Time Base - Fostex D-160 Owner's Manual

D-160 Owner's Manual (Before operating the D-160)

6. Time Base

The D-160 indicates the location of the recorder (the current position) using
the ABS time, MTC, or MIDI Bar/Beat/Clock. This time reference is called "Time
Base."
ABS (Absolute Time) refers to an absolute time on the hard disk; MTC (MIDI
timecode) refers to a relative time obtained by adding a certain value (MTC
offset value) to the ABS value; and BAR/BEAT/CLK (bar/ /clock) indicates a
position in a song that corresponds to the MIDI Clock/Song Position pointer and
can be created using the internal Tempo Map. (The following diagram shows
the relationship between the three types of time base.)

BAR =001BAR, "0404(4/4)"
TEMPO=001BAR, 1 "60( =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 time set for the 00
BAR, 1 and 00 CLK positions.)
