A p p e n d i x M 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 performance 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 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. 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".) Parameter: A setting or data item which you can modify in the various mode and sub-mode displays. 238
