Installation and Setup
1. Connect the KeyStudio 25 keyboard.
The KeyStudio 25 USB keyboard is class-compliant. This means that you may simply connect the KeyStudio 25 keyboard to your
Windows XP, Windows Vista or Mac OS X computer using the provided USB cable and switch the keyboard on. No additional
installation or drivers are required.
NOTE: Windows users who would like to take advantage of the more advanced features of KeyStudio 25,
such as using the keyboard with more than one application at the same time (multi-client), should install the
optional M-Audio KeyStudio 25 drivers. These drivers can be found by going to the Support > Drivers page at
www.m-audio.com.
Advanced installation instructions for Windows users (optional):
1. If you have already connected the KeyStudio 25 keyboard to your computer, disconnect it before beginning the installation.
2. Download the most recent KeyStudio 25 drivers by going to the Support > Drivers page at www.m-audio.com. This ensures
that you have the newest drivers available. Double-click the le once it has nished downloading.
3. Follow the driver installer’s on-screen direction prompts.
4. At various points in this installation process, you may be notied that the driver being installed has not passed Windows
Logo Testing, or asked whether the program you wish to run is a trusted application. Click “Continue Anyway” or “Install” to
proceed with installation.
5. Once the installer has completed, click “Finish.”
6. Attach KeyStudio 25 to an available USB port using the cable provided. Make sure the power switch on the back of the
keyboard is in the “on” position. If you are using Windows Vista, your KeyStudio 25 installation is now complete. If you are
using Windows XP, proceed to steps 7-9.
7. Windows XP will identify the controller and will ask if you want to search the Internet for a driver. Select “No, not this time,”
and press “Next.”
8. Windows XP will display a Found New Hardware Wizard. Choose “Install the software automatically,” and click “Next.”
9. Click “Finish” once the Wizard has completed the installation.
Session KeyStudio 25 User Guide
2. Install the Session Music Creation Software.
1. Insert the M-Audio Session DVD-ROM into your computer’s DVD-ROM drive.
2. The computer will automatically display the install screen. If your computer fails to launch the installer, manually start it by
clicking on Start > My Computer* and then double-clicking Session.
3. Follow the software installer’s on-screen instructions.
NOTE: Session comes with a large library of loops and instrument samples for music creation, known as
Session Content. During the installation process, you will be asked if you would like to install the Session
Content on your hard drive. If you do not have 4 GB of disk space available, you may choose not to install
the Session Content, but you will then have to place the Session DVD in your DVD-ROM drive whenever you
run Session. Accessing Session’s content via DVD-ROM results in slightly slower computer performance. If
the required hard drive space is available, installing the Session Content on your computer’s hard drive is
recommended.
Please be aware that your Session software’s Factory Content Library may take as long as 30 minutes to
install. This behavior is normal. During the installation process, the installer displays helpful Session tutorial
information.

4. Click “Finish” once the installer has completed the installation.
*If you are using Windows Vista, “My Computer” will be labeled “Computer” in this step.

More Information on Configuring Session
To play back and record audio in Session, Session must communicate with your sound card.
On rst launch, Session attempts to choose the rst sound card containing both an audio
input and audio output, eectively making this connection automatically. If Session is not
able to select audio inputs and outputs automatically, it will open the Audio Hardware
dialog. If the process is successful (Session does not open the Audio Hardware dialog
automatically), but you cannot play back or record audio with Session, you’ll need to open
the Audio Hardware dialog by choosing Options>Audio Hardware.
The Audio Hardware dialog contains the following options:
ASIO/WDM Switch
This control switches the Audio Hardware dialog of Session between ASIO and WDM
mode. For best performance in Session, use ASIO mode. Consult the documentation for
your sound card to determine if it supports ASIO.
Output and Input Device Selectors
These controls set the Output Device (sound card) through which Session plays audio,
and the Input Device (sound card) from which Session records audio. It is recommended
that you select the same sound card for audio input and output.
Buffer Size Selector
This control sets the latency of Session. See the “About Latency” section found later in
this guide for additional information.
Session KeyStudio 25 User Guide
| 11
Use Low Latency Streaming Checkbox
When checked, Session attempts to open the selected audio interface in low latency mode (WDM Kernel Streaming). While most
sound cards should “open” in this mode, results vary widely based on the sound card in use. See the “About Latency” section of this
User Guide for further information on this.
OK Button
After making the desired settings, press the OK button to commit your changes and close the Audio Hardware dialog.
Cancel Button
Press the Cancel button to discard your changes and close the Audio Hardware dialog.
About Latency
Latency is loosely dened as the amount of time it takes for a sound made in Session to reach your speakers. For example, with
a high latency (Buer Size) setting, there will be a noticeable delay between the press of a key on KeyStudio 25, and the resultant
sound. Smaller Buer Size settings result in lower latency, but may not function well with slower systems. If you hear clicks and pops,
the Buer Size setting is too low. To adjust this setting of Session, open the Audio Hardware dialog (Options > Audio Hardware),
select the desired buer size from the Buer Size selector, and then click the OK button.
NOTE: Deselecting the “Low-Latency Streaming” checkbox may also reduce any clicks and pops in Session
audio. This setting is only available if WDM is selected as the driver type.
Upgrading your Sound Card
If you nd that your sound card is incapable of producing acceptable latency times, we recommend that you upgrade your sound
card. Visit www.m-audio.com for a selection of low latency ASIO audio interfaces for every purpose.
Using KeyStudio with GarageBand
The M-Audio Session software was created for use with Windows. However, the KeyStudio 25 hardware can be used with Macintosh
OS X computers as well. KeyStudio 25 integrates seamlessly with the GarageBand music production software which comes pre-installed
on many late-model Apple computers.
To use KeyStudio 25 with GarageBand:
1. Be sure KeyStudio is connected to your Mac OS X computer via the provided USB cable (See “Connect the KeyStudio 25
Keyboard.”)
2. Launch GarageBand.
3. Create a Software Instrument track by clicking Track > New Track > Software Instrument > Create, or select a pre-existing
Software Instrument track. The default instrument GarageBand selects is a Grand Piano.
When a Software Instrument is selected, clicking the button in the lower right corner of the GarageBand window will
open the Track Info screen. From this area, you can select which instrument you would like to play.
Provided your computer’s speakers are not muted or turned down, you will now hear sounds corresponding to notes you play
on KeyStudio.
