File Area - Yamaha CP4 Stage Reference Manual

File Area

In the File area, you can save Performances created using your stage piano on a USB flash-
memory device, and read data from this type of device. To return to the Performance screen from
the File area, press the [EXIT] button.
File-related terms
A number of terms will be used in the following descriptions of File area functions and operations.
Please take a moment to familiarize yourself with their meanings in order that these functions and
operations can be more easily understood.
File
The term "file" is used to define a collection of data stored on a memory medium. Data saved to a
USB flash-memory device by your stage piano or a computer takes the form of files, and this format
is also used when reading data back from a USB flash-memory device. A file is identified by a file
name and an extension, as described below.
File name
On the CP4 STAGE and CP40 STAGE, files can be assigned a name containing up to eight
alphanumeric characters and symbols. These names are used to tell files apart, and for this reason,
no two files within a specific directory can share the same file name. Computers are capable of
handling very long file names that can even include non-English characters, but on your
CP4 STAGE or CP40 STAGE, non-English characters will be replaced with symbols and long names
will be truncated to six or seven characters.
Extension
The three letters following the period at the end of a file name — such as ".mid" and ".wav" — are
referred to as a file extension. The type of data contained within a file is identified by its extension,
and it is not possible to specify or change an extension using the CP4 STAGE or CP40 STAGE.
File size
The amount of memory needed to store a file is indicated by the file size. These sizes as well as the
capacities of memory devices are presented in standard computer format using B (bytes), KB (kilo
bytes), MB (mega bytes), and GB (giga bytes). (1 KB is equivalent to 1,024 bytes; 1 MB is
equivalent to 1,024 KB; and 1 GB is equivalent to 1,024 MB.)
Directory
A hierarchical system of directories is used on USB flash-memory devices in order to group files
together according to type or application. In this regard, directories are equivalent to the folders
used on a computer. As with files, you can assign names to individual directories, but directories do
not have extensions.
Root directory
The directory initially displayed when you open a USB flash-memory device on a computer or the
like is referred to as the root directory.
Mounted
A USB flash-memory device is said to be mounted when it has been connected to the instrument,
the instrument has identified it, and it is ready for use. Your CP4 STAGE or CP40 STAGE will
automatically mount a USB flash-memory device whenever plugged into the [TO DEVICE] USB
terminal. Incidentally, a device that is no longer mounted is said to be unmounted.
Formatting
The operation of initializing a USB flash-memory device is referred to as formatting. Whenever you
format such a device, all of its files and directories (or folders) will be erased.
Save and load
The term "save" refers to the writing of data to a USB flash-memory device for storage, while "load"
refers to the reading of files from this type of device into the instrument's internal memory. In
contrast, the term "store" is used to refer to writing of data to the internal memory.
