Examining a PC File Directory from a PSR Screen
From Floppy to PSR
To help you understand the PSR file system,
let's perform a bit of a laboratory experiment. We are going
to move some files to a floppy and then see what happens when that
floppy is taken to your keyboard. Of course, you don't have
to do this; you could just follow along with the text, but trying
things out for yourself is always much more informative. I
have created an example
floppy disk to use. You will need
to download the ZIP file, unzip the contents, and put them on a
floppy disk. Double-click on the "example floppy disk" in
the previous sentence to download the files. If you need help
downloading, review our Downloading
section.
I have put a couple of examples of many different
file types on this disk. If you examine the disk directory
in your PC -- using the Details option -- you will see 11 files
as shown in the figure below. You don't have to put the zip
file on the floppy disk, but it won't hurt anything to be there.
The disk has two MIDI Sequence files, which will be recognized as
"SONGS" when you put the disk in the PSR. That is, if from
the MAIN screen, you press [A] to bring up the SONG display menu
and press [NEXT] a couple of times to examine the FLOPPY DISK, you
will see only two entries: AG-InTheMood and RP-Georgia.
You will not see the size of the file or the type of the file, in
this case MIDI sequences. You will also NOT SEE any other
files from the SONG menu. The only thing the SONG menu shows
is SONG files (i.e.".mid" files) that are on that floppy disk.
By the way, the songs are prefixed with the performer's initials:
AG -- Alex Green, and RP - Richard Peck.
 The
figure shown here illustrates how the files on the floppy are interpreted
by the PSR-2000. The two multipad files (extension of ".pad"
) show up when you press [I] from the MAIN screen to bring up the
multipad screen.
The two registration files show up on the
REGISTRATION BANK screen. The two style files show up on the
STYLE screen. Finally, the two voice files are displayed on the
VOICE screen.
The disk will also contain a Music Finder
file (extension ".mfd" ) which we won't discuss in this lesson,
but which will come in handy later when explaining the Music Finder
Database.
Common File System
Notice that from the MAIN screen you can
directly access five different kinds of files: song files, style
files, voice files, mutli pad files and registration files.
In every case, the file access screen is essentially the same.
There is a new screen title, of course, and the Registration Bank
screen only has two tabs instead of three (there are no PRESET registration
files.) Another difference in the REGISTRATION BANK screen
is the EDIT button in the bottom right-hand corner. Since
a registration bank file actually contains 8 individual registrations,
you can edit the file and provide a name for each of those eight
registration buttons if you like. You can also delete individual
registration button contents via this edit screen.
The MAIN screen is not the only place where
you will encounter this file system interface. Press the DEMO
button and you get exactly the same system from which you select
the demo files you want. In discussing the Demos
in the PSR-2100 we explained how to navigate this file
system. In that lesson we discussed
- How to move between the different storage
areas (PRESET, USER, and FLOPPY DISK) by using the [BACK] and
[NEXT] buttons.
- How to select different pages ([P1] ...
[P10]), which are needed when more than 10 files exist for a particular
kind of file, by using the numbered buttons ([1] ... [8]), and
- How to select a file or folder by using
one of the 10 lettered buttons ([A] - [J]).
If you need help navigating through this
file system, do review the demo lesson. Because, as the figure
above clearly shows, once you have mastered navigating the file
system for one type of file, you have mastered it for all types
of files since they all employ the very same user interface.
In the next lesson, we will discuss how you manipulate these files
(copy, paste, etc.).
Try the Files Out
By the way, the files provided for this demonstration
are real files you can use in your PSR-2000. We've already
discussed the two songs, both of which are available from our PSR-2000
Performer's page (or will be as soon as we get that section completed!).
The multipad files are from a collection provided by Michael Bedesem.
The registration files are discussed in our registration
lesson. The two style files are by Simon Williams and are
from the collection available on our download
page where each style has been tuned to the PSR-2000 and has has
OTS added. The two voice files were provided via messages
in the yahoo-psr-styles
forum . Finally, if
you still have your original Music Finder Database file, you are
undoubtedly aware that the song titles in that database are modified
so that they DO NOT match the exact title. This file has the
correct titles.
