Midi - Williams Serenade Owner's Manual

Williams Serenade Piano
MIDI stands for Musical Instrument Digital Interface.
This is a world wide standard communication
interface that enables electronic musical instruments
and computers (of all brands) to communicate
with each other so that instructions and other
data can pass between them. This exchange of
information makes it possible to create a system of
MIDI instruments and devices that offer far greater
versatility and control than is available with isolated
instruments. Whether you interface with computers,
sequencers, expanders or other keyboards, your
musical horizons will be greatly enhanced.
MIDI Connection – The MIDI terminals are located
on the left side panel of the piano.
MIDI In – This terminal receives MIDI data from an
external MIDI device.
MIDI Out – This terminal transmits data from this
instrument to other MIDI devices. The transmitted
data includes note and touch velocity produced while
playing on the keyboard, as well as voice changes,
wheel operation, and recorded playback for the
melody tracks. Demo songs and auto accompaniment
are not transmitted.
USB – The USB connector allows you to connect the
piano directly to your computer. It can be connected
without driver installation under the Windows XP,
Windows Vista & MAC OSX environment. The piano
will be recognized as a USB Audio device to receive and
transmit the same MIDI messages described above.
For more information regarding transmitted MIDI
data please see the next page and or the MIDI
implementation chart.

MIDI Channels – The MIDI system in this unit
has 16 channels numbered from 1-16. Each of
the channels is responsible for a voice. When the
instrument receives MIDI data from an external
device, the active channel is determined by the
control message. The transmission channels on this
keyboard are fixed as follows:
Channel 1: Master voice
Channel 2: Layer voice
Channel 3: Split voice
Please see the MIDI Implementation Chart for more
detail.
Note: When a USB cable is connected from the Serenade
to a computer, all MIDI messages will receive/transmit
via USB.
General MIDI Playback Voices
In addition to the 32 Voices selectable from the
control panel, Serenade includes 128 General
MIDI voices that support the Rhythm and Auto
Accompaniment features. These additional sounds
can only be accessed via the MIDI IN jack, or USB
jack (as MIDI input data), corresponding to standard
Program Change numbers.
