Glossary
A
Auto Accompaniment (Style playback)
A function that generates pre-programmed rhythm, bass and
chord backing in response to specific notes/chords played (or
received via MIDI).
C
Chorus
One of the Effect types.
Depending on the particular chorus type and parameters, this
can make a voice sound “larger,” as if several identical instru-
ments were playing in unison, or it can give a voice greater
warmth and depth.
Clock
[1]
A unit of note resolution for MIDI Sequence data.
The sequencer determines the playback position of the Song
or Pattern (MIDI sequence data) by using the following three
parameters: Measure, Beat, and Clock.
[2]
Also referred to as “MIDI Clock,” defined as System Real-
time Message in MIDI. This message is transmitted with a
fixed interval (24 times per 1/4 note) to synchronize con-
nected MIDI instruments.
On MIDI Sequencers, you can select whether the instrument’s
internal clock will be used as the Timing Clock, or external
Timing Clock messages received via MIDI IN will be used.
Control Change
A set of MIDI Channel messages that allow for control of a
wide variety of sound parameters, including modulation, pan,
volume, expression, brightness, effect depth, and others.
These can be adjusted using physical controllers, such as the
Modulation Wheel and the Foot Controller.
D
Depth
Refers to the amount or degree to which a parameter setting
changes the original sound.
E
Effect
On the TYROS, an “Effect” is a processing block that alters
the sound output from the tone generator block of the instru-
ment, using DSP (Digital Signal Processing) circuitry to
change the sound in various ways. The TYROS provides two
types of effects: the DSP effects described above (such as
Reverb, Chorus, DSP and DSP variation) and other effects
(such as Harmony/Echo , Initial Touch, Sustain, and Poly/
Mono).
Event List
A useful Song/Style/Multi Pad Creator tool that arranges all
events in a song in chronological order (in measures, beats,
clocks), and allows you to make detailed changes to those
events.
F
Factory Reset
Refers to the original, factory-programmed settings of User
drive memory, loaded to the instrument before it is shipped.
Flash ROM
ROM that can be overwritten allowing you to store your own
original data, unlike conventional ROM.
G
Gate Time
In sequence recording, this determines the actual length of
time a note sounds.
When entering the note events in Step Recording of the MIDI
sequencer, Gate time is determined as a percent value of the
step time. A setting of approximately 50% produces a staccato
sound, values between about 80% and 90% produce normal
note length, and a value of 100% will produce a slur.
L
Left-hand section of the keyboard
The section of keys to the left of the split point. Besides being
used to play the LEFT voice, they can also be used to indicate/
play chords for style playback as well as the Harmony and
Vocal Harmony effects.
LFO
An abbreviation for low frequency oscillator, which generates
a low frequency signal on the tone generator block. The signal
from the LFO can be used to modulate the pitch, filter, and
amplitude. Modulating the pitch produces a vibrato effect,
modulating the filter produces a wah effect, and modulating
the amplitude produces a tremolo effect.
Lower
A keyboard part played on the left side of the keyboard from
the split point for the voices instead of LEFT. This part is not
affected by the on/off status of the [ACMP] button.
N
Note On/Off
MIDI messages which represent notes played on a keyboard
or other instrument. Pressing a key produces a Note On mes-
sage, and a Note Off message is produced when the key is
released.
Note On message includes a specific note number which cor-
responds to the key which is pressed, plus a velocity value
based on how hard the key is struck.
