should not be Playing, Recording or Overdubbing when you
remove the card. If you do remove the card during Recording
or Overdubbing, you could damage the card’s file system
where the 45000 does not properly read or write to the card.
If this occurs, connect the 45000 to a Windows PC with a USB
cable and run the Scandisk utility on the card. If the card still
does not work re-format the card for FAT32, unfortunately you
will lose all loops that are on the card.
USB Port
The 45000 is fitted with a USB Port allowing you to move your
files to and from your computer using a standard USB cable.
The USB Port is located on the right side of the 45000, next to
the SD card slot.
When you connect your 45000 to a computer, through the
USB connector, it will display the SD card inside the 45000 as
a “Removable Disk.” You may then copy files to and from the
SD card. The 45000 is automatically recognized by PCs run-
ning Windows XP or later or Macs running OS X.
The 45000 records all audio files as wave files (.wav), which
can then be read by most if not all modern computers. Any
audio program that accepts wave files as a viable format
can play or edit the 45000 audio files. Every PC and Mac can
play wave files. The biggest plus is the ability to insert your
45000 files into your favorite software application; a sound
designer’s dream!
45000’s SD Card File System
Using a PC or Mac, you can import audio files made else-
where into the 45000 or backup and restore loops to the SD
card inside the 45000. When you look inside the SD card’s
file system, each loop will have its own folder labeled from
LOOP00 to LOOP99. Only the loop numbers that have been
recorded will have a folder. For example, if you have never
recorded onto Loop 20, there will be no folder called LOOP20.
Double-click one of the loop folders and you will see there
are 6 files inside the folder. The names for the 6 files are the
same in each loop folder: TEMPO.TXT, TRACK1.WAV, TRACK2.
WAV, TRACK3.WAV, TRACK4.WAV, TRACKM.WAV.
Backing Up Files
The best way to back up any given loop would be to copy
the loop’s entire folder to a preferred directory on your com-
puter’s hard drive. You may want to change the name of the
Loop folder once on your hard drive to easily determine the
contents of the folder.
When backing up it is important to save all 6 files in the loop
folder including the five audio files and the TEMPO.TXT file.
The 45000 will only play a loop if all audio files are present
and may not play as intended if TEMPO.TXT is not present.
Restoring Files
To restore a loop, locate the loop folder on your hard drive.
Copy the entire Loop folder into the 45000’s SD card root
directory. If necessary, rename the folder to LOOPxx, where
xx is an available loop number between 00 and 99. You do
not need to restore to the same loop number the loop was
originally recorded with.
When restoring files to the SD Card, it is important to include
all five audio files and the TEMPO.TXT file. The 45000 will
only play a loop if all audio files are present and may not play
as intended if TEMPO.TXT is not present.
Importing Audio Files
The 45000 is capable of Playing and Overdubbing audio files
that are made elsewhere then imported onto the SD card
using a computer and USB. There are some important specifi-
cations that need to be followed in order for the audio import
to work correctly:
• The audio files must be in the .wav format.
• The .wav files must have 16-bit resolution and a sample
rate of 44.1 kHz.
• You must have all four mono track files present as well as
the stereo mix file and TEMPO.TXT.
• It is recommended that all five audio tracks be at the same
length, though if they are not, the .wav file of shortest
length will set the loop length for all of the tracks. For exam-
ple if you are importing five .wav files of varying length and
TRACK2.WAV is the shortest at 5 seconds. When you play
the loop on the 45000, it will cycle all tracks at 5 seconds,
the longer tracks will essentially be truncated to their first
5 seconds.
• The TEMPO.TXT file should be copied from an established
loop. In the second line, where it says TEMPO = xxx.xxxxx
bpm, insert the BPM that you created the loops at. When the
45000’s TEMPO slider is set to that tempo, the TEMPO LED
will light up and the loops will play back at normal speed.
The field that is labeled TEMPO POT should be left blank.
• You can copy the imported files to either a Loop folder
already on the SD card, though in this case you will be eras-
ing whatever is in there at the moment, or you can create a
new Loop folder giving it any number between 00 and 99.
Changing Loop Number Using Just
the 45000 Main Unit
The 45000’s SD card can hold up to 100 loops at a time. The
easiest way to change loops is by using the optional 45000
Foot Controller. The 45000 Foot Controller displays the cur-
rent loop number or the loop you are changing to. If you have
the correct type of MIDI controller, we would also recommend
using MIDI to change loop numbers. If neither is possible, or
you’re in a pinch, you can also change loop numbers on the
45000 main unit without anything else connected to it. Here’s
how to change loop numbers:
1. Make sure the 45000 is powered up and idle. It should not
be recording, playing or overdubbing a loop.
2. Press and hold the STEREO MODE button. After approxi-
mately 2 seconds you should see all 4 track LEDs light up
solid. Keep holding down the STEREO MODE button.
3. While you continue to hold down the STEREO MODE but-
ton, use the OCTAVE and REVERSE buttons to change the
loop number. OCTAVE increments the loop number by 1.
REVERSE decrements the loop number by 1.
4. Release the STEREO MODE button when you have selected
the loop number you want to work with.
5. Unfortunately there is no way to know what loop number
you are starting with or which loop you have selected. The
factory default is LOOP00. You can check to see if the loop
is empty by pressing PLAY. If the 45000 remains idle, then
you have selected an empty loop number. If the 45000
begins playing back then there is a loop already stored in
memory at the location. Of course you could overwrite this
loop if you like by going through the New Loop procedure.
