You may sometimes feel that the material you record is lacking in def-
inition or clarity. Also in some cases, there may be excessive volume
differences between loud and soft passages, or it may be difficult to
hear soft sounds that occur simultaneously with loud sounds. For ex-
ample when recording your band performance, there might be an ex-
cessive difference in volume between the intro and the break. Or when
recording conversation, there will be a difference in volume between
someone near the mic and someone farther from the mic.
The Mastering effect processes such sounds to give them better defini-
tion and a more consistent volume.
You can also use this to enhance the playback of material you've al-
ready recorded on the R-1, or to enhance material as you're recording
it into the R-1 from media such as cassette tape.
Internally, this combines an enhancer and a two-band (low and high)
compressor.
This effect cancels the sounds that are located at the center of a stereo-
recorded song. You can use this to remove the vocal from a song, leav-
ing only the accompaniment. However this will not be as effective if
special effects have been used to create a broader stereo field or if the
recording contains a large amount of reverberation.
The tuner is a useful tool for use with a musical instrument; it is not an
"effect" that modifies the original sound. This produces a sine wave of
a fixed pitch at the notes C, D, E, ... relative to A=440 Hz. You can use
this reference pitch when tuning your musical instrument.
Internally, this is a fixed-pitch oscillator. Even if you record while the
tuner is sounding, the sound of the tuner will not be recorded.
The metronome is a useful tool for use with a musical instrument; it is
not an "effect" that modifies the original sound. You can specify the
time signature and the tempo of the metronome.
Even if you record while the metronome is sounding, the sound of the
metronome will not be recorded.
