Sony DPS-D7 - Glossary

Glossary
Parameter
A factor composing an effect.
For example, a
delayed effect
is composed of
factors such
as
delay time
and delay level.
The value of each of these
factors is called the
parameter
and is critical to one solid
effect.
Secondary parameter
A parameter capable of
modifying parameters
while editing
under
a
certain rule, scale
and sync are secondary
parameters. A secondary
parameter is not
a
real parameter,
and cannot be saved, but
it can modify more
than two
parameters
at
once.
Memory
Internal
cicuit
board for memorization. To
obtain the
delayed
effect, the micro computer
residing in the unit sends
parameters to the
signal processing LSI (DSP).
You can
save these parameters in a
memory and call it up
when
necessary. The
memory of the DPS-D7
provides the preset
memory for a hundred
kinds of effect (preset
upon shipment)
and user
memory (accessible freely by a
user) for up to 256
effects.
EDIT
To edit means to change the value
of parameters.
You can
create individual effects by
changing the parameter
values.
The EDIT function allows you to
improve effects
in the
preset memory as you
desire for the operating
condition or
your
particular
needs.
SAVE
To
save is to
store the
parameter in the
user memory. This is
a
significant
function for
maintaining
the individual
effects.
Once the
individual effect is saved,
it can be
called anytime
for editing
and/or saving
for the second
time.
MIDI
MIDI stands
for Musical
Instrument
Digital Interface,
a
universal
standard unit
for the data
communication among
electronic
instruments. A
keyboard
controlling other
electronic
instruments, a
sequencer
or
a
PC organizes
automatic playing.
The MIDI
function
incorporated in the
DSP-D7
allows you to select
the
memory number through
the MIDI
program change
number
(timbre changing
signal for
the
keyboard), or to
control parameters
with the
MIDI control
change signal
(variation of
modulation wheels).
Algorithm
An operating
method required
for the
digital delay to
generate a
certain effect inside
the internal
circuit. Each
effect of
feedback delay, tap
delay, long
delay is provided
with its own
operating method.
The DPS-D7
incorporates
newly developed
algorithm
enabling various
effects far
beyond
any existing delay
unit.
