Playing the Internal Sound Generator
About the internal sound generator
The SC-D70 contains a GS/GM2 compatible sound generator equivalent to that of
the SC-8820, providing a diverse and high-quality array of 1608 sounds and 63 drum
sets. It also has four sound maps, which provide the same sounds as the SC-8820, SC-
88 and SC-88Pro, and SC-55/55mkII. This allows the SC-D70 to meet a wide range
of your sound needs for song creation, and allows it to play back music data created
for earlier models.
It also provides a rich assortment of effects processing capability: 64 different
insertion effects, 8 kinds of reverb, 8 kinds of chorus, 10 kinds of delay, and a two-
band equalizer.
Parts and sounds
The SC-D70 is able to play 32 different sounds simultaneously. (However, only when
connected via USB.) A sound generator such as the SC-D70 that is able to play
multiple sound simultaneously is referred to as a multitimbral sound generator.
The term “timbre” means “sound” or “tone.” Since 32 different sounds can be
produced simultaneously, this means that (if we use the analogy of an orchestra), the
SC-D70 can play an ensemble of 32 musical parts. The sound played by each part of
the SC-D70 is called an instrument (An instrument list is provided on p. 58.) You can
create an ensemble by assigning the desired sound to each of the 32 parts.
■ Different types of parts
The SC-D70 has 32 parts, A01–A16 and B01–B16, organized into groups A and B with
a number from 01 to 16. Each part can be set either as a normal part or as a drum
part. Normal parts are used to play melody or bass. Drum parts are used to play
percussive instruments. The distinction between these two types is called the part
mode.
By default, the parts are set to the following part modes.
Normal part: A01–A09, A11–A16, B01–B09, B11–B16
Drum part: A10, B10
■ Which part receives the MIDI IN data?
In MIDI mode (p. 39) when using the MIDI connector to play the SC-D70, group A
is assigned to MIDI IN. In other words, the MIDI messages received at MIDI IN are
sent to group A parts. For example, a MIDI message received at MIDI IN on channel
5 will play group A part 5 (A05) (at the default settings). When using the MIDI IN
connector to play the SC-D70, it is not possible to play group B parts.
■ Selecting a part
First select a part, and then select the sound for that part.
1. Make sure that the PART sound generator indicator is lit.
If it is not lit, press [PART].
In this state, the display window will show the part number.
2. Press [INC] or [DEC] to select the part.
The part indication in the display window will change in the range of A01–A16 and
B01–B16.
You can change the part
mode of each part. For
details refer to Part Mode
(“Appendix” on the
accompanying CD-ROM).
To change the
correspondence between
parts and MIDI channels,
send the Rx. CHANNEL
System Exclusive message
via MIDI. (Refer to
“Appendix” on the
accompanying CD-ROM.)
