MIDI CONNECTION RULES

• An instrument which pilots another instrument is called the master, while an instrument
that is piloted by a controlling device is called the slave.
• The MIDI OUT of the master instrument is connected to the MIDI IN of the slave instru-
ment.
• To programme Songs on an external sequencer, the MIDI OUT of WK2 is connected to
the MIDI IN of the sequencer; the MIDI OUT of the sequencer is connected to the MIDI
IN of WK2.
• Do not connect the same MIDI port between two instruments.
When you connect external MIDI devices, the tracks of the external devices and those
of the WK2 must be tuned to the same MIDI channels.

ASSIGNING MIDI CHANNELS

The MIDI channel configurations of each Performance are freely programmable and can be
memorised with the STORE PERFORMANCE function.
The procedure for channel assignments is explained in the MIDI/GENERAL chapter.
The MIDI channels are independently programmable for each track.

MIDI LOCK

If you enable MIDI LOCK (set to ON in MIDI/GENERAL) before programming the MIDI
channel configuration of a Performance, the current configuration will remain fixed for all
other Performances. All the other configurations associated to other Performances will be
overridden.
The last programmed configuration will remain memorised after power down, provided that
the Store Performance operation is carried out using the first Performance as the destina-
tion (the first Performance corresponds to the power-up Performance).

THE COMMON CHANNEL

The Common Channel is primarily used for the sending and receiving Performance mes-
sages. A Program Change message received on this channel will not change one of the
individual sounds on the keyboard, it will be interpreted as a Performance Change mes-
sage.
The two main uses of the Common channel are:
• to simulate the entire WK2 keyboard with a master keyboard. The master keyboard
must transmit on the same channel as the WK2 Common Channel.
• to dedicate a special track in a sequencer or other instrument for the selection and
control of WK2 Styles, Performances, Songs and Effects. In the external sequencer, a
track is reserved for the control data which is transmitted on the same MIDI channel
assigned to the WK2 Common Channel.
The track assigned to the Common Channel cannot be used to transmit note data as occurs
for the "normal" tracks.

CHORD CHANNEL

The Chord Channel is reserved for the connection of a MIDI accordion. The Chord channel
is used to receive chord information from the MIDI accordion and to control the automatic
accompaniments of the WK2.
Use the standard MIDI channel assignment procedure to assign the Chord channel. Press
ESCAPE to return to the main menu. Hold down STORE PERFORMANCE the press
ENTER to memorise the MIDI configuration to the current Performance.
