Songs 7•1
WHAT IS A SONG
A Song is a multitrack recording of several in-
strumental parts, each corresponding to a track.
WK4 can load Songs from disk in its own format
(Song), in previous compatible formats (WX, SX),
in standard MIDI file format 0 or 1 and in
Tune1000
™
format.
WK4 Songs are ‘free’, that is, tracks can be re-
corded starting from any point, without start or
end segment limitations, which characterize most
sequencers.
The “Edit Song” functions allow you to modify the
recorded song, by copying or moving entire parts
of a song, by correcting timing errors, by insert-
ing events in ‘event edit’ environments (Micro-
scope and Master Track).
Tracks contain MIDI events, that is, notes and
control data. Control data can include PitchBend
and Aftertouch messages, ProgramChange and
BankSelect messages for sound changes,
ControlChange messages to control the effects
sends, Sustain pedal and other control param-
eters.
MIDI events recorded on tracks are not the inter-
nal Wave sounds, but messages which activate
the WK4 internal sound generator or an expander
controlled by WK4. A Song is a MIDI event list –
a list for each track.
General control messages are recorded in the
Master Track. These messages relate to the in-
strument in general, such as effects change or
Performance selections.

WHAT IS A STANDARD MIDI FILE
A Standard MIDI File is a storage format created
to maintain data compatibility among different
devices complying with the Standard MIDI File
format. This format allows Songs to be ex-
changed between different instruments and com-
puters. If a Song is saved as a MIDI file on an
MS-DOS disk, you can be certain that all the most
recent generation of instruments and sequencers/
computers will be able to load and read that Song.
General MIDI
To facilitate compatibility between different makes
of instruments, MIDI files should be in General
MIDI standard, a common platform for sounds
and the way they are selected.
General MIDI stipulates common standards re-
garding the listing of sounds, Program Change
numbers for sound selection, the percussive
sound configuration in the Drumkits, the assign-
ment of MIDI channel 10 to the Drumkits, a mini-
mum polyphony (24) and a maximum number of
tracks (16).
In WK4, Sound Bank 1 and Drumkit Bank 2 are
fully GM compatible. WK4 recognizes GM com-
patible MIDI Files, thanks to a messages contained
in the MIDI File (General MIDI ON flag). If this
message is not detected, sounds that differ to a
Drumkit may be assigned to MIDI channel 10.
To ensure correct loading of GM compatible MIDI
files that do not contain the General MIDI ON flag,
set the General MIDI parameter to ON in the
“General Set” parameter of «Edit MIDI» before
loading.
WK4 can save GM compatible MIDI Files when
the General MIDI parameter is set to ON. MIDI
