Roland SBX-1000 - Manual (Page 10)

Press [SMPTE I, and select the type in the “Frame Mode”
field.
ITime Sign TEMPO
This indicates the time signature of a measure when
executing manual tempo control with the tempo controller or
when making tempo programs. A value of “4/4” indicates a
time signature of 4/4 and “3/4” indicates a time signature of
3/4.
■ Check Sum
Roland's exclusive messages contain check sum data
immediately before the End Of Exclusive messsage (F7).
The last 7 bits of the sum of the address, size and check
sum become zero. The SBX-1000 automatically calculates
the check sum.
o- P.36, “Manual I ” for information on exclusive
events in the cue sheet.
P.72, “Manual II (Sequencer)” for information on
exclusive events in the sequencer.
I Channel Aftertouch Data
(o- “Aftertouch”)
I Tune Request Data IS'liai
This message is used to automatically tune the overall pitch
of an analog-type sound source (synthesizer). Whether this
message is actually recognized by the device and. If
recognized, what frequency the device is tuned to, depends
on the specifications of the device itself.
■ Disk Format
Before a newly purchased disk (or a disk that has been
used by another device)can be used in the SBX-1000, it
must be formatted as an SBX-1000 disk.
If you wish, you can save the System program when
formatting a disk, to create a System disk. It is also possible
to format a disk without the system program, for the sole
purpose of storing data.
When the format operation is executed, all existing data on
the disk will be erased. It is not possible to recover the
original data from a formatted disk.
■ Duration IWiJil
Duration is the length of time that elapses (in a note event
that is registered in the cue sheet) from the pressing of the
key until the key is released. It is expressed in standard
timecode from (hours, minutes, seconds and frames). The
value can be edited after recording.
■ Tempo
Tempo is expressed as the number of quarter notes played
in one minute.
Tempo = 60
(60 quarter notes in one minute)
■ Tempo Controller
The SBX-1000 can control the tempo of a connected
sequencer or rhythm machine by transmitting MIDI sync
data (specifically, MIDI timing clock messages) from the
MIDI OUT terminal. In combination with the SMPTE time
code functions of the SBX-1000, this makes it possible to
synchronize SMPTE devices with MIDI devices, allowing
you, for example, to synchronize video tape decks and
muititrack tape recorders with MIDI sequencers. The tempo
controller is used to control these operations.
There are three methods of control: manual, original and
program.
■ Tempo Change Event
The tempo of the song is determined by the standard
tempo; however, in order to change the tempo in the middle
of a song, you can enter a tempo change event in the
tempo track. The tempo change evented is enter as a
numeric value, but the ratio of the standard tempo is stored
internally. In this way, the overall tempo becomes faster or
slower by changing the standard tempo.
Tempo change events are entered via step input, (o- p,35,
“Manual II for the sequencer”) Tempo change events
cannot be entered in real time.
