Before Starting; Time Base - Fostex VR800 Owner's Manual

VR800 Owner's Manual (Before Starting)
This chapter describes some basic items that you need to know before you start operating the VR800.
All users, including those who are familiar with using tape-based multitrackers and those who are new to
multitrackers, should read this chapter thoroughly to understand the functions of the VR800.
The word "Time Base" appears frequently in this manual. The concept of Time Base is similar to a "tape counter"
on a conventional tape-based multitracker in that it indicates the precise position of the recorder transport
section (the current position).
The VR800 offers three types of Time Base: ABS (Absolute type), MTC (MIDI time code), and BAR/BEAT/CLK (bar/
beat/clock). ABS indicates an absolute time on the disk. MTC indicates a relative time that is obtained by adding
a certain value (MTC offset value) to the ABS value. BAR/BEAT/CLK indicates the position in a song created in the
internal Tempo Map according to MIDI clock and Song Position Pointer. The following diagrams depict the
relationship among these three types of the Time Base.
BAR/BEAT/CLK
BAR = 001BAR, 0404
TEMPO=001BAR, 1 , 60
MTC OFFSET=01H, 00M, 00S, 00F
MTC OFFSET MODE=ABS
(This shall be assumed to be the
MTC OFFSET time set for the ABS
00M, 00S, and 00F positions.)
MTC OFFSET=01H, 00M, 00S, 00F
MTC OFFSET MODE=BAR
(This shall be assumed to be the MTC
OFFSET time set for the 00 BAR, 1
and 00 CLK positions.)
You can switch between these three types of Time Base
to suit your purpose. (Refer to the explanation in "Display
Section" on page "17" for more information on switching

Time Base.)
