Welcome to BackTrack

BackTrack makes it easy for you to capture and replay any moment of musical inspiration, without preparing to record it in advance.

BackTrack can constantly capture everything you play to its internal Flash memory. It notices when you start and stop playing, and automatically splits out individual audio events for each of these musical moments.

This makes it easy to mark individual events as ones that you want to save and return to. After one of these happens, press the MARK button, and BackTrack will mark this as something important that it will keep. Press the play button, and you can hear that event played back again, giving you instant replay for inspiration.

It’s also easy to select any other marked event to play back. Playback can be looped, so you hear one particular event over and over again, while you jam on other ideas to go with it. You can also choose to revew all the audio in BackTrack’s memory, just in case there was some other recent moment that you didn’t mark, but want to return to.

Connect BackTrack to your computer, and you’ve got access to all these audio events as individual .WAV files. There’s one folder for the MARKED events, and another folder for the UNMARKED ones. The MARKED files will never be erased by BackTrack, unless you remove them yourself while connected to the computer. The UNMARKED files may be deleted by BackTrack when it needs to make room to capture newer audio events.

Make copies of the files on your computer to build up a library of inspiration, burn them to CD, or convert them to MP3 to share them with your fans or collaborators. You can play them in your favorite audio software, and even load them into your recording software as a foundation for a fuller recording of your ideas.

You can also put other .WAV files in the USER folder on BackTrack to have them available for playback away from your computer.

The included software lets you choose the quality settings that will be used for audio capture. BackTrack supports CD-standard 44.1 kHz, 16 bit quality, as well as settings up to 48 kHz, 24 bit. Chose lower settings to increase recording capacity, or higher settings for pristine audio quality. (See pages 9 thru 12 for details.)

For added versatility, BackTrack also includes these features:

• Flip the switch to PLAY ONLY for those times when you don’t want auto capture

• Forced Capture lets you use BackTrack as a regular recording device, for planned recordings (see page 4)

Audio Playback

Prepare to hear playback

• For audio captured direct from a guitar’s output, connect OUT jack to your amp, POD etc. like a stomp box, before any other stompboxes, so it feeds signal to your setup just like your guitar does

• Or connect hear playback. This is the preferred set up, for instance, if you’ve recorded from the mic.

Choose to play back only marked events, or all audio

• Set PLAY MARKED/ALL to PLAY MARKED to hear only marked events when playing back

• Set PLAY MARKED/ALL to ALL to hear all audio, including marked and unmarked, when playing back

Select audio events for playback

• Press

Loop playback

• The BackTrack Setup Utility software lets you enable or disable looped playback

Computer

Connected to computer

• BackTrack will automatically charge its battery and mount as a mass storage device (appears on your computer like a CD-Rom, Flash Drive, etc.) when its USB jack is connected to a computer

• While mounted, normal BackTrack operation is defeated: audio capture and playback are disabled

• To unmount from Windows®, click “safely remove hardware” icon in your onscreen System Tray, and remove BackTrack. If unsuccessful, quit Backup Setup Utility, close all files, and disconnect USB cable to unmount.

• To unmount from Mac®, drag BackTrack icon to trash (eject icon replaces trash icon as you are dragging)

BackTrack Setup Utility

• For Windows, install BackTrack Setup Utility by launching installer available from BackTrack when mounted on computer

• For Mac, a disk image (a .dmg file) is provided: double-click it to mount a disc image that contains the

BackTrack Setup Utility, which you can then drag to your computer to install

• Set date and time from utility software so files created by BackTrack will have accurate date/time information

Windows Requires .NET Framework 2.0 or Higher

The Windows version of the BackTrack Setup Utility requires the Microsoft .NET Framework version 2.0 or higher. This is included in the BackTrack Setup Utility Installer, available for download from www.line6.com/software, and on BackTrack, accessible from computer when mounted via USB. Microsoft .NET Framework version

2.0 can also be installed using Windows Update or by installing the "Windows Installer Redistributable"

version 3.1 or higher and the “.NET Framework Version 2.0 Redistributable Package” which are available for download from Microsoft’s web site.

Files

• BackTrack stores audio as .WAV files

• The BackTrack MARKED folder/directory holds all marked audio

• The BackTrack UNMARKED folder/directory holds the other captured audio that was not marked

• Drag any of these audio files from MARKED or UNMARKED to your computer to copy/backup

• Double-click any of these audio files to play in your default audio player software

• To have additional .WAV’s available for playback from BackTrack, put them only in the USER folder/directory

• Files stored in the UNMARKED folder/directory may be deleted by BackTrack during normal operation

• Files stored in the MARKED folder/directory are never deleted by BackTrack during normal operation

• BackTrack can play properly formatted mono or stereo .WAV files that are:

• 16 or 24 bit word length

• 11, 22, 32, 44.1 or 48 kHz sample rate

Page 10

Files (continued)

• BackTrack can not play files such as .mp3, .m4p, .AIFF, compressed or .WAVs that don’t match the file options

listed on the previous page

Sample Rates Over 48kHz

• Attempting to play a .WAV file created at a sample rate higher than 48kHz may cause that file to play at odd

speeds, etc.

Audio Files Created By BackTrack

• Files created by BackTrack will be named beginning with “BT”, followed by a 5 digit number, then “G” (if the

audio was recorded from 1/4-inch guitar input) or “M” (if the audio was recorded from mic), then “.WAV”.

Erasing Files

• You can erase files while BackTrack is mounted on a computer to free up space for additional audio capture

• Copy these files to your computer first if you do not want to lose them permanently

• After installing the utility software, you can delete those files from BackTrack to maximize audio capacity

Storing Other Files On BackTrack

• You can store other files on BackTrack, to transport them between computers. If you want to do this, we recommend that you create a “MY FILES” folder at the top level “root directory” of BackTrack (the same location that holds the MARKED and UNMARKED folders). Place your other files in that folder. This will help ensure that you don’t get these files confused with the files that BackTrack creates. No matter where you put files, they should be ignored by BackTrack, and not deleted, etc. even if they are in the UNMARKED folder.

Firmware Updates

• The latest firmware for your BackTrack is available for download from www.line6.com/software. To update your

BackTrack’s firmware:

1. Download the firmware file to your computer

2. Click the Update Firmware button on the BackTrack Setup Utility (as illustrated on page 13)

3. Locate the firmware file you just downloaded using the Open File window that is provided

Capacity

• The BackTrack Setup Utility software lets you select sample rate, bit depth and other audio capture settings

BackTrack + Mic BackTrack Sample Rate Bit Depth Notes

24 hours 12 hours 11 kHz 16 bit * 12 hours 6 hours 22 kHz 16 bit *

8 hours 4 hours 32 kHz 16 bit 6 hours 3 hours 44.1 kHz 16 bit CD audio standard 5 hours 2.5 hours 48 kHz 16 bit 4 hours 2 hours 44.1 kHz 24 bit 4 hours 2 hours 48 kHz 24 bit

* These settings are not recommended for mic full range audio, but may be sufficient for direct guitar

Colored Lights

• If your unit fails to operate normally, it may show a series of colors to help in diagnosing the problem

High volume audio can cause constant recording while auto capturing

Auto capture relies on periods of low volume to detect when a musical event ends. If audio always continues at a high level, it may never detect the end of an event, and may continue recording continuously. You may be able to improve this situation by setting the Auto Capture value to Loud in the Backtrack Setup Utility.
