¢ You can also specify 0 through 12 by pressing the corresponding 10-key pad
button.
* Pressing the [+] and {—] buttons at the same time automatically sets the key of C
(0).
« Remember that you have five seconds after displaying the current setting to
transpose the keyboard. Otherwise, the message will disappear from the dis-
play, and you will have to press the TRANSPOSE/TUNE button again to get it
back.
Important
e The above operation also causes pad sounds to be transposed.
¢ Each of the preset tones has a specific range in which it can sound (see the Note Table on pages
A-3 and A-4). If a transpose operation causes a note to exceed its upper or lower range, the same
note in the nearest upper or lower octave is used instead.
* The transpose setting returns to C(0) after play of a demo tune is finished.
* You can transpose the keyboard during Song Memory (page E-55) recording and playback, but
the transpose settings are not stored in memory. If you want to play back from Song Memory at the
same transpose setting that you recorded with, you have to make the same transpose setting
before playing back.
* The transpose setting clears the Mixer and MIDI parameter coarse tune setting and changes it to
the value set by all channel transpose.

| Part 6 | Using MIDI
@ What is MIDI?
“MIDI" stands for Musical instrument Digital Interface, which is a worldwide standard for the ex-
change of digital signals produced by electronic musical instruments and devices. MIDI lets you
easily exchange data with other MIDI devices, regardiess of maker or model. MIDI data includes
information about whether a keyboard key is depressed or released, when a tone setting is changed,
etc. Data is exchanged using what is known as “messages.”
The WK-1500 can be used as a stand-alone keyboard without any knowledge of MIDI and how to
exchange MIDI data. The following information is presented for those who wish to connect the
WK-1500 to another keyboard, a computer, sequencer, or any other MIDI device to exchange data.
Let’s start out by looking at how MIDI works and its various messages.
MIDI Terminals
MIDI messages are sent from one device’s MIDI OUT terminal to another device's MIDI IN terminal
over a MIDI cable. A MIDI message from the WK-1500, for example, could be output through the
WK-1500's MIDI OUT termina! to a connected external device’s MIDI IN terminal over a MID! cable.
Of course, the connected device could send a message back from its out MID! OUT terminal to the
WK-1500's MID! IN terminal over another MIDI cable.

MIDI Channels
MIDI channels, numbered 1 through 16, can be assigned specific parts of the MIDI data. You can
think of them as being similar to the channels on your television. Just as your TV has to be tuned into
Channel 3 to receive broadcasts on that channel, a receiving MiDI device must also be set to the
channel that matches the data it is trying to receive. If it is set to receive Channel 3 MIDI data, for
example, data on ail other channels is ignored.
The WK-1500 can receive data over all 16 MID! channels and can play up to 16 parts, each with its
own individual tone and volume setting. This capability is called “multi-timbre”.
On the receiving side, the WK-1500 can receive keyboard and pitch bend wheel operation data over
any one of the 16 MIDI channels.
