Glossary Performance In the MU100R, "Performance" refers to an operation mode and the programs that are used in that mode. A Performance can contain up to four different Parts, all controllable over the same MIDI channel. The preset Performances of the MU100R are special multi-Part sound programs designed particularly for live performance and studio recording purposes. Pitch Bend A function found on virtually all MIDI keyboards (usually controlled with a pitch bend wheel) that allows the pitch to be raised or lowered continously. The Pitch Bend Control parameter on the MU100R allows you to set the range over which the pitch can be changed. polyphony The number of notes that can be sounded simultaneously by an electronic instrument. The MU100R has 64-note polyphony, ensuring that even the most complex song data will play back completely and accurately, with no "note robbing." port To answer the need for more MIDI channels (the limit is 16), many MIDI interfaces offer two or more MIDI ports, each of which can address 16 MIDI channels. The MU100R is equipped with two independent MIDI ports (A and B), providing 32-channel operation. The two ports are also addressable via the TO HOST computer interface. Portamento A function found on early synthesizers that creates a continuous pitch glide between successively played notes. On the MU100R, the time of the pitch glide can be adjusted. Solo The Solo function of the MU100R allows you to isolate a single Part, to hear how that Part sounds by itself. Sound Module mode The MU100R has four Sound Module modes, and these determine the basic operation of the unit as a tone generator. Three Multi modes (XG, TG300B and C/M) and one Performance mode (PFM) are available. tone generator An electronic instrument that functions as a MIDI-controllable sound source. For the most part, the term "tone generator" refers to those devices that have no keyboard or other controller, but are meant to be connected to and played from a separate keyboard or computer. Variation In the MU100R, "Variation" refers to the special section of various effects, including Reverb, Delay, Chorus, and many others. The Variation effects total 70, and can be used simultaneously with the other effect sections of the MU100R: Reverb, Chorus, Insertion 1, 2 Harmony Effect and EQ. velocity The speed at which a note is played (for example, on a keyboard). Normally, the faster (or harder) a key is struck, the higher the corresponding note's velocity - and, hence, the louder the sound produced. The MU100R features a variety of velocity-related parameters that provide extensive control over the velocity response of the Voices, and even allow you to set up sophisticated velocity splits, in which the Voices change in response to playing velocity. return Related to effect operation, "return" refers to the effect-processed signal that is returned to the overall sound mix. For example, the parameter Reverb Return determines the amount of Reverb-processed signal that is blended with the overall sound mix of the MU100R. ("Return" is the companion function of "send" below.) send Related to effect operation, "send" refers to the signal that is sent to an effect for processing. For example, the parameter Reverb Send determines the degree to which an individual Part is processed with the Reverb effect. ("Send" is the companion function of "return" above.) sequencer A device used for recording, editing and playing back of MIDI data. Sequencers are generally of two types: "dedicated" sequencer units, and computer-based sequencing software. The MU100R can be used with either type. Vibrato Vibrato is a quavering, vibrating sound, and is produced in the MU100R by regularly modulating the pitch of a Voice. The speed and depth of the Vibrato can be adjusted, as well as the time it takes before the Vibrato effect is applied. Voice The basic sound unit (or sound program) of the MU100R. There are a total of 1523 Voices available on the MU100R. XG-MIDI An abbreviation for Extended General MIDI, a new standard created by Yamaha which significantly improves on the General MIDI standard by providing a greater variety of high-quality Voices and enhanced effect operation. 184 Appendix
