Quantizing MIDI and Audio
Quantizing MIDI Event Starts
AudioWarp quantize prevents warp markers from ending up on the same position. If
conflicts occur, only one of the warp markers is quantized. For example, if you use a
quantize value of 1/4 on audio that is based on sixteenth notes, the warp markers at
the quarter-note positions are quantized to the grid, and the remaining warp markers
are moved, keeping the relative distances between the warp markers.
You can also apply AudioWarp quantizing to selection ranges in the Project window
and in the Sample Editor. To avoid moving transient positions that lie outside the
selection range, additional warp markers are created at the closest hitpoint positions
outside the range.
Applying AudioWarp Quantizing
1. Select the audio event that you want to quantize.
2. On the toolbar, activate the “AudioWarp Quantize” button, open the “Quantize
Presets” pop-up menu, and select a preset to determine the quantize grid.
3. Open the Edit menu, and select Quantize.
You can also use the Quantize Panel for applying AudioWarp quantizing. The
Quantize Panel provides more parameters for defining the quantize grid, see
“The
Quantize Panel” on page 136.
Quantizing MIDI Event Starts
If you select MIDI notes in a part and use the Quantize function on the Edit menu, the
MIDI note starts are quantized, that is, the starts of MIDI notes that do not match exact
note positions are moved to the closest grid positions. The grid is set up on the
Quantize pop-up menu. The note lengths are maintained.
Ö If you quantize MIDI parts, all events are quantized, even if none is selected.
Quantizing MIDI Event Lengths
The “Quantize MIDI Event Lengths” function on the Edit menu, Advanced Quantize
submenu, quantizes the lengths of MIDI notes without changing their start positions.
At its most basic level, this function sets the lengths of the notes to the Length
Quantize value on the MIDI editor toolbar by cutting off the note ends.
However, if you have selected the “Quantize Link” option on the “Length Quantize”
pop-up menu, the function resizes the notes according to the quantize grid, taking the
Swing, Tuplet, and Catch Range settings into account.
Quantizing MIDI Event Ends
The “Quantize MIDI Event Ends” function on the Edit menu, Advanced Quantize
submenu, moves the ends of your MIDI notes to the nearest grid positions, taking the
Quantize pop-up menu setting into account.
Quantizing Multiple Audio Tracks (Cubase Only)
You can quantize multiple audio tracks at the same time. To maintain phase
coherence, all tracks have to be sliced at exactly the same start and end positions.
Only then the resulting slices can be quantized without risk of getting phase errors.
Ö For this to work, the audio tracks must reside in the same folder track and the “=”
button for Group Editing must be activated. Furthermore, at least one of the tracks
must contain hitpoints.
