TIME BASE
The term “Time Base” frequently appears in the text
of this manual. The time base plays the same role as
the “tape counter” of conventional tape recorders, and
is used to show the location of the recorder.
There are 3 types of time bases:
1. ABS (Absolute Time) indication
2. BAR/BEAT/CLK (Bar, Beat, Clock) indication
3. MTC (MIDI Time Code)
The user can switch between time bases by pressing
the [DISP SEL/
TIME BASE] key, while the [SHIFT] key is
depressed.
An ABS (Absolute Time) base is the “absolute time” of
the hard disk. A time base counter between 00H 00M
00S (ABS 0) and 23H 59M 59S is created when
creating a program. According to the following figure,
the recorder is located at a 00M (minute) 00S (second)
ABS point. The H (hour) appears when the ABS exceeds
the one hour mark.
ABS 0 is the universal standard point to manage the
recorder location, and correlates with other time
bases.
BAR/BEAT/CLK indicate the “Bar, Beat, Clock” that are
created with the tempo map (beat and tempo) of the
VF-16.
According to the following figure, the recorder is
located at -002BAR (Bar 2) 1BEAT (Beat 1) of the BAR/
BEAT/CLK.
BAR/BEAT/CLK set the ABS 0 location as Bar -002 as
the offset position.
The location of the bar thereafter is determined
according to the beat and tempo setting.
The default setting of ABS 0 is set at Bar -002, however,
this setting is variable between Bars -009 and -002.
MTC set the ABS 0 location to MTC ** H** M**S. In other
words, MTC sets the time base to start MTC from a
certain time, which serves as the offset time, to
synchronize the following 24 hour MTC time base with
the ABS to count the time. If, for example, ABS 0 is set
to MTC 1H, then MTC starts from 1H and ABS 1H (one
hour elapsed) will be MTC 2H.
The MTC time set as ABS 0 is called the “MTC Offset”.
According to the figure below, the current location of
the recorder is at MTC 00H (hour), 59M (minutes), 57S
(seconds).
The default setting of the MTC offset is set to 00H 59M
57S 00F 00SF. This time base can be changed to any
24 hour clock.
It is also possible to change the setting to Bar 001 and
Beat 1 of BAR/BEAT/CLK, instead of using the ABS 0
location point.
The following illustrates the relationship between the
3 time bases.
