Changing the Timing of a Recording
matches the smallest note in the region you are quantizing. If you are
quantizing a run of sixteenth notes, use a sixteenth note as the resolution. If
you are quantizing a mix of sixteenth and eighth notes, you should still use
a sixteenth note. At the default timebase of 480 PPQ, 480 clock ticks is
equal to quarter-note resolution.
When you use Groove Quantize, SONAR creates a grid at the desired
resolution on top of the notes in the groove. For example, if the groove
contains only quarter notes but you choose sixteenth-note resolution,
SONAR builds the grid by dividing the space between each quarter note
into four equal sections. In places where the groove file contains no notes,
SONAR builds a fixed grid of the desired resolution.
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
