Introduction

1

Congratulations on your purchase of M-Audio KeyStudio 49i: a 49-key full-size, velocity sensitive USB keyboard, digital piano, audio
interface, and software package, designed for easy integration with your PC or Macintosh computer. KeyStudio 49i is ideal for a
multitude of music creation applications.

KeyStudio 49i is a USB keyboard controller and standalone digital piano. It contains Octave shift buttons, Modulation and Pitch
Bend wheels, and a Piano Volume knob, all of which can be re-assigned to control different MIDI functions. KeyStudio 49i is also a
computer audio interface featuring XLR microphone, 1/4” instrument, and RCA inputs, as well as two 1/4” outputs.

KeyStudio 49i functions as a class-compliant device. This means your computer will recognize the keyboard without the need
to install additional drivers. This gives immediate access to all audio inputs and outputs as well as to the built-in MIDI interface.
However, as you become more familiar with KeyStudio 49i, you may wish to take advantage of this product’s additional professional
features by installing the KeyStudio 49i drivers.

Installing these drivers in Windows improves audio performance by reducing the time it takes for MIDI input (when using software
synthesizers) or audio input signals to appear as audio at your computer’s outputs. In Windows, additional benefits from driver
installation include: using your new keyboard with more than one application at the same time (multi-client), sending large SysEx
messages, or using your KeyStudio 49i with Pro Tools M-Powered recording software or the included GM Module software.

On a Macintosh computer, installing the M-Audio drivers enables you to use your KeyStudio 49i with Pro Tools M-Powered recording
software.

Information on driver installation can be found in the “Connecting KeyStudio 49i to a Computer” chapter of this User Guide.

Top Panel Descriptions

1. Modulation Wheel (Modulation): This is an assignable controller with a default of controlling vibrato or tremolo
effects assigned to the instrument you are currently playing. This type of real-time controller was originally introduced
on electronic keyboards to give the performer options such as adding vibrato, just like players of acoustic instruments
do. If you are using your keyboard as a MIDI controller, the Modulation wheel transmits MIDI modulation (MIDI CC 01)
messages as it is moved. Some external MIDI devices may not respond to modulation messages, and not all instruments
respond to modulation data sent from the Modulation wheel. Check the MIDI implementation charts provided with your
other MIDI equipment or software for modulation details. Details on how to change the function of this wheel can be
found in the “Advanced Features in Edit Mode” section.

2. Headphone Outputs (Phones): These two output jacks accept standard 1/4” TRS headphone plugs, and are rated to
accept headphones in a broad range of impedances, between 32 and 600 ohms.

3. Pitch Bend Wheel (Pitch Bend): The Pitch Bend wheel is used to bend the pitch of a note up or down. This enables
you to play phrases not normally associated with keyboard playing, including guitar-style riffs. If you are using your
keyboard as a MIDI controller, the Pitch Bend wheel transmits MIDI pitch bend messages as it is moved. Some external
MIDI devices may not respond to pitch bend messages. Check the MIDI implementation charts provided with your other
MIDI equipment or software for pitch bend details.

4. Octave < > Buttons (Octave): By default, these buttons apply octave shift to the notes played on the keyboard.
Pressing the Octave > button (right) will shift the notes played on the keyboard up by one octave. When octave shift is
active (i.e. after pressing this button) the LED above this button will light. Pressing the Octave < button (left) will shift the
notes played on the keyboard down by one octave. Pressing both Octave buttons together will restore the default octave
(Octave shift = 0). Any lit LEDs will go out and the keyboard will now transmit MIDI notes that are not octave-shifted.

The Octave buttons can also be assigned to send different MIDI data. This is explained in the “Advanced Features in Edit

Mode” section.

KeyStudio 49i User Guide

5. Edit Mode Button (Edit Mode): When this button is pressed, the keyboard will enter “Edit Mode.” While in Edit Mode,
the keys on the keyboard no longer send MIDI notes, and instead are used to select advanced functions and enter data.
See the “Advanced Features in Edit Mode” section for more information on this topic.

6. Master Volume Fader (Master Vol.): The Master Volume fader controls the main audio volume output.

7. Microphone Gain Knob (Mic. Gain): The signal (green) LED illuminates when incoming audio signal is greater than

-20dB. The peak (red) LED illuminates when incoming audio signal is greater than -1dB.

8. Instrument Gain Knob (Inst. Gain): The signal (green) LED illuminates when incoming audio signal is greater than

-20dB. The peak (red) LED illuminates when incoming audio signal is greater than -1dB.”

9. Mono Button (Mono): This is an analog button that sums the Microphone and Instrument inputs. When active, input
signals will be routed to both, the left and the right side of your stereo speakers or headphones, making them appear
centered in the stereo panorama.

When recording while the Mono Button is active, signals from the Microphone Input and Instrument Input will be merged

and recorded to both, the left and the right side of a stereo track in your recording software. If signals are entering the
keyboard through the Aux inputs or if you’re playing the built-in Piano sound while recording, then all sounds will be
merged and recorded to the same audio track.

This makes it easy to record an entire performance to a stereo track by the push of a button.

Note: The Mono button does not affect signals from the Aux Inputs or the the build-in Piano sound.

10. Direct Monitor Knob (Direct Monitor): The Direct Monitor knob controls the amount of audio input signal flowing
directly to the 1/4” audio outputs.

11. Piano Reset Button (Piano Reset): The Piano Reset button sends “All Notes Off” and “Reset All Controllers” MIDI
messages on MIDI channel 1. This button restores basic piano and keyboard controller functions, including resetting the
Modulation wheel, Piano Volume Knob, and Sustain Pedal to their default settings.

12. Piano Volume Knob (Piano Vol.): This is an assignable controller with a default of controlling the volume of the piano
sound flowing to the 1/4” audio outputs. Details on how to change the function of this knob can be found in the “Knob
Assign Key” section of the “Advanced Features in Edit Mode” section of this User Guide.

13. Reverb On/Off Button (Reverb On/Off): This button engages the internal reverb effect of KeyStudio 49i. The reverb
depth can be controlled via MIDI CC commands. See the “Advanced Features in Edit Mode” chapter of this User Guide
for more information on this.

Rear Panel Descriptions:

14. 1/4” Audio Outputs (Output R—L (Mono)): These are unbalanced tip-sleeve (TS) audio outputs for the piano sound,
signal from all inputs, and audio signal coming from your computer. If you are connecting to a mono (1 channel) device or
amplifier, use the left 1/4” output.

15. Auxiliary RCA Inputs (Aux Input R—L): These inputs mix with the XLR and 1/4” inputs, and also send their signal to
the audio outputs. These inputs can receive signal from a variety of sources including mixers, stereo receivers, and other
external sound producing equipment.

16. 1/4” Instrument Input (Instrument): This tip-sleeve (TS) unbalanced connector enables you to plug in an instrument,
such as an electric guitar or bass.

| 8

17. XLR Microphone Audio Input (Microphone): This input accepts a dynamic microphone connected via a standard
three-pin balanced XLR cable.

18. Sustain Pedal Jack (Sustain): You can plug any polarity foot pedal (not included) into the Sustain Pedal jack on your
KeyStudio 49i. The keyboard will automatically detect the correct polarity when powering up. If you want to reverse the
polarity, just make sure the pedal is pressed when you switch on your keyboard. The sustain foot pedal is normally used
for sustaining the sound you are playing without having to keep your hands on the keyboard, just like a piano.

19. MIDI Out Jack (MIDI Out): Your new MIDI controller can connect to optional external MIDI devices such as
synthesizers or sound modules. By default, MIDI data created by KeyStudio 49i is sent to this MIDI output port. However,
it is possible to configure KeyStudio to act as a USB to MIDI interface, allowing MIDI data from your computer to be sent
to this port. Please see section “MIDI Out Mode Key” on page 26 for more information.

20. USB Port: This enables you to connect to an available USB port on your computer using the USB cable provided.

21. DC Power Supply Port (9V DC): Connect a 9V DC >500mA center-positive power supply (sold separately) to this jack
when using KeyStudio 49i in standalone mode.

22. On/Off Switch: This On/Off switch turns KeyStudio 49i on and off.

23. Kensington® Security Slot: This slot is compatible with Kensington® security cables to protect your device from theft.

Audio Inputs

A dynamic microphone can be connected to the XLR input located on the rear panel, and an instrument such as a guitar or bass can
be connected to the 1/4” input jack, also located on the rear panel. Each of these two inputs has an independent preamp featuring a
dedicated gain control knob, and level and clip LEDs. Two analog RCA inputs are also located on the back panel. Signal from these
inputs is mixed with the Microphone and Instrument inputs before being routed through the USB connection to a connected Mac
or PC.

Audio Outputs

Connect the two analog 1/4” outputs (located on the rear panel of the KeyStudio) to powered monitors, an amplifier, or a mixer. You
may also monitor through headphones by connecting one or two sets of headphones to the 1/4” stereo headphone outputs, located
on the front panel.

MIDI Connections

In addition to the USB MIDI connection between KeyStudio 49i and your computer, you can connect the MIDI output of the
KeyStudio 49i to an external MIDI device’s MIDI input. This enables you to control an external synthesizer or sound module via your
computer, using the KeyStudio as a USB to MIDI interface, or as a standalone MIDI controller keyboard.

Other Connections

A sustain pedal can be connected to the 1/4” Sustain pedal jack on the back of KeyStudio.

KeyStudio 49i and the M-Audio GM Module Software

The M-Audio GM Module User Interface

Note: Installation instructions for the M-Audio GM Module software can be found in the printed Quick Start Guide included
with your KeyStudio 49i. The GM Module software requires the KeyStudio 49i hardware to be connected. Additionally,
Windows users will need to install the KeyStudio 49i drivers for the GM Module software to launch.

Overview

M-Audio GM Module is a 16-channel, multi-timbral General MIDI sound player. The GM Module software provides 128 instruments
(0-127). It receives MIDI messages from your KeyStudio 49i USB keyboard, and sends audio signal out of the KeyStudio audio
outputs.

Both the standalone and the plug-in versions of the software also contain a GM standard drum and percussion kit on channel 10.
Its polyphony and the number of instances that can be run at the same time in plug-in mode are limited only by your computer’s
performance.

The following is an explanation of the technical terms used in the previous paragraph. Understanding these terms will not only help to
get the most out of M-Audio GM Module, but will also be useful on your path as an electronic musician.

MIDI

MIDI is an abbreviation for Musical Instrument Digital Interface. MIDI in itself is a means of digital communication– no sound is
transmitted over a MIDI connection, but only a series of digital messages that tell a connected sound generator (like the M-Audio
GM Module) what to do. For example, if you hit the middle C on the KeyStudio keyboard, the keyboard will send a “Note On”
message, together with information about the pitch (middle C) and how hard or fast you hit the note (Velocity). The connected
sound generator will in turn play the sound for the middle C. If you let go of middle C, the KeyStudio keyboard will send a “Note Off”
message for the same note and the sound generator will stop playing. All this happens very fast and you usually don’t have to think
about it, but it’s good to know.

When MIDI was invented, a number of additional rules and specifications were defined. Some of them are directly responsible for
the way the M-Audio GM Module looks and functions:
