G
Gate Time:
The length of time that a note actually
sounds. Longer gate times produce slurred
notes, shorter gate times produce staccato.
GM:
An acronym for General MIDI. A specification
that defines the arrangement of voices in a
tone generator and its MIDI functionality,
ensuring that data can be played back with
substantially the same sounds on any GM-
compatible tone generator.
H
Hexadecimal number:
A system of numbering based on 16, in which
the digits increment in units of n-th powers of
16. The alphabetical characters A-F are used
to express the numbers 10-15. This system
of numbering is used for MIDI data.
I
IBM-PC/AT Series:
A type of personal computer manufactured
and sold by the International Business
Machine Corporation. Compatible computers
are manufactured and sold by many compa-
nies
Insertion (effect):
An effect which can be applied to one spe-
cific part (track). With this effect, you can
apply effects more “aggressively” to your
song. (e.g. rotary speaker effects to organ
sounds, or “wah” effects to guitar sounds.)
Interval time:
A delay time that is inserted at regular inter-
vals of one kilobyte when transmitting sys-
tem exclusive data that was recorded in a
sequence track to tone generators (or exter-
nal MIDI tone generators).
L
LFO:
An acronym for Low Frequency Oscillator, a
block that produces a signal at a low fre-
quency which synthesizers use for the cre-
ation of sound. The signal from the LFO can
be used to modulate pitch, volume or tone to
produce effects such as vibrato, tremolo and
wah.
Location:
The place within a song or pattern at which
notes will be input or playback will be started,
indicated as measure, beat, and clock.
Low Pass Filter:
A type of filter which cuts high frequencies
above a specified point. The sound can be
brightened by raising the cutoff frequency of
the filter, or darkened by lowering it.
LSB:
An acronym for Least Significant Byte, refer-
ring to the lower byte of data when MIDI con-
trol change data is divided into two bytes for
transmission.
M
Maximum Polyphony:
The maximum number of notes that can be
played at once. The QY100 can produce 32
simultaneous notes (counted in 1-element
units). If MIDI messages are received
requesting more notes than the maximum
polyphony allows, currently sounding notes
will be turned off, and the later-received notes
will be played.
Measure:
A unit of musical duration consisting of sev-
eral beats.
Memory Card:
Wafer-thin, high-volume memory cards pro-
vide a convenient way to store and retrieve
QY100 song and style data. Memory cards
that can be used with the QY100 are available
at many electronics and computer stores.
