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 record-
ing 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 com-
pletely 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 inde-
pendent MIDI ports (A and B), providing 32-chan-
nel 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 suc-
cessively played notes. On the MU100R, the time
of the pitch glide can be adjusted.
return Related to effect operation, "return" refers to
the effect-processed signal that is returned to the
overall sound mix. For example, the parameter Re-
verb Return determines the amount of Reverb-pro-
cessed 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 func-
tion of "return" above.)
sequencer A device used for recording, editing and
playing back of MIDI data. Sequencers are gener-
ally of two types: "dedicated" sequencer units, and
computer-based sequencing software. The MU100R
can be used with either type.

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 op-
eration of the unit as a tone generator. Three Multi
modes (XG, TG300B and C/M) and one Perfor-
mance mode (PFM) are available.
tone generator An electronic instrument that func-
tions 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 ef-
fects 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 ex-
ample, on a keyboard). Normally, the faster (or
harder) a key is struck, the higher the correspond-
ing note's velocity — and, hence, the louder the
sound produced. The MU100R features a variety
of velocity-related parameters that provide exten-
sive 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.
Vibrato Vibrato is a quavering, vibrating sound, and
is produced in the MU100R by regularly modulat-
ing 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 avail-
able on the MU100R.
XG-MIDI An abbreviation for Extended General
MIDI, a new standard created by Yamaha which sig-
nificantly improves on the General MIDI standard
by providing a greater variety of high-quality Voices
and enhanced effect operation.
