or down by an octave. Moreover, it is equipped
with a pitch/ modulation wheel, and provides a jack for connecting a damper pedal.
Co m p le te Ra n g e o f Co n tro l Fe a tu re s
Since the keyboard provides for sound selections that use combinations of Program Change
and Bank Select messages (value for CC 00 and CC 32), you can also select any of the
Variation Tones that may be available on a GS sound module.
In addition, a variety of continuous controllers (Control Changes) can be assigned to the data
entry slider. The slider can then be used for variable control over the desired parameter
(reverb or chorus depth, for example) on a GS sound module.
Viewing the contents of the LED display allows you to operate easily and precisely.
Ma k e s De sk To p Mu sic (DTM) Mo re En jo y a b le
The PC-70 is very compact, so it requires only a minimal amount of desktop space. The
keyboard is sure to become an invaluable part of any DTM setup, since it can be used for
real-time or step recording, as well as for practice while listening to “minus-one” playback.

Program Change/ Bank Select messages are used for changing Tones for an ordinary
instrument Part, and for changing Drum Sets for the Drum Part (GS: ch. 10).
Ch a n g in g So u n d s in a GS So u n d Mo d u le
To change Tones in a GS module, you need to send the Bank Select message (consists of the
values for Controller Numbers [CC] 00 and 32) together with the Program Number.
The value of Controller Number 00 (MSB) and that of Controller Number 32 (LSB) work
together as a pair to specify a Bank. The Program Number that comes immediately after
completes the switch to the desired sound.
On the PC-70, these three messages are always sent as one set:
•
•
•
Value of Controller Number 00 (MSB)

Ch a n g in g Dru m Se ts in a GS So u n d Mo d u le
The Drum Part (ch. 10) of a GS module does not respond to Bank Select messages. However,
if you try to send only a Program Change message from the PC-70, a Bank Select message
will end up being transmitted along with it anyway because the data for the last sound
specified will have been retained in memory. For this reason, you should always send a
value of 0 for Controller Numbers 00 and 32 first, then send the Program Number in order to
make sure you obtain the Drum Set you need.

The following functions can be assigned to the DATA ENTRY slider:
Function nameDescription
Channel Aftertouch Alters notes currently being played
VelocityChanges dynamics
Reverb Send Level (CC 91)Sets the depth of Reverb
Chorus Send Level (CC 93)Sets the depth of Chorus
Volume (CC 07)Sets the volume level of the Part
Panpot (CC 10)Sets sound position (localization in the stereo sound field)
CC 00 to 127Depends on the selected Controller Number
* Since a slider control accesses digital information, it might not produce any noticeable change in the
value if moved by only a small amount. If this happens, move the slider up and down once, then set the
value.

The keyboard on the PC-70 cannot transmit Channel Aftertouch messages. However, such
messages can be transmitted by assigning the Channel Aftertouch function to the DATA
ENTRY slider on the PC-70.
Channel Aftertouch is a function that lets you alter notes (that have already been played) by
applying additional pressure on the keys. The PC-70 can create this Aftertouch effect—
simply move the DATA ENTRY slider after Aftertouch has been assigned to it.

Aftertouch
[Procedure]
1 . Set the MIDI transmit channel to match that of the desired Part.
2 . Press MIDI/SELECT [3] (LED will show “SEL”).
3 . Press the F3 white key (AFTER TOUCH) [7].
4 . Press MIDI/SELECT [3] again to confirm your selection. Now, when you move the
DATA ENTRY slider, Channel Aftertouch messages (with a value reflecting the
slider’s position) will be transmitted.
* A GS sound module will not respond to Aftertouch messages while it remains set at its factory
defaults. For details, refer to the owner’s manual for the sound module you are using. Computer users
should consult the owner’s manual for their software, since it may be possible to select a response for
Channel Aftertouch within the software.

By assigning a controller number to the DATA ENTRY slider, the slider can be used for
controlling a wide range of features on your sound module.
Any controller numbered from 0 to 95 (Continuous Controllers) can be assigned. Since the
PC-70 isn’t equipped with a display which allows you to monitor data when transmitting it,
it is not suited for operations which involve Registered and Non-Registered Parameter
Numbers.

Tro u b le sh o o tin g
Q: The unit cannot be switched on; or it doesn’t work at all.
A: Check if you are using the attached AC adaptor. Use only the attached adaptor—using
any other adaptor may result in damage, malfunction or electric shock.
Q: The sound module does not respond to the movement of the DATA ENTRY slider.
A: Check if the correct function is assigned to the DATA ENTRY slider. Also, note that the
module will sometimes not respond if the slider is moved only slightly. If you are
unsure, pull the slider all the way down first and then set it to the desired position.
Q: The sound you have requested cannot be selected.
A: Some GS modules, such as those in the Sound Canvas series, have a switch which allows
you to turn on or off the reception of Program Change messages and/ or Bank Select
messages. Be sure this switch is turned ON.
A: Could the sound module have received a GM System On message (the message that
orders a module to function as a General MIDI sound module) before you sent Bank
Select messages? Since Bank Selects are not recognized in the General MIDI System Level
1 specifications, the module will ignore them if it is currently behaving as a General
MIDI device. To correct this situation, send a GS Reset message (which retrieves the GS
default settings), or simply switch the module off, then on again.
*
The PC-70 cannot transmit GS Reset messages.
A: When specifying the change in sound, did you supply the complete set of values (values
for CC 00/ CC 32 and Program Number)? When a change in sound is made using the PC-
70, the complete set of three values (value for CC 00 and CC 32, then the Program
number) is transmitted, even if only the Program Number has been specified. Note also
that the values for a sound selection remain stored in memory until the next sound has
been successfully selected. So, if even one out of the complete set of three values is
mistakenly not supplied, part of the previous values could be sent along with the newly
specified ones. As a result, you might not obtain the sound you hoped for.
A: Does your computer music application use Program Numbers 0 to 127 for sound
selection? Since the PC-70 uses numbers 1 to 128, you may need to add one to the
number being selected to obtain the correct sound.
Q: The GS module does not respond to Aftertouch messages.
A: A GS sound module will not respond to Aftertouch messages when it’s in its default
mode. Therefore, you need to set the Aftertouch parameters using Exclusive messages.
(Refer to the MIDI Implementation for the sound module in question.) If using a
computer-based system, you may be able to easily make the required settings using the
software.
