22500’s SD Card File System – All loops that you record on the 22500 are
placed into the Bank folders. The Bank folders are numbered 00 through 99 and
they match the Bank number you see on the 22500’s display when you scroll
through the banks. The Bank folders are titled BANKxx on the SD Card, where xx
stands for a number between 00 and 99. Only the bank numbers in which you
have recorded audio will have folders. For example, if you have never recorded
into Bank 20, there will be no folder called BANK20. If you erase a bank, the
bank folder remains but no audio files will be present.
All of the Rhythm Loops are located in the folders called LOOPxx on the SD Card.
The xx stands for a number between 00 and 99. From the factory, the 22500
comes supplied with 16 loops.
Using a PC or Mac, you can import audio files made elsewhere onto the 22500 or
backup and restore loops to the SD card inside the 22500.
Backing Up Files – The best way to back up any given loop or loop bank would
be to copy the bank’s entire folder to a preferred directory on your computer’s
hard drive. You may want to change the name of the bank folder once on your
hard drive to easily determine the contents of the folder.
When backing up it is important to save all files in the bank folder including one
or both audio files and the USERBANK.SET file.
Restoring Files – To restore a loop, locate the bank folder on your hard drive.
Copy the entire bank folder into the 22500’s SD card root directory. If necessary,
rename the folder to BANKxx, where xx is an available loop number between 00
and 99. You do not need to restore to the same bank number in which the loops
were originally recorded.
When restoring files to the SD Card, it is recommended to restore both the audio
files and the USERBANK.SET file. The 22500 may not play as intended if
USERBANK.SET is not present.
