Offset
Normally, the resolution grid is aligned evenly with the start of measures and
beats. As an option, you can shift the grid earlier or later by any desired number of
clock ticks. If the resolution is a quarter note and you’ve set the offset to +3 ticks,
then a note that is originally near 1:01:000 would be moved to 1:01:003—three
ticks beyond the beat boundary.
Duration
As an option, SONAR can adjust the duration of note events so that each note ends
one clock tick before the start of the nearest resolution-sized note. This ensures
that the notes do not overlap, which can cause problems on some synthesizers. The
adjustment may lengthen the duration of some notes and shorten the duration of
others.
When you use Groove Quantize, the duration adjustment compares the note
length to the duration of the sample note in the groove. If no duration information
is available, SONAR uses the distance to the start of the groove event closest to the
end of the note.
Velocity
The velocity adjustment, which is only available with the Groove Quantize
command, adjusts the note velocity to the velocity of the corresponding notes in the
groove.
Strength
The human ear is tuned to the slight “imperfections” we hear from most
musicians. If you quantize a project so that all notes are perfectly in position, it
may end up sounding mechanical or rigid. To avoid this, SONAR lets you adjust
the strength of the adjustment. A strength of 100 percent indicates that all notes
are moved so that they are in perfect time, while a strength of 50 percent means
that all notes are moved half-way towards the desired position. This lets you
“tighten up” the timing as much as you want, without going too far.
The Groove Quantize command also lets you control the strength of duration and
velocity adjustments. As you work with this command, you will notice that the
note start time has a greater effect than the duration on the rhythmic feel of the
track. For this reason, changing the starting times (time strength close to 100
percent) has a more noticeable effect than changing durations (duration strength
close to 100 percent). However, there are situations in which you might want to
change both to avoid ending up with notes that overlap or with unwanted rests.
