Each instrument equipped with a disk drive uses its own format for the disks and Songs.
This format is not directly legible by other musical instruments. For example, an S Series
instrument is not able to read a Song created and memorised to a disk by a WX Series
instrument.
The S Series and many of the more recent instruments and sequencers can save Songs in a
format called “Standard M
IDI
-file”* on M

or Atari format disks.
Compatibility of the sounds (M
IDI
-files in General Midi/GS standard)
When a musical instrument reads a M
IDI
-file created by a different musical instrument, it
is highly probable that the song selects incorrect sounds. Most instrument, in fact, organ-
ise their sound maps in a non-standard manner.
General Midi (GM) and GS are standards adopted by most manufacturers, conceived to
standardise the organisation of the sound maps in different musical instruments. For
example, the S Series — which is compatible with General Midi and with GS — has a
Sound Library organised in a manner similar to the sound maps of other General Midi/GS
compatible instruments.
As well as the sound mappings, General Midi/GS also renders drumkits compatible. In
General Midi/GS
STANDARD
M
IDI
-files, the drumkit is assigned to M
IDI
channel 10. (By
default, in the Performances of the S Series, M
IDI
channel 10 is assigned to track 10).
General Midi Standardising regulations for sound maps to apply to different musical instruments.
GS An extension of the General Midi standard. Standardises the Program Change numbers of
drumkits.
Midi channel 10 Reserved for the drumkits. In the S Series, Midi channel 10 is assigned to Track
10 of all the Performances by default.
Activation of the General Midi/GS compatibility
The default status of the S Series does not fully comply to General Midi: the program
change numbers that recall the drumkits on M
IDI
channel 10 differ to those specified by
the standard.
To render the S Series fully General Midi/GS compatible, it is necessary to activate the
“General Midi” parameter (in
EDIT GENERAL
).
When the General Midi/GS compatibility is active (on), the exchange of M
IDI
-files (and
M
IDI
communications) between the Music Processor and a General Midi/GS instrument is
instant and does not require further adjustments. The correct drumkits will be recalled on
Midi channel 10.
