334 RS7000

A

Aftertouch
MIDI messages which are transmitted when additional
pressure is applied to the keyboard after notes are
played.
Amplitude Envelope
A curve that denes the amplitude variation of a note
from the time it is initially played (attack) until it fades
away completely (release).
Arpeggio
Sometimes known as broken chords, the notes of a
chord are played one-after-another rather than all at
once. The RS7000 auto arpeggio feature automatically
creates a variety of arpeggios based on notes you play
on the keyboard.
AWM2 Tone Generation
A method of generating sound developed by YAMAHA
which is based on digitally recorded waveforms. Since it
generates the complex waveform of actual acoustic
instruments, it provides extremely realistic sounds. Digi-
tal ltering is also built-in, allowing precise control over
the tone. AWM2 is an acronym for Advanced Wave
Memory 2.

B

Bank Number
In the RS7000 use of the bank select MSB and LSB is
facilitated by categorizing voices according to bank
number.
Bank Select
MIDI data used to select extended voices. Control num-
ber 0 (MSB) and 32 (LSB) as used together to select
voice banks. Actual voice selection is achieved by trans-
mitting the bank select value in combination with the
appropriate program change number.
Beat
When playing back or recording a song, one beat (a
rhythmic subdivision of a measure).
BPM (Beats Per Minute)
Another term for tempo, determining the speed of
playback.
BPM Track
A sequencer track dedicated to the recording and play-
back of BPM changes.
Breakbeats
Originally this term referred to a section of a song in
which all other instruments stop playing while only the
drums maintain the rhythm. In dance music such drum
phrases are often sampled and looped to provide the
rhythmic foundation for a new piece of music. Generally,
a drum pattern of a few measures in length is referred to
as a breakbeat.
Brilliance
A control or parameter that regulates the brightness of
the tone. The cutoff frequency of the RS7000 lters can
be controlled to adjust the brilliance.
Buffer
A memory area used for temporary data storage.
Bulk Data
A type of System Exclusive message which consists of
data for the internal settings of a device.
Bus line
A route (line) that carries audio signals between stages
of a sound system. The bus lines of the RS7000 include
SEND VAR. TO DELAY, SEND VAR. TO REVERB,
SEND DELAY TO REVERB, and the stereo bus line
that collects the stereo output of each stage.
Byte
A group of 8 digital bits is generally referred to as a
byte. A single byte can be represented by a 2-digit
hexadecimal number. This type of notation is used to
represent MIDI data, memory capacity, and other digital
values.
