Maximum Polyphony:
The maximum number of notes that can be
played at once. The QY70 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
several beats.
MIDI:
An acronym for Musical Instruments Digital
Interface, a standard for transferring data
between musical instruments. Most
electronic musical instruments today
implement the MIDI specification and
provide MIDI connectors. Such instruments
can be easily connected together to create
remote performance or automatic perfor-
mance systems.
MIDI Data Filer:
A MIDI device that receives bulk data for the
internal settings of a MIDI device in the form
of System Exclusive messages, and stores
them to disk. An example is the Yamaha
MDF2 MIDI data filer.
Mixer:
On the QY70, the display page in which you
can make settings such as, pan, volume, etc.
for the voice of each song or pattern track,
when playing back.
Modulation:
A function that can be used to change the
volume, tone, or pitch cyclically while you
perform. On the QY70, you can apply
modulation by holding the [OCT UP] key
while playing a note on the micro keyboard.
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 voice.
Mute:
A function that temporarily silences the
specified track or reduces its volume.
N
NRPN:
An acronym for Non Registered Parameter

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.
O
On-bass:
A function that lets you specify a root note
for the bass independently of the chord, so
that the playback of a bass phrase whose
Phrase Type is Bass will be fixed on that root
note.
Overdub:
A method of real-time recording in which
new material is recorded without erasing
previously recorded tracks.
P
Pan:
The parameter that sets the stereo location
of a sound when it is played back in stereo.
(“Pan” or “panpot” are abbreviations of
“panoramic potentiometer”.)
