Getting Started with Music Creation Software
7
If you are new to MIDI (Musical Instrument Digital Interface), you may nd it challenging to understand why sounds have not simply
been included in the keyboard. You will find that using a software-based sound source and recording system allows for access
to an extremely large array of high quality sounds, a large graphic user interface, and freedom to work with many music creation
applications. A basic understanding of MIDI will enable you to take advantage of its wealth of creative possibilities.
Pressing a KeyStudio key causes the keyboard to send out MIDI (Musical Instrument Digital Interface) data. MIDI data just gives
instructions on how a sound should play. These instructions dictate parameters such as what note to play, when to play it, how loud
to play it, and which sound to use.
When using a virtual (software) instrument within your recording software, data from the KeyStudio keyboard is sent to the
sequencer software, routed to a virtual instrument, and sent to an audio output. This process turns MIDI data into audible sounds.
For this, you must congure your music software to read MIDI data being sent from KeyStudio, and play the sound back accordingly.
In many music applications, much of this process is automated. GarageBand, for example, only requires you to highlight a Software
Instrument track in order to be able to hear what you are playing on your KeyStudio keyboard. Provided your computer has built-in
speakers, or you have external speakers connected (and these speakers are not muted or turned down), you should hear sounds
corresponding to notes you play on KeyStudio. See the documentation associated with any MIDI-compatible music software you are
using for more information.
Key Names
The letters printed above the white keys stand for the names of the musical notes the keys represent. The number next to each
letter marks the octave each key belongs to. (More information on octaves can be found in the following section.) Black keys are
“semitones” to their adjacent white keys and don’t have a dedicated letter. A semitone represents the distance in pitch from one note
to its immediate neighbor.
Black keys usually have the same name as the next higher or lower white key, but have an additional sharp symbol (# – semitone
higher than the letter indicates), or at symbol (b – semitone lower than the letter indicates) attached to them. For example, the name
of the black key to the right of C3 is C#3 (C-sharp 3), but it can also be called Db3 (D-at 3), since it is also adjacent to the D key
on its right. In other words, black keys have two valid names, depending on the context of the musical notation they are part of.
Octave Buttons
An octave contains 12 notes, and each octave is marked out clearly on your KeyStudio keyboard by black and white sections starting
on C. Each octave is given a number.
KeyStudio is able to shift the pitch of its keys up or down by one or more octaves. When the keyboard’s octaves are not shifted
(octave shift set to zero), the lights above both the Octave “<” and Octave “>” buttons will be lit. The default octave shift designation
is zero and will be the octave setting each time you power up the keyboard.
If you press the Octave “>” button once, the light above the Octave “<” button will go out, indicating the keyboard is now playing
an octave higher. If you press the Octave “>” button again, the keyboard will be shifted up two octaves. It is possible to shift the
keyboard up a total of four octaves using the Octave “>” button. To shift the octave down, press the Octave “<” button in the same
manner: pressing once for one octave, twice for two octaves, and three times for three octaves. It is possible to shift the keyboard
down a total of three octaves.
To return the keyboard’s octave shift to zero, press both the Octave “<” and “>” buttons at the same time. Both LEDs will light,
indicating that the octave shift has returned to zero. In summary, when the Octave buttons are set to control octave shift (default), if
the light is only lit above the Octave “>” button, the octave is shifted up. If the light is only lit above the Octave “<” button, the octave
is shifted down.

Pitch Bend Wheel
As the name indicates, the Pitch Bend wheel is usually used to bend the notes played on the keyboard up or down. This allows you
to play phrases not normally associated with keyboard playing, including guitar-style riffs. Your sound source determines how far you
can bend the note. The usual setting is two semitones but can be up to two octaves up or down.
Modulation Wheel
The Modulation wheel is typically used for modulation of the sound you are playing. This real-time controller was originally introduced
on electronic keyboard instruments to give the performer options such as adding vibrato, just like players of acoustic instruments do.
KeyStudio’s Modulation wheel is assignable to control many possible parameters. (See chapter “Advanced KeyStudio Features in
Edit Mode” for more information on this.)
Volume Slider
The Volume slider can send MIDI messages that control the volume of the notes you are playing. The Volume slider can also be
assigned to control different parameters such as pan (balance), attack, reverb, and chorus. (See chapter “Advanced KeyStudio
Features in Edit Mode” for more information on this.)
Sustain Pedal Jack
You can connect a momentary-contact foot pedal (not included) to the Sustain jack on the back of your M-Audio keyboard. The
keyboard will automatically detect the correct polarity when powering up. If you want to reverse the polarity, simply press the pedal
when you switch on your keyboard.
The foot pedal is normally used for sustaining the sound you are playing without having to keep your fingers pressing down the keys.
This is similar to an acoustic piano’s sustain pedal function.
Advanced Features in Edit Mode
8
The button to the left of the keys labeled “Edit Mode” is used to access additional advanced functions of the keyboard. When this
button is pressed, the keyboard will enter Edit mode and the keys on the keyboard can be used to select functions and enter data.
The light above the Edit Mode button indicates whether or not the keyboard is in Edit mode. When in Edit mode, the black keys on
the keyboard are used for selecting functions, while the white keys are used for data entry and channel selection.
Your keyboard will exit Edit mode as soon as either a function is selected or the CANCEL or ENTER key is pressed. The light above
the Edit Mode button will then turn off and the keyboard can then be used to play notes again. Some functions do not require any
additional data entry. When these functions are selected, the keyboard will automatically exit Edit mode and return to Performance
mode.
NOTE: Not every music application can process all types of MIDI messages KeyStudio is capable of sending. Please consult your
software’s documentation for information on what messages it can accept.

Advanced Functions in Edit Mode
| 9
Octave Buttons Options
The Octave “< ” and “>” buttons can be assigned to control one of six possible MIDI functions:
• Octave Shift• Program Change• Bank MSB
• Transpose• Bank LSB• MIDI Channel Change
In the diagram above, the rst six black keys are labeled “DATA = OCTAVE, DATA = TRANSPOSE, DATA = PROGRAM, DATA
= BANK LSB, DATA = BANK MSB, and DATA = CHANNEL.” These keys are used to select the desired alternate function of the
Octave buttons.
To select an alternate function:
1. Press the Edit Mode button.
2. Press the black key that represents the function you want to assign to the Octave buttons. KeyStudio will exit Edit
mode as soon as you push one of these keys.
PLEASE NOTE: Some of the functions that the Octave buttons can be used for cannot send out a value less than zero.
When used to control these functions, both lights above the buttons will remain on, regardless of the current setting of
that function.
The available functions of the octave buttons are:
Octave Shift
The Octave “< ” and “>” buttons control octave shift by default. However, if these keys have been programmed to control
another function, you may wish to re-assign them to control octave shift once again.
To assign the Octave “<” and “ >” buttons to control octave shift:
1. Press the Edit Mode button.
2. Press the black key above C1 (C#1), representing DATA = OCTAVE. KeyStudio will exit Edit mode as soon as
C#1 has been pressed.
KeyStudio User Guide
| 10
Another method of shifting KeyStudio’s octaves is with the use of the black keys labeled OCTAVE “+,” “-,” and “0” on the
Advanced Functions in Edit Mode diagram. This octave shift method can be useful when the Octave buttons have been
reassigned to control another MIDI function.
1. Press the Edit Mode button.
2. Press the black key below B2 (Bb2). In Edit mode, this key functions as “OCTAVE +,” shifting the keyboard up one
octave. It is possible to shift the keyboard up a total of four octaves.
3. Press the black key above F2 (F#2). In Edit mode, this key functions as “OCTAVE -,” shifting the keyboard down one
octave. It is possible to shift the keyboard down a total of three octaves.
4. Press the black key above G2 (G#2). In Edit mode, this key functions as “OCTAVE 0” to reset the octave shift to zero.
5. When you have chosen your octave shift, either press C5 representing “ENTER,” or press the Edit Mode button to exit
Edit mode.
Transpose
In some cases it is useful to increase or decrease the transmitted pitch by a small number of semitones rather than a whole
octave. For example, you may be playing a song with a singer and the singer is having trouble hitting the high notes. In this
case, you can try reducing the pitch by one or more semitones. This is achieved using a function called “Transpose.”
Transpose works similar to octave shift, except the shift is not limited to multiples of 12 semi-tones. As with octave shift, there
are two ways of transposing the keyboard. When in Edit mode, you can assign the Octave “<” and “>” buttons to control the
transpose feature. Alternatively, you can use the black keys F#3, G#3, and Bb3 to shift the transposition. These black keys
represent “TRANSPOSE -,” “TRANSPOSE 0” and “TRANSPOSE +” respectively.
To assign the Octave “<” and “ >” buttons to transpose:
1. Press the Edit Mode button.
2. Press the black key above D1 (D#1), representing “DATA = TRANSPOSE.” KeyStudio will exit Edit mode as soon
as D#1 has been pressed.
When the Octave buttons are assigned to transpose the keyboard, the lights above the buttons indicate the direction of the
transposition. To return the keyboard’s transpose shift to zero, press both the Octave “<” and “>” buttons at the same time.
Channel
MIDI data from the keyboard can be sent on any of 16 MIDI channels. KeyStudio’s default is to transmit MIDI data on channel 1.
However, certain MIDI performance or recording scenarios may require the keyboard to send data on a different channel. You
can change the channel on which data is sent using the following method:
1. Press the Edit Mode button.
2. Press one of the 16 channel keys from D1 to E3, whichever one represents the channel you need. KeyStudio will exit
Edit mode as soon as a channel key has been pressed.
For example, if a device species that you need to send data on channel 10, press the Edit Mode button, and then F2 to select
channel 10. This channel is usually dedicated to drum sounds when working with GM compatible synthesizers and sound
modules.
The channel can also be assigned to the Octave “<” and “>” buttons by pressing the Edit Mode button and then C#2. This
will allow the Octave “<” and “>” buttons to increment or decrement through the channels. When channel 16 is reached
and “>” is pressed, channel 1 will be selected. If the Octave “<” and “>” buttons are assigned to vary the channel, the lights
above the buttons will not change, since it is not possible to have a channel with a negative value. Pressing both the “<” and
“>” buttons together will recall KeyStudio’s default, channel 1.

Program Change
Program changes are used to change the instrument or voice you are controlling with your KeyStudio. Program change
messages can be benecial when using the KeyStudio keyboard to control MIDI sound modules or synthesizers. Some music
software applications support these messages, however, others do not. Check your software’s User Guide to nd out if it can
process program change messages.
In this example, we will demonstrate how to change the instrument on a General MIDI sound module to a cello sound. To do
this we need to send a program change of 42, which will select a cello sound from the General MIDI Instruments standard list
(see Appendix A). There are two methods to send the program change:
1) Increment/Decrement Program Change:
1. Press the Edit Mode button.
2. Press the black key above F1 (F#1). Now the Octave “<” and “>” buttons can be used to change the program.
2) Quick Select Program Change
1. Press the Edit Mode button.
2. Press the black key above F4 (F#4), representing “program.”
3. Press keys D4, then B3, then C5. This enters the combination: “4,” “2,” “ENTER.”
Now the keyboard is set to play the GM cello sound 42 (from the General MIDI Instruments standard list). The full list of
General MIDI program numbers is given in Appendix A at the end of this manual.
Method 1 is useful if you want to cycle through different instruments for the purpose of comparing and choosing which sound
works best in your song. Method 2 is more useful if you want to select a specific sound patch, as is the case here.
If the Octave “<” and “>” buttons have been assigned to control the program number (Method 1), the lights above the
buttons will not change, since it is not possible to have a program with a negative value. Pressing both the “<” and “>”
buttons together will recall Program 0, which selects the rst sound patch on any synthesizer capable of processing MIDI
program changes.
Bank LSB and Bank MSB
Program changes are the most commonly used messages to change instruments and voices. However, the number of
instruments accessible using only the program change MIDI command is limited to 128. Since some devices have more than
128 voices, they require a method to organize their large number of sounds into banks. These devices then access the sounds
within these banks by using program change messages. See chapter “MIDI Messages Explained” for additional information.
Generally, these devices use Bank LSB (Least Signicant Byte) and Bank MSB (Most Signicant Byte) change messages.
KeyStudio can send these bank change messages in two possible ways:
1) Incremental/Decremental Bank LSB and Bank MSB Change:
1. Press the Edit Mode button.
2. Press the black key above G1 (G#1) or Bb1 (A#1), representing Bank LSB or Bank MSB respectively. Now the
Octave “<” and “>” buttons can be used to change Bank LSB or Bank MSB.
2) Using the Quick Select Method:
1. Press the Edit Mode button.
2. Press the black key above G4 (G#4), or Bb4 (A#4), representing Bank LSB or Bank MSB respectively.
3. Press the white keys associated with the bank number you wish to select, and then press C5 (Enter). For example,
pressing the C4 (the number 3), A3 (the number 1), and C5 (Enter) keys in this step selects bank 31.
KeyStudio User Guide
As with Program changes, if the Octave “<” and “>” buttons are selected to vary the Bank LSB or MSB number (Method 1),
the lights above the buttons will not change, since it is not possible to have a Bank with a negative value. Pressing both the
“<” and “>” buttons together will recall Bank 0.
Bank change messages must be followed by a program change message in order to recall a sound. Bank change messages
by themselves do not activate a sound, but only locate and access a predefined location of a set (bank) of 128 sounds.
PLEASE NOTE: Each time the keyboard is turned off, optional MIDI parameters assigned to the Octave buttons will be lost.
When the keyboard is powered up, the Octave buttons will default to controlling octave shift.

Other Assignable Controllers
9
The Modulation Wheel
It is possible to assign different MIDI controller numbers to the Modulation wheel. These parameters are called MIDI continuous
controllers. There are 132 (counting from and including zero to 131) MIDI continuous controllers (MIDI CC’s). For these controller
values to have any effect on the sound, the receiving software or device has to be able to read and respond to these MIDI controller
messages. KeyStudio accepts controller numbers 0-131. Numbers beyond 127 are a proprietary method M-Audio uses to simplify
the transmission of certain, otherwise more complicated multi-part MIDI messages. A full list of controller values is given at the back
of this manual in Appendix B.
Some useful MIDI CC’s are:
< 01 Modulation
< 07 Volume
< 10 Pan (balance)
< 05 Portamento
To assign a MIDI controller message to the Modulation wheel:
1. Press the Edit Mode button.
2. Press the black key above C4 (C#4), representing “WHEEL ASSIGN.”
3. Use the Numerical Data Entry keys G3 – B4 to enter the number of the MIDI controller you want to assign to the
Modulation wheel.
4. Press the ENTER key (C5).
5. Move the Modulation wheel upwards to increase the value of the MIDI message sent.
If you make an error while entering the numerical data value, you can press the CANCEL key (C1) to exit Edit mode without
changing the MIDI CC assigned to the Modulation wheel.
KeyStudio User Guide
As an example, let’s assign effect number 10 to the Modulation wheel. This means the Modulation wheel will control Pan (or
balance). To do this:
1. Press the Edit Mode button.
2. Press the black key above C4 (C#4), representing “WHEEL ASSIGN.”
3. Press A3 to enter “1.”
4. Press G3 to enter “0” so you have entered “10.”
5. Press C5 for “ENTER.”
| 13
The Volume Slider
As with the Modulation wheel, the Volume slider can also be assigned to any of the 132 controllers (0-131) shown at the back of this
manual.
To assign the Volume slider to a certain MIDI parameter:
1. Press the Edit Mode button.
2. Press the black key above D4 (D#4), representing “SLIDER ASSIGN.”
3. Use the Numerical Data Entry keys G3 – B4 to enter the number of the controller value you want to assign to the
Volume slider.
4. Press the ENTER key (C5).
If you make an error while entering the numerical data value, you can press the CANCEL key (C1) to exit Edit mode without
changing the MIDI CC assigned to the Volume slider.
PLEASE NOTE: Each time the keyboard is turned off, optional MIDI parameters assigned to the Volume slider or
Modulation wheel will be lost. Each time the keyboard is powered up, the Volume slider will default to being assigned to
Volume (MIDI CC 07), and the Modulation wheel will default to being assigned to modulation (MIDI CC 01).

MIDI Messages In-Depth
10
Program & Bank Changes
When the MIDI standard was rst established, it enabled the user to access only 128 different sounds using program change
messages (0-127). As MIDI devices grew to be more sophisticated and contain more sounds, bank change messages were included
in an updated MIDI specication to allow for more than 128 sounds to be accessed.
The language MIDI uses to communicate between musical instruments only allows for program change commands 0-127, for a
total of 128 possible programs (127 programs + program “0” = 128 programs total). Because of inherent limitations of the MIDI
communication protocol, the number of directly accessible programs (using program change messages) cannot easily be expanded
beyond 128. Thus, a system of banks, with 128 sounds in each, has been created that enables manufacturers to overcome the 128-
sound MIDI limit.
128 banks with 128 sounds in each bank is the basic
principle used to expand the number of accessible
sounds. However, to avoid reaching the new limit of
the resulting 16,384 possible sounds (128 banks
x 128 programs) accessible using a bank change
combined with a program change, another layer
of banks was added. The result is a system of 128
banks that can contain 128 sub-banks in each
of them, which, in turn, can contain 128 sounds
(programs) within them.
Bank change messages are useful when calling
up sounds from a large library that may exist in a
particular sound module or software synth. For
example devices that are built with Roland’s GS
specication or Yamaha’s XG specication require
you to specify a bank change in order to access the
extra voices and effects that these devices provide.
MIDI CC 0 is the bank select MSB (Most Signicant
Byte) message. This MIDI message is 7-bit in size
and can be used to select any of 128 banks. This
message can be used in conjunction with MIDI CC
32 which is bank select LSB (Least Significant
Byte): a separate 7-bit message allowing additional
selection of any of another 128 sub-banks. The
combination of Bank MSB and LSB messages gives
a 14-bit message that can select any of a possible
16,384 banks. Each bank can in turn contain 128
possible sounds selected via a separate program
change MIDI message. This enables a user to
theoretically recall over two million programs directly,
using only MIDI commands. However, most devices
only use a few different banks, and allow you to
access them with either a Bank LSB message
or a Bank MSB message. Please consult your
synthesizer’s or software’s documentation for more
information on which type of bank change messages
it can process.

KeyStudio User Guide
You will nd many MIDI devices respond to program change commands and many are organized according to the GM listing. In
General MIDI devices, different sounds are organized in the same way from device to device. Piano sounds are in their particular
place, string sounds are in their place, drum sounds are in their place, and so on. All GM devices (both hardware and software
sound modules) are clearly labeled as such, so you know that their sounds are organized in the General MIDI structure. When a GM
device receives a MIDI program change, it calls up a type of sound that you expect from the GM sound set. All non-GM MIDI sound
modules call up unique sounds from their memory upon receiving MIDI program changes. Since the sounds in a non-GM device are
not arranged in a particular order, you need to take a look at the device itself to see which sound you want and at which location in
the memory it resides. Many VST instruments such as Native Instruments’ FM7 or the synth modules in Propellerhead Reason are
non-GM devices.
You can send program change, bank LSB and bank MSB messages directly from the KeyStudio keyboard. Please consult the
“Advanced KeyStudio Features in Edit Mode“ section of this User Guide for further details.

NRPN/RPNs
Non-registered parameter numbers (NRPN’s) are device-specic messages that enable you to control synths and sound modules
via MIDI. The MIDI specication denes open parameter numbers to allow manufacturers to specify their own controllers. The more
common of these are registered by the MIDI Manufacturer’s Association and are now part of the MIDI specication (hence the term
Registered Parameter Numbers – RPN’s). (See Appendix B) Each NRPN/RPN has an associated 2-byte number. The two bytes
allow for 128 values each. (An RPN or NRPN message is made up of two parts: the MSB and the LSB message. Both of these
messages together constitute an RPN or NRPN command.) This allows for 16,384 values in total.
MIDI controllers 98 and 99 represent the NRPN LSB and MSB respectively, while 100 and 101 represent the RPN LSB and
MSB messages (see the MIDI controllers list in Appendix B). To transmit an NRPN/RPN message, these LSB and MSB controller
messages are sent along with their user-specified values. A further controller message and value needs to be sent to specify the
(coarse or ne) value adjustment. This is specied by controller number 6 (data entry) for coarse adjustments or number 38 for ne
adjustments.
A list of NRPN’s is usually given in the user’s manual of any device that receives NRPN messages. It is always necessary that the
NRPN MSB and LSB be sent together. Both will be specied in the device’s manual.

Troubleshooting
11
KeyStudio has been tested in a wide range of systems and operating conditions. However, there are virtually limitless numbers of
operating scenarios, any of which could affect your system’s performance. Though this section cannot cover all possible situations
you may encounter, we would like to offer some suggestions for dealing with possible problems. If you are still not able to find the
answer you are looking for, please feel free to contact M-Audio technical support for further assistance.
Problem 1: My KeyStudio suddenly stopped working after having performed fine since installation.
Solution 1: Close any music applications you are using, switch KeyStudio off, and restart your computer. Once your computer
has completely restarted, switch KeyStudio back on.
Problem 2: I have connected a sustain pedal to my M-Audio keyboard, but its function is reversed.
Solution 2: The polarity of the sustain pedal is calculated by the keyboard when it is powered up. On power up, the sustain
pedal is assumed to be in the OFF position. If you want the sustain pedal to be off when it is not pressed, make sure the pedal
is not pressed when you power up. Also check to see if there is a polarity switch on your foot pedal. It is possible to use this
switch to change foot pedal polarity as well. Another way to reverse the sustain pedal’s polarity is to keep it pushed while
powering on your KeyStudio keyboard.
Problem 3: KeyStudio does not trigger sounds in my music software application.
Solution 3: Be sure KeyStudio is selected as the MIDI input device within your software.
Problem 4: I cannot locate the KeyStudio USB keyboard in my software’s MIDI devices dialog box.
Solution 4: KeyStudio requires a powered USB port. Try plugging KeyStudio into a different USB port or powered USB hub
connected to your computer.
Problem 5: My synthesizer always recalls the sound next to the program number that I have sent to it from KeyStudio.
For example, if I send a program change with the number 40 (Violin), my software loads sound number 41 (Viola).
Solution 5: Some General MIDI modules count their sound patches from 1 – 128 instead of 0-127. Both methods are
common. As a result, and depending on the sound module you use, there may be an offset of +/-1 between the sent program
change number and the recalled sound patch.
Problem 6: I am trying to use KeyStudio with two or more MIDI applications at the same time, but KeyStudio is only
being recognized by one application.
Solution 6: For multi-client support, it is necessary to install the latest M-Audio KeyStudio drivers for your computer’s
operating system.
To install the M-Audio KeyStudio drivers:
1. Make sure KeyStudio is not connected to your computer.
2. Download the latest KeyStudio drivers from the Support > Drivers page at www.m-audio.com. Once you have
saved the installer to your computer’s hard drive, run the installer and follow the onscreen instructions. The installer
will indicate when installation has finished. At that point, you may connect KeyStudio to your computer.
Problem 7: I am using KeyStudio with Windows XP, but cannot find it listed as a MIDI input device.
Solution 7: In Windows XP, if KeyStudio is being used as a class compliant device (this means using the device with the
drivers already built into the computer’s operating system), KeyStudio will be listed as “USB Audio Device.” For the device
to appear as “KeyStudio,” install the latest M-Audio KeyStudio drivers for your computer’s operating system. For details, see
Solution 6 above.

Useful MIDI-Specific Troubleshooting Features
12
KeyStudio has been designed to make working with MIDI on your computer as simple as possible. However, sometimes things can
go wrong. To counter this, there are two useful MIDI functions.
All Notes Off
Use this if you nd there are sustaining notes that you cannot stop. To send an “All Notes Off” MIDI message:
1. Press the Edit Mode button.
2. Press the black key above D3 (D# 3), representing “ALL NOTES OFF.”
3. Edit mode will exit, and there will no longer be any sustaining notes.
Reset All Controllers
If one or more of the loaded sound patches doesn’t sound as expected, then it may mean that a MIDI CC has applied an undesired
effect or other type of sound modulation to that voice. If you are unsure which MIDI controller to adjust to eliminate the effect,
you can send a “Reset All Controllers” MIDI message to set all controller values to their defaults. To send a Reset All Controllers
message:
1. Press the Edit Mode button.
2. Press the black key above C3 (C# 3), representing “RESET ALL CONTROLLERS.”
3. Edit mode will exit, and all controller values will be reset to their default values.

Appendix A - General MIDI Instruments
PLEASE NOTE: The following table lists all General MIDI patch names using numbers from 0 – 127. Be advised that some GM
modules count their sound patches from 1 – 128 instead. Both methods are common. As a result, and depending on the sound
module you use, there may be an offset of -1 between the sent program change number and the recalled sound patch.

KeyStudio User Guide
Appendix C - Additional RPN Messages
You may have noticed that although we have stated there are 128 MIDI controller messages (0 – 127), Appendix B shows 132
assignable controller messages. This is because messages 128 – 131 are a different type of MIDI message, dened in the MIDI
Specication as RPN messages. M-Audio has created four messages that are sent like MIDI CCs, but actually transmit a series of
RPN messages. This makes sending these complex multi-part messages as easy as sending a MIDI CC message. You can assign
these to the controls on your KeyStudio keyboard in exactly the same way as any other MIDI controller message. The RPN messages
control the following:
Controller NumberMIDI MessageUse
128Pitch Bend SensitivityAlters the range of a pitch bend message
129Master Tune (coarse)Adjusts the tuning of your sound module or synthesizer in large steps
130Master Tune (fine)Adjusts the tuning of your sound module or synthesizer in small steps
131Monophonic Aftertouch*Adds a vibrato effect
*Monophonic aftertouch is not an RPN message. However, it is an additional effect message defined in the General MIDI
specification and this is why we have included it in Appendix C.
