Fostex VF160EX operation manual Time Base

*When pressing the [BUSS-SOURCE] key, the status will require selection of a channel to send to “REC BUSS”, as mentioned earlier. Therefore, the channel in which the [CH STATUS/CH SEL] key is pressed is sent to the “REC BUSS”.

All channels are selected up to this point. The following two types only select tracks.

*It is possible to select the track to record (REC READY) in each respective REC mode by pressing the [BUSS-RECTRK] key and [DIRECT-REC TRK] key.

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

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.

ABS 0

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 VF160. 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.
