Before Starting

This chapter describes some basic items that you need to know before you start operating the
recorder. 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 recorder.

1. Time Base
2. Recording method and REMAIN indicator
3. Managing songs by Program Change function
4. Real tracks and Additional tracks
5. Input monitoring and playback monitoring
6. Audio file and Event

Time Base

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 recorder 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.

You can switch between these three types
of Time Base to suit your purpose. (Refer
to the explanation in “Display Section” on
page “

20

” for more information on

switching Time Base.)

<Note>

As shown in the figure, the ABS 0 position
(top of the disk) is [-2 bar, 1 beat, 00 clk]
(Time Base-BAR/BEAT/CLK). You can change
this position in the ranged -9 bar to -2 bar
in the “Setting the time signature” menu.
Refer to the “Setting the time signature
menu” section on page “

103

”.
