Basic Features of VF80EX

Trim

It is important to set the analog input level appropri- ately when converting an analog input signal from [INPUT] A or B into a digital signal (A/D conversion). You can adjust the analog level using the [TRIM] con- trol. The [PEAK] indicator lights if the level is too high.

If the [TRIM] setting is not appropriate and the ana- log input level is too high (if the PEAK indicator lights), the signal will be converted into a distorted digital signal, resulting digital noise. You cannot eliminate this distortion/noise from the sound in the following stages. Therefore, be sure to adjust the level appro- priately using the [TRIM] knob not to light the [PEAK] indicator when receiving the loudest audio input sig- nal.

Time Base

The term "Time base" frequently appears in this manual. The time base is used to show the location in the recorder, like the "tape counter" of conventional tape recorders.

There are three types of time bases:

1.ABS (Absolute time)

2.Bar/Beat/Clk (Bar/Beat/Clock)

3.MTC (MIDI Time Code)

You can switch between these time bases by pressing the [TIME BASE SEL] key.

The ABS shows the absolute time of each program and is striped from 00h 00m 00s (=ABS 0) to 23h 59m 59s when a program is created.

The example below shows the current recorder posi- tion is at 00m (minute) 00s (second) 00f (frame). The hour digit appears only when the ABS time ex- ceeds 01h 00m 00s 00f.

ABS 0 is the reference position for managing all the location and related to other time bases.

Bar/Beat/Clk shows the musical position generated from the internal tempo map of the VF80EX (includ- ing time signature and tempo).

The example below shows the current recorder posi- tion is at beat 1 of bar -2.

This position (beat 1 of bar -2) corresponds to ABS 0 and the following bar/beat numbers are determined according to the time signature and tempo settings.

Beat 1 of bar -2 corresponds to ABS 0 as the default setting, however, you can change to set it between bar -9 and bar -2.

MTC (MIDI Time Code) runs in sync with the ABS time. The MTC value (**h **m **s) corresponding to ABS 0 can be set, which is called "MTC offset".

If you set the MTC offset to 01h 00m 00s, the MTC will start from 01h 00m 00s, and at the ABS 00h 00m 00s position, the MTC value will be 02h 00m 00s

The example below shows that the current position is at MTC 00h 59m 57s

The default MTC offset is 00h 59m 57s 00f 00sf. You can change the offset to any time value of 24-hour clock.

It is also possible to set the MTC offset by setting the MTC value corresponding to "beat 1 of bar 1" instead of "ABS 0".

The following diagram illustrates the relationship between the three time bases.
