Disk Operations - Yamaha Portatone PSR-640 Owner's Manual

Disk Operations

Built into the PSR-740/640 is a disk drive. Simply insert a floppy disk, and you've got access to a wide
variety of convenient functions, such as recording and playback of User songs (page 92), as well as saving
and loading of User styles (page 110), User pads (page 106), and Registration Memory data (page 62).
You can save any number of User styles/pads and registration data to floppy disks, create your own song
libraries, or find many other ways to make playing and using the PSR-740/640 more efficient.
The PSR-740/640 is capable of playing back songs contained on the included
sample disk, as well as commercially available song data in the following formats,
indicated by the corresponding logos (page 9):
You can play back song files collected on these disks using the
voices defined in the GM standard.
You can play back songs using the XG format, an extension of the
GM standard that allows for much higher sound quality.
You can play back song files collected on these disks using the
voices defined in Yamaha's DOC format.
The PSR-740/640 is compatible with style data contained on the included sample
disk, as well as commercially available disk styles in the following format,
indicated by the corresponding logo (page 9):
You can load and play with the style files collected on these disks.
You can record your own performances to User songs and play them back (page
92).
The PSR-740/640 features special User style, User pad and Registration
Memory functions. The data recorded with these functions can also be saved to
disk individually or in any combination. Likewise, data (files) saved to disks can
be loaded individually or in any combination to the PSR-740/640.

• Refer to page 9 for more
details on the logos.
• It may not be possible to
record the full 60 files to a
disk, depending on the
length of the recorded files.
• The maximum number of
files may vary according to
the type and volume of the
saved files (page 69).
• When saving data, use a
floppy disk formatted on the
PSR-740/640.
• The three letters following
the file name (after the
period) are referred to as a
file "extension." The
extension indicates the type
of file.
• Since the user songs are
directly recorded to the disk
as you play during recording
and read from the disk
during playback, the Save/
Load functions are not
available. The Copy and
Delete File operations
related to the user songs can
be executed.
