Before Starting

This chapter describes some basic items that you need to know before you start operating the FD-8.

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 FD-8.

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.Signal flow (The PAN knob function and Stereo Bus)

7.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 FD-8 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.

ABS 0
00M, 00S, 00F	00M, 08S, 00F	REC END

ABS

DISK END 23H, 59M, 59S

BAR/BEAT/CLK

BAR = 001BAR, 0404

TEMPO=001BAR, 1 , 60

MTC

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.

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.)

Note: When BAR/BEAT/CLK is selected as Time Base, the position for ABS 0 (top of the disk) is always “-2 BAR, 1 , 00 CLK” and you cannot modify this value.
