Glossary
Parameter
A factor composing an effect. For example, an initial
reflecting sound is composed of factors such as early
reflection time and early reflection level, while reverberating
sound is composed of pre-delay time and reverberation time.
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 rea! parameter,
and cannot be saved, but it can modify more than two
parameters at once.
Memory
Internal cicuit board for memorization. To obtain the
reverberation 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-R7 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.
Temporary buffer
A space where parameters of effects are stored when
loading or editing. The parameters stored at this buffer
reproduce a corresponding effect.
LOAD
To load means to call up the effect stored in the memory.
When loading starts, parameters in the preset memory
and/or user memory are copied to the temporary buffer,
then new parameters are reflected to digital signal
processing.
Partial loading of the memory is controlled by B.LOAD block
in the editing mode.
EDIT
To edit means to change the value of parameters. You can
create individual effects by changing the parameter values in
the temporary buffer.
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 parameters in the temporary buffer as
part of 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
DPS-R7 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 reverberator to
generate a certain effect inside the internal circuit. Each
effect of reverberation or gated reverberation is provided
with its own operating method. The DPS-R7 incorporates
newly developed algorithm enabling various effects far
beyond any existing reverberator.
