When using a separate keyboard and sound source

When using the sound source of the connected
keyboard :

Keyboard

When the keyboard and sound source used are separate,

the Soft THRU function must be set to ON in order to allow

the MIDI keyboard to simultaneously enter events and play

the sound source.

In order to have the keyboard itself sound, either set the

Soft THRU to OFF or set the Soft THRU to ON and the

keyboard to local OFF.

OSoft THRU On/Off on the SBX-1000

Press! SETUP land select “1. MIDI," then set each port to

Soft THRU from the Soft THRU parameter.

I Song

A song consists of sequence data stored in the built-in

sequencer section of the SBX-1000. The sequence data of

a song is comprised of events in individual tracks and

patterns, and includes other parameters stored with the

song.

A song must be loaded into the sequencer section if it is to

be played by the cue sheet or tempo controller. (o- p.i4,

"Manual 11 (Sequencer)" for details on loading songs)

■ Time Code Rates

There are four different SMPTE time codes corresponding

to the different standards of TV signals.

030 Non-drop

This is an NTSC time code signal system used in

North America and Japan. One second consists

of 30 frames, and one frame consists of 80-bit

digital signals. Since the NTSC system actually

has 29.97 trames/second, a deficit with actual or

absolute

time

(clock)

results.

However,

the

frames of the time code are not dropped since

the continuity of the time code takes precedence

over the deficit with absolute time.

This is called non-drop frame (NDF).

30 Drop

This is the same NTSC signal system as 30

non-drop; however, the time deficit can be

compensated for by dropping or skipping a

frame of the time code at regular intervals. This

system is called drop frame (DF).

This is the system which is used in Europe. One

second consists of 25 frames.

024

This is the system for film. One second consists

of 24 frames.

Setting from the SBX-1000

When the SMPTE sync mode is set to EXT, it is not

neccessary to match the time code of the master tape

with the frame mode. The SBX-1000 automatically

determines the time code type that is received from

the

SMPTE

TIMECODE

terminal

and

sets

operation accordingly.

When the SMPTE sync mode is set to “INT” (internal), the

time code type can be selected.
