APPENDIX

INDEX

Filter: A block which modifies the tone by cutting the output of a specific

frequency portion of the sound. The QY700 has low pass filters

for each element of a voice, allowing the tone to be made more

mellow by cutting the higher overtones, or brighter by allowing

them to pass.

Fingered chord: A function that automatically detects chords based on

the combination of notes that are played on the keyboard, and

converts the playback of patterns or phrases to the chords that

are detected.

Floppy disk: A type of data storage media, available in varieties such as

2DD and 2HD. In order for a device to be able to write and read

data to/from a floppy disk, the disk must be formatted appropri-

ately for that device.

Foot controller: A control device that can be used to control tone, vol-

ume or effects etc. during a performance.

Formatting: The action of initializing a floppy disk so that it can be used

by a specific device.

Gate time: The length of time that a note actually sounds.

GM: A specification approved by the MIDI Standards Committee, stand-

ardizing the basic functionality of a tone generator, and defining

the number of voices and sounds, etc.

Hexadecimal: A system of numbering based on 16, in which the digits

increment in units of n-th powers of 16. The alphabetical charac-

ters A – F are used to express the numbers 10 – 15.

IBM-PC/AT series: This is a type of personal computer manufactured

and sold by the International Business Machine Corporation.

Compatible computers are manufactured and sold by many com-

panies.

Insertion (effect): An effect used in Voice mode as a major factor in the

character of a sound. In Song mode, an insertion effect will ap-

ply only to the specified part (unlike a system effect), meaning

that you can use the insertion effect “aggressively.”

Instrument: One of the individual instruments such as snare or bass drum

that makes up a drum voice. In a drum voice, a different instru-

ment is assigned to each note of the keyboard.

Instrument category: A classification of voice by type of instrument or

playing technique.

Interval time: A delay time that is inserted at regular intervals when

transmitting bulk data that was recorded in a sequence track.

Length: On the QY700 this indicates the number of measures in the

selected phrase.

LFO: An acronym for Low Frequency Oscillator, a block that produces a

signal at a low frequency. The signal from the LFO can be used

to modulate pitch, volume or tone to produce effects such as

vibrato, tremolo and wah.

Load: The process of reading data from floppy disk into internal memory.

Location: The place within a song at which notes will be input or play-

back will be started, indicated as measure, beat, and clock.

Low pass filter: A type of filter which cuts the high frequencies. 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, referring to the lower byte

of data when MIDI control change data is divided into two bytes

for transmission.

Master tune: A parameter that adjust the overall tuning of the entire

device.

Maximum polyphony: The maximum number of notes that can be played

at once. The QY700 can produce 32 simultaneous notes (counted

in 1-element units). If MIDI messages are received requesting

more notes than the maximum polyphony allows, currently sound-

ing notes will be turned off, and the later-received notes will be

played.

MDF2: The product name of a MIDI data filter. This device receives data

for the internal settings of a MIDI device in the form of System

Exclusive messages, and stores them to floppy disk.

Measure: A unit of musical duration consisting of several beats.

MIDI: An acronym for Musical Instruments Digital Interface, a standard

for transferring data between musical instruments. Most elec-

tronic musical instruments today implement the MIDI specifica-

tion and provide MIDI connectors. Such instruments can be con-

nected together to create remote performance or automatic per-

formance systems.

MIDI data filer: A MIDI device that receives data for the internal set-

tings of a MIDI device in the form of System Exclusive mes-

sages, and stores them to floppy disk. An example is the Yamaha

MDF2 MIDI data filer.

Mixer: On the QY700, the display page in which you can make settings

such as voice, pan, effect and volume etc. for the voice of each

part, when recording or playing back.

Modulation wheel: A controller that can be used to smoothly modify

the volume, tone or pitch while you perform.

MSB: An acronym for Most Significant Byte, referring to the upper byte

of data when MIDI control change data is divided into two bytes

for transmission.

Multi-timbral tone generator: A tone generator that can simultaneously

produce more than one type of sound.

Mute: A function that temporarily silences a track or reduces its volume.

Note name: The name which specifies the pitch of a note, expressed as

a character, a sharp or flat symbol, and a number indicating the

octave.

NRPN: An acronym for Non Registered Parameter Number. These are a

type of MIDI control change message, and are used to edit sounds

via MIDI, allowing you to edit filter or EG settings, or adjust the

pitch or level for each instrument of a drum voice.
