D-160 Owner's Manual (Before operating the D-160)
38
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.)
