MIDI
The Musical Instrument Digital Interface
(MIDI) is an industry-standard protocol that
enables electronic musical instruments such
as keyboards, computers, drum machines,etc.
to communicate, control, and synchronize
with each other. MIDI transmissions consist of
electronic codes that communicate notes to be
played, the instrument, pitch or intensity that
notes are to be played with, and controlling
codes such as volume, vibrato, cues and clock
signals. The Rhapsody III has several functions
that facilitate its use as a MIDI device or
controller.
MIDI Channels
The Rhapsody III has 16 channels numbered
from 1-16. Each of the channels is responsible
for a voice. When the instrument receives MIDI
information from an external device, the active
channel is determined by the control message.
The transmission channels are fixed as follows:
Channel 1 - Master voice (keyboard)
Channel 2 - Split voice (keyboard)
Channel 3 - Layer voice (keyboard)
Local On/Off
Turning the Local On/Off function to “Off” will
disconnect the keyboard from the internal sound
engine of the piano. The Rhapsody III may then
be used as a MIDI controller to control other MIDI
devices or virtual instrument software running on
a computer, without playing the sounds on the
piano. Additionally, it may be desirable to turn
local playing off for other requirements such as
when using MIDI sequencing software on your
computer.
Local On/Off Setting
1. Press and hold the Function button.
2. Press the D#1 key. When D#1 is first pressed
the current setting is confirmed by the piano
playing a C3 note once for on and twice
for off. Pressing D#1 again will change the
setting playing a C3 note the amount of times
equivalent to the new setting.
Multitimbral Mode
The Rhapsody III is able to receive
MIDI information on up to 16 channels
simultaneously. If you plan to use your piano
with a multitrack MIDI recording system, you
can record up to 16 different parts using the
Williams Rhapsody voices, each played back
individually on different MIDI channels. To
ensure your recorded part is played back with
the correct voice make sure to press the voice
button first and play your part second.
NOTE: Because the Rhapsody is receiving
playback information via MIDI, the currently
selected voice on the piano may not correspond
to the voice being played back.
MIDI Channel Modes
1. Press and hold the Function button.
2. Pressing A#0 allows you to change the MIDI
channel. The main piano sound will play
Piano 1 C3 the amount of times equivalent
to the current value. So, if MIDI channel 5 is
selected it will play 5 times. You then press
A#0 five times to select channel 10. Piano 1
C3 will play the amount of times equivalent
to the current setting, after 2 seconds of
inactivity. Once 16 is reached, pressing one
more time will select 1.
MIDI Panic Reset
1. Press and hold the Function button.
2. Pressing C#1 triggers “MIDI Panic” which
sends out general MIDI reset messages such
as all note off, etc. Once Panic reset has
been completed, the piano will automatically
exit Edit mode.
Memory Autosave
When modifying the settings of the Williams
Rhapsody III the following settings will be saved
after you turn off the keyboard: Reverb, Chorus,
ModFX (for each voice), Main Volume, Layer
Volume, Split Point, Split Volume, MIDI Channel,
Velocity Curve, Split Octave, and Auto Power Off.
