Using xD Cards
You can use xD cards for all your backup and storage requirements. xD cards are sold in a 
variety of sizes; the PC3 will work with any size, so long as it’s 32MB – 256MB, Type S or no type 
stated, and formatted as FAT16. 
The xD card slot is on the back panel of the PC3, but it is easily accessible from the front of the 
instrument – just run your hand along the back panel at the right end (as viewed from the front); 
the blue light of the card slot will reflect off your hand. The gold contacts on the card must be 
facing up when you insert it into the PC3. You can remove an xD card anytime the blue “Storage 
Active” LED on the front panel is unlit.
Caution: Do not remove an xD card while the blue LED is lit; this can cause data corruption.
Formatting an xD Card
xD cards come formatted and ready to use with the PC3. If you ever need to format a card, 
however, insert the xD card (with gold contacts up) into the PC3’s xD slot, or in the xD slot of 
any computer with xD formatting capability. Make sure the card does not have a write-
protection sticker attached.
Press the Storage button to enter Storage mode. Press the soft button labeled Format. The PC3 
will ask you if you want to format, and a pair of Yes/No soft buttons will appear. Press the Yes 
soft button when you are ready to begin.
The PC3 will remind you that formatting will erase the xD card, and will give you two more 
chances to cancel the formatting procedure—we want to make sure you don’t accidentally erase 
any cards. Press the Yes soft button to continue formatting. When formatting begins, the display 
will tell you that the card is being formatted. The blue xD LED will light.
Directories
A directory lets you group files together as you might separate documents using folders in a file 
cabinet. You can create directories on xD cards. You can even create subdirectories within 
directories. Directories appear in the normal file list with the indicator <dir> to the right of the 
directory name.
Directories are handy for organizing your song, and program files. The PC3 provides many 
operations for setting up and managing directories and the files within them.
Path
The Path field shows the current directory on the current device. This field is displayed upon 
returning to the Storage mode page after you have pressed one of the Storage mode soft buttons 
and viewed the file contents. It stays visible on the Storage mode page until you power down or 
do a soft reset.
The PC3 always starts at the root (top-level) directory when you power it up, or when you 
change the value of the CurrentDisk parameter. When you use the disk functions to view other 
directories, the Path field updates the current directory value to track your movements.
