Feedback Delay; Feedback Level; Flash Memory - Roland VM-C7100 Owner's Manual

Glossary
Effects
Special processes that modify or enhance the sound in some way,
such as causing it to distort, adding reverberation, or delaying it,
etc. Also used to refer to the device or processor that produces the
effect. On this system, effects may be abbreviated as FX.
Enhancer
An effect that adds sparkle to the sound by emphasizing the high-
frequency overtones. It can be used when you wish to give the
sound more definition and make it stand out, while not changing
the tone or balance. It is effective when applied to vocals.
Equalizer
A device that modifies the tone by boosting or cutting the level of
the sound in a specific frequency range. Abbreviated as "EQ." On
this system, a graphic equalizer is provided as one of the effect
algorithms. Parametric equalizers are also provided on the input of
each channel/track, and also within some effect algorithms.

Erase
A function that erases a specified range of automix data. At this
time, the area that was erased will become blank.
Error message
A message that appears in the display when an incorrect operation
has been performed, or when data could not be processed correctly.
Event
On this system, this refers to each individual piece of data recorded
by the auto-mix function, such as volume, pan, or scene.
Automix
Expand
A function that broadens the range of change in data values within
a specified region of the automix, so that data above a specified
value (Threshold) is increased to a higher value, and data below
that value is decreased to a lower value.
Expander
An effect that increases (by a fixed ratio) the difference in loud and
soft volume levels, by making low-level signals softer, and high-
level signals louder.
EZ (easy) naming
A function that allows you to quickly and easily select from a list of
previously prepared project or scene names etc. (such as "Guitar-1"
or "Gt1"), instead of using buttons to input characters one by one.
EZ (easy) routing
A group of functions that allows internal connections to be changed
instantly for a specific application, such as a live performance or
recording. On this system, there are two such functions; Template
which allows you to select and recall a previously connection
pattern, and Virtual Patchbay which allows you to connect lines
on the screen to change the input/output jack assignments.
Factory reset
A function that restores all settings of a device to their factory
values.

Fade-in
Fade-out
Fade-in means to gradually raise the volume (for example, at the
beginning of a song). Fade-out means to gradually lower the
volume until silence is reached.
Fader
Faders are the sliders that are arranged on the panel of the console,
and used mainly to adjust the volume.
Feedback
In the context of an audio circuit, this refers to the process of
returning a portion of a signal back to the input.

Feedback delay

A delay that is provided on each input channel of this system, and
can be used to produce echo effects or comb filter effects. High
(low) frequency damp settings are provided, allowing analog-style
echo to be produced.

Comb filter

Feedback level

The action of returning part of an output back to the input is called
Feedback. The amount that is returned to the input is the Feedback
Level. Increasing this will increase the number of times that a delay
is repeated, or will make a chorus effect sound richer. However if
the feedback level is increased excessively, oscillation can occur,
and unwanted sounds can be generated.
Filter
A device or function that cuts a portion of the frequency bandwidth
to modify the tone. There are various types of filter, such as the Low
Pass Filter which passes only the portion that is lower than a
specified frequency (the cutoff frequency), or the High Pass Filter
which passes only the portion that is higher. Some filters are able to
vary the cutoff frequency over time according to a pre-determined
pattern.
Flanger
An effect that produces a metallic modulation that resembles the
sound of a jet plane taking off and landing. It is produced in a way
similar to delay or chorus effects, by adding a slightly time-delayed
sound to the input.

Flash memory

A type of memory that can maintain its data without a backup
power source such as a battery. Its data can be electrically rewritten
from outside. Flash memory is suitable for storing various types of
data that must be maintained even when the power is off, or for
containing the system software of a device. Since the data can be
rewritten electrically, it is easy to update the system software of a
device. However since it normally operates as ROM (read-only
memory), it is not suitable for applications that require the contents
to be erased or rewritten at high speed. In this system, flash
memory is used in the area that holds the system software and the
libraries. Flash memory is also used in the memory cards
(SmartMedia) that are used for external backup etc.
