Chapter 8 Working in the Editor 55
By default, Enhance Tuning enhances the tuning of notes by moving them to the
closest note in the song’s key. You can limit the enhancement to the notes of the
chromatic scale instead by deselecting the “Limit to key” checkbox.
To enhance the tuning of a Real Instrument track:
1 In the timeline, select the Real Instrument track you want to enhance.
2 Drag the Enhance Tuning slider right to increase the amount of tuning enhancement,
or drag it left to decrease the amount of enhancement.
3 To limit tuning enhancement to the chromatic scale, deselect the “Limit to key”
checkbox below the slider.
You hear the results immediately as the song plays.
Setting the Enhance Tuning slider to higher values can sometimes lead to undesirable
results. Listen carefully to the results of using the slider and set it to the value that
sounds best.
Enhancing the Timing of Real Instrument Tracks
You can enhance the timing of a Real Instrument track. This is especially useful when
you record Real Instrument regions with the right notes, but which are not perfectly in
time with the song.
When you use the Enhance Timing slider, all regions on the selected track (both your
own recordings and loops) are enhanced. You can enhance the timing of single-note,
chordal, and percussion (unpitched) Real Instrument regions. Enhance Timing works
better with regions containing distinct patterns of notes than pads or ambient sounds.
To enhance the timing of a Real Instrument track:
1 In the timeline, select the Real Instrument region you want to enhance.
2 Drag the Enhance Timing slider to the right to increase the amount of timing
enhancement, or drag it left to decrease the amount of enhancement.
If you move the Enhance Timing slider while the song is playing, it may take a moment
for it to “catch up” with the music.
The Enhance Timing slider may not work equally well with all musical material,
especially when set to higher values. Listen carefully to the results of using the slider
and set it to the value that sounds best.
