Congratulations on your purchase of JamLab. This document explains the JamLab’s control panel as well as the basics of GT Player Express. It
also explains how to use the M-Audio ProSessions drum loops and MP3 songs with GT Player Express.
A GT Player Express guide document is also included on the JamLab CD. For more detailed information on GT Player Express, please read this
document.
Control Panel
In Mac OS X, go to your System Preferences and double-click on the JamLab icon.

In Windows XP, go to your Control Panels and double-click on the JamLab icon.
This will bring up the JamLab Control Panel.
The Input Gain tab allows you to boost the input signal from your guitar to the computer. If you’re using a guitar with single coil pickups, you’ll
want this setting to be close to 10. If you’re using a guitar with humbucking pickups or active pickups, you’ll want this setting to be closer to 0.
Setting the level all the way to 0 will mute the guitar input.

The Output Levels tab allows you to control the overall output level of the JamLab. If you’re hooking the JamLab up to headphones or powered
speakers WITHOUT a volume knob, you’ll want this setting to be closer to 0. Start low, and then turn up the output volume until you find the right
level for your headphones or speakers. The Link button allows you to control the output level of the left and right signals at the same time. If you
click on the Link button, the check mark will go away and you can control the left and right volume separately. Clicking on the Link button again
will re-link the left and right volume faders. Clicking the Mute button basically turns the output of the JamLab off.
The Performance tab allows you to set the bit-depth of JamLab. The default setting is 24-bit, however 16-bit is available should you need to use
JamLab with an application that does not support 24-bit operation.

The About tab contains useful information about your JamLab. Should you ever need to call M-Audio tech support for help with your JamLab,
the information on this screen will be asked for. This tab also has a “Check for driver updates” link. If your computer is connected to the Internet,
clicking this link will search the M-Audio website for an updated JamLab driver.
Playing with the effects
Launch the GT Player Express application.
First, click on the Options key (4) located on the right side of the effect rack. A drop-down list will appear. Click on Preferences.

Click on the Audio tab and adjust the settings so that they match the screen shots below for Mac OS X or Windows XP. Then click Close on the
Mac or OK on Windows.

Click the Power button (1) on the effect rack and the button will light up. Use the Dial (2) to select the preset Rock Solo and click on the Load button
(3). You can now play your guitar and hear the effects. The effects pedals used to create that preset will appear on the screen. Use your mouse
to adjust the pedal parameter values. Use the Output knob (5) to adjust the volume.
If your input level is too low, go back to the JamLab Control Panel and turn up the Input fader there. Do NOT turn up the input level on the GT Player
Express rack effect. Keep using your Dial (2) and Load button (3) to try out different presets.
Using the Track Player
The Track Player allows you to load in files to play along with. On Mac OS X, you can load .MP3, .WAV, .AIFF, AAC and MP4 files. On Windows XP
you are limited to .WAV files.
Your JamLab CD includes 165MB of M-Audio’s ProSessions drum loops in .wav format so that they can be used on Mac OS X and Windows XP.
These files are recordings of real drummers playing small parts of songs that you can chain together to make your own songs.

In Windows XP, the Track Player comes loaded with a playlist made of M-Audio ProSessions .WAV files as an example.
Click on the Power button (1) and press the Play button (4). The files will play and you can jam along. If your guitar sound is overpowering your
drum playback volume, turn up the Output (5) on the Track Player.
M-Audio ProSessions loops are provided in song parts: Intro, Verse, Chorus, Bridge, Ending, etc. The GT Player Express Track Player has a repeat
function that allows for seamless loop-to-loop playback. The Track Player also has two repeat modes: Play One or Play All. Play One allows you
to load one drum loop and have it repeat over and over. Play All allows you to load a playlist of loops, which allows you to put your loops in order
like a song. The Track Player will play all of the loops in the order that they are listed, and then repeat the playlist from the beginning when the
last loop is played.
To use the ProSessions drum loops, you must first copy the .WAV folder from the JamLab CD to your computer’s desktop. Then, launch GT Player
Express. Be sure to click on the power button for both the GT Player and the Track Player.

Now click on the Playlist button, which will bring up the Playlist Editor window. Click on the Add button.
Locate the .WAV folder on your desktop. Now click on the “Slam It Drum Loops 68” folder and click “Open.”
