• 5 Disk (PK7 only)
Note: WK4 Songs disks
saved as MIDI Files are rec-
ognized only if WK4 data
conforms to the GMX for-
mat, a General MIDI exten-
sion exclusive to General-
music which renders the first
three banks of all PK, WK
Series units fully compatible
(except PK5 which has only
2 Sound banks and no disk
drive).
Working with disks provides you with a means of building a library of Sounds, Samples, Performances, Styles,
Songs and Song Style that can be loaded into the PK7 RAM at any time.
As you become more familiar with your PK7, you’ll discover the practical uses of working with disks, because
of the flexibility and power that they offer.
This chapter introduces you to the concepts of Files, Disks and RAM Memory, explains the principal Disk
functions by showing you how load and save Songs, Styles, Performances, Samples and MIDI Files and other
files compatible files.
If this is the first time you are using floppy disks, you are recommended to refer to the pages at the end of this
chapter which discusses disk handling precautions, how to insert and extract disks and other general informa-
tion.
Floppy Disk formats
PK7 handles 3.5" HD and 3.5" DD disks. These are of the most commonly used type, available in office
stationer’s, supermarkets and computer outlets.
PK7 is able to read data stored on disks in one of the following formats: PK, WK; MS-DOS, Atari ST/Falcon,
and Generalmusic CD Series disks.
PK7 is not able read Song, Style and Sound data in non-Generalmusic instrument formats. The exclu-
sive format of musical instruments adopted by one manufacturer is incompatible with instruments of other
manufacturers. To exchange Songs with instruments of other manufacturers, the Song must be saved as MIDI
file format data to an MS-DOS formatted disk.
FILES
Data is stored on disks in the form of files. Files identify Songs, Song Styles, Performances, Styles and
Samples.
The contents of a PK7 format disk comprises a set of files which reflects the structure of the instrument’s
internal memory (RAM).
File Types and extensions
The types of File encountered when working in the PK7 Disk environment are identified by a name (which
appears in the 8 digit display area) and an extension (shown in the 3 digit display area) which identifies the type
of file.
In file types that include SONGS in the PK and WK format, STYLES and ALL, the extension is not displayed.
The extensions of all other recognized file types are listed in the paragraph explaining the LOAD function
afterwards.
