Velocity
originally
expressed
the
speed
at
of
a
key
press,
but
now
stands
for
the
amount
of
pressure
applied
to
a
key.
It
can
be
any
one
of
the
127
values
in
the
range
from
1
to
127,

* Each of the preset tones has a specific range in which it can sound (see “Note Table” on pages
A-3 and A-4). If a note number received exceeds its upper or lower range, the same note in the
nearest upper or lower octave is used instead.
PROGRAM CHANGE
This message indicates tone selection as a value in the range of 0 to 127. Whenever you select a
tone on the WK-1500, the corresponding data is sent out as a PROGRAM CHANGE message
through the MIDI OUT terminal. PROGRAM CHANGE data can also be used to change the
WK-1500's tone setting from an external device.
PITCH BEND
This message controls upward and downward bending of the pitch of a note. Rotating the WK-1500’s
pitch bend wheel causes corresponding data to be sent out as a PITCH BEND message through the
MIDI OUT terminal.
CONTROL CHANGE
This message is used to add vibrato or to change the volume of a tone. The CONTROL CHANGE
message includes the following information.
¢ CONTROL NUMBER: effect identifier
* CONTROL VALUE: effect depth, on/off setting
The WK-1500 can send and receive the following CONTROL CHANGE data.

“RPN”
stands
for
“registered

which
is
a
combination
of
multiple

The WK-1500 uses RPN to control PITCH BEND SENSE, TRANSPOSE, and TUNE.
Note
«
Use
of
an
optionally
available
pedal
makes
it
possible
to
send
and
receive
SUSTAIN,
SOSTENUTO,
and SOFT effects (CONTROL NUMBERS 64, 66, 67).

RESET ALL CONTROLLERS
This message initializes the settings of pitch bend and all controflers.
SYSTEM EXCLUSIVE(*) ; ; ;
This message provides a means to made detailed tone settings and control functions that are
specific to a particular device. ;
The WK-1500 supports the following SYSTEM EXCLUSIVE settings.
« GM SYSTEM ON ([FOJ[7E}[7F][09][01][F7]) ; ; :
This SYSTEM EXCLUSIVE returns the WK-1500 to its General MIDI basic settings.
GM SYSTEM ON takes more time to process than other messages. Whenever you record a
GM SYSTEM ON message in sequencer data, always provide an interval of at least 5|0msec
(50/1000 second) before the next message.
* GENERAL MIDI SYSTEM OFF ([FO][7E][{7F][09][02][F7])
Receipt of any of the above messages disables the WK-1500's General MID] System.
EFFECT CHANGE ([FO][44][OB)[09][XX][F7])
This SYSTEM EXCLUSIVE switches the built-in digital effect type. A hexadecimal effect
number that identifies the digital effect being changed to is input in piace of the “xx” in the
above SYSTEM EXCLUSIVE message, and then the message is sent from the sequencer
(computer) to the WK-1500. The table below shows the hexadecimal numbers that identify
each of the digital effects.

Receive Only MIDI Messages
The following MIDI messages only can be received by the WK-1500. Note that messages in this
section marked with an asterisk affect overall WK-1500 operation. Messages without asterisks affect
particular MIDI channels.
CHANNEL PRESSURE
This message is output when additional pressure is applied to keyboard keys after they are already
depressed. With the WK-1500, CHANNEL PRESSURE and MODULATION are the same, and
receipt of either messages causes vibrato to be applied. Vibrato is turned off when either CHANNEL
PRESSURE or MODULATION is turned off.
RPN NULL
This message initializes any parameter being controlled by RPN.
