When you connect external MIDI devices, the
corresponding tracks must be tuned to the same
MIDI channels as the WK4 tracks. Some exam-
ples follow, with WK4 programmed as shown in
the previous table:
• If a single WK4 track (Upper 1 - track 8) con-
trols an expander, the expander must be pro-
grammed to receive on MIDI channel 8.
• If WK4 controls a multi-timbral expander, the
instrumental parts of the expander must be
tuned to the same MIDI channels as the WK4.
Assign MIDI channel 10 to the drum track,
channel 9 to the Bass, etc...
• If WK4 is controlled by an external control-
ling device, you must program the parts
(tracks) of the controlling device to the same
channels as the WK4. Alternatively, program
the WK4 accordingly to react with the mas-
ter.
THE COMMON CHANNEL
The Common Channel is used to:
• simulate the WK4 keyboard with a master
keyboard. The master keyboard must trans-
mit on the same channel as the WK4 Com-
mon Channel.
• dedicate a special track in a sequencer or
other instrument for the selection and con-
trol of Styles, Performance, Songs and Ef-
fects. In the external sequencer, a track is
reserved for the transmission of control data
which travels on the same MIDI channel as
the WK4 Common Channel.
The track assigned to the Common Channel can-
not be used for the normal tracks.
NUMERATION
The numeration of MIDI data usually adopts the
system 0-127. Some instruments adopt the sys-
tem 1-128. When devices are used that adopt a
different numeric system, it is necessary to apply
the conversion between one system and the
other.
In WK4 the Control Changes and relative values
follow the system 0-127. For example, the Bank
Select values range from 0 to 127.
The Program Change values, instead, follow the
numeration 1-128.
