13.23 量化MIDI数据

The term Quantize refers to a process of aligning a set of musical notes to a precise setting. This results in notes being set on notes and on exact fractions of notes. When you quantize a group of MIDI notes, the program moves each note to the closest point on the timing grid.
术语“量化”,是指将一组音符与精确设置对齐的过程。这会导致针对音符设置音符,并针对精确的音符分数设置音符。当您量化一组MIDI音符时,程序会将每个音符移动到时间网格上最近的点。
The point of quantizing is to provide a more uniform timing of sounds. It is often applied to MIDI notes created by a musical keyboard or drum machine. Quantize is available by choosing the Edit, Quantize events command from the MIDI Editor menu. This causes the dialog box shown on the right to be displayed.
量化的目的是提供更统一的声音时间信息。它通常用于由音乐键盘或鼓机创作的MIDI音符。从MIDI编辑器菜单中选择“编辑”--“量化事件”命令,即可使用量化。这会导致显示右侧所示的对话框。
The first choice you have is between the Use Grid and Manual Settings option. We'll come to Use Grid shortly.
您可以选择的第一个选项是“使用网格”和“手动”设置。我们很快就会开始使用网格。
Shown right is the dialog box interface that appears when the Manual option is selected. The various quantize parameters are explained below.
右侧显示的是选中“手动”选项时出现的对话框界面。下面解释各种量化参数。
Notice the Bypass option (top right). Disabled it lets you see the result of different quantize parameter settings as you tweak them. Enable this until you are finished if you don't want this to happen. Toggle it to compare how your music sounds with and without quantizing applied.
请注意“旁通”选项(右上角)。禁用该选项后,可以在调整量化参数时查看不同量化参数设置的结果。如果您不希望发生这种情况,请在完成之前启用此选项。切换它以比较应用量化和不应用量化时的音乐听感。
All Notes, Selected Notes, All Events or Selected Events. The first Quantize drop down list allows you to quantize selected notes or events (not just notes) or the whole sequence (all notes or all events). This can come in handy if you just need to quantize a certain off section, or perhaps just a certain instrument, such as the hihats of a drum section. The second Quantize drop down list works in conjunction with whatever selection you make from the first. You can choose to have the quantizing of notes and/or events applied to the Position only, Position and Note End, Position and Note Length, Note End Only or Note Length Only.
“全部音符”、“选中的音符”、“全部事件”或“选中的事件”。第一个量化下拉列表,允许您量化选中的音符或事件(不仅仅是音符)或整个序列(全部音符或全部事件)。如果您只需要量化特定的结束部分,或者可能只需要量化特定的乐器,例如鼓部分的踩镲,这就很方便了。第二个量化下拉列表与您从第一个下拉列表中所做的任何选择相结合。您可以选择将音符或事件的量化,仅应用于“位置”、“位置和音符结尾”、“位置和音符时值”、“仅音符结尾”或“仅音符时值”。
The Strength setting adjusts how strictly notes are quantized. The lower you set the strength, the less 'magnetism' the grid has to the midi notes. This introduces subtle imprecisions to the quantizing which can make the outcome seem less clinical.
“强度设置”,调整音符量化的精确程度。设置的强度越低,网格对MIDI音符的“吸力”就越小。这给量化带来了微妙的不精确性,可能会使结果看起来不那么呆板。
The Grid and Length values determine which units (measured as fractions of a note) are used for quantizing. These can be selected from the drop down lists or entered manually in their respective boxes. They act in conjunction with the Allow notes to options (see below). Grid type can be straight, triplet, dotted or swing. If swing is selected, you will also need to specify swing strength.
“网格”和“时值”的值,确定用于量化的单位(以一个音符的分数作为测量)。这些选项可以从下拉列表中选择,也可以在各自的框中手动输入。它们与“允许音符”选项(见下文)配合使用。网格类型可以是“2等分”、“三连音”、“附点”或“摇摆”。如果选择了“摇摆”,您还需要指定“摇摆强度”。
Move left and Move right. If Quantize Position is enabled, these will ensure that notes are individually quantized to the start or end of the specified note fraction, whichever is nearest. Move left only will only quantize notes to the start, move right only will only quantize notes to the end.
“左移和”,“右移”。如果启用“量化位置”,这些将确保将音符单独量化到指定音符的分数的开始或结尾(以最近者为准)。仅“左移”将仅量化音符到开头,仅“右移”将仅量化音符到结尾。
Shrink and Grow. These are applied if Quantize Length is enabled. REAPER will extend or shorten notes by moving the end position of each note. You can enable either or both of these options.
“缩短”和“拉长”。如果启用了“量化长度”,则会应用这些设置。REAPER将通过移动每个音符的结束位置来延长或缩短音符。您可以启用这两个选项中的一个或两个。
The Only quantize range faders let you specify a percentage range for quantizing. 50% represents the midpoint between the grid lines. Values more than 50% are only really meaningful if “allow move right” or “allow move left” is disabled. The distance is measured from the grid line being quantized: normally it will select the closest line so that you will never be more than 50% away.
“仅量化范围滑块”,允许您指定量化的百分比范围。50%表示网格线之间的中点。只有在禁用了“允许右移”或“允许左移”的情况下,大于50%的值才真正有意义。因为距离是通过量化的网格线来测量的:通常它会选择最近的一条线,所以你永远不会超过50%的距离。
Fix Overlaps can be enabled to stop notes from overlapping as a result of being quantized.
可以启用“修复重叠”,以阻止量化后的音符重叠。
When the Use Grid Setting is selected, the Quantize Events dialog box will be as shown on the right.
选择“使用网格”设置时,量化事件对话框如右侧所示。
From the Grid drop-down list (at the bottom of the MIDI Editor window, next to the transport bar), select a note length value (such as 1/32, 1/16 or 1/8) and then select an item from the grid spacing type list. This can be straight, triplet, dotted or swing. If you choose Swing a strength fader is displayed (see above). This is used to adjust the swing setting within a range of -100% to 100%, or you can enter a value directly into the Swing % edit box to its immediate right. You should also set a Notes value: left at Grid, this will take its value from whatever is chosen for the grid. Otherwise you may select any other required value from the drop down list.
从网格下拉列表(位于MIDI编辑器窗口底部的走带栏旁边)中,选择一个音符的时值(如1/32、1/16或1/8),然后从网格间距类型列表中选择一项。这可以是“2等分”,“三连音”,“附点”或“摇摆”。如果你选择“摇摆”,会显示一个“强度滑块”(见上)。这用于在-100%到100%的范围内调整“摇摆”设置,或者您可以直接在其右侧的“摇摆”%编辑框中输入值。您还应该设置一个音符值:保持在网格,他将从为网格选择的任何内容中获取他的值。否则,您可以从下拉列表中选择其他需要的值。
Used well, swing can result in a more musically pleasing output. In essence, you define a percentage delay to be applied on the upbeat. For example, if you apply swing to 1/4 notes then those which coincide with the 1/2 note divisions will be unaffected by the swing, those that fall between these divisions will be delayed by the amount specified. Small amounts of swing (even 5% or less) can help to prevent a part from sounding too rigid.
如果使用得当,摇摆可以产生更悦耳的音乐效果。本质上,您定义了一个百分比延迟以应用在弱拍上。例如,如果将摇摆应用于1/4音符,则与1/2音符划分重合的音符将不受摇摆的影响,而落在这些音符之间的音符将按指定的量延迟。少量的摇摆(即使是5%或更少)可以帮助防止部分听起来过于僵硬。
Quantize is non-destructive - that is to say, the process can be reversed at any time.
量化是非破坏性的,也就是说,这个过程可以在任何时候逆转。
The various other commands on the Edit menu that are used with quantizing are:
与量化一起使用的编辑菜单上的其他各种命令包括:
Quantize notes using last settings
使用最后的量化设置量化音符
This bypasses the Quantize Events dialog box, making it easier for you to apply the same quantization settings to various disparate selections.
这将绕过量化事件对话框,使您可以更轻松地将相同的量化设置应用于各种不同的选择。
Quantize notes position to grid
量化音符位置到网格
This quantizes notes according to your grid settings.
这将根据您的网格设置量化音符。
Unquantize events
取消量化事件
Removes quantization and returns the notes to their previous state.
移除量化并将音符返回到其以前的状态。
Freeze quantization for events
冻结事件量化
Freezes the quantization for all currently selected events.
冻结所有当前选中事件的量化。
Shown above is an example. The top picture shows two unquantized notes selected. In the second picture they are quantized by moving them left. In the third picture, they are quantized by moving them to the right.
上面显示的是一个示例。上图显示选择了两个未量化的音符。在第二张图中,通过左移它们来量化它们。在第三张图中,通过右移它们来量化它们。
More quantize options are available in the MIDI Editor Action List, including actions to quantize note positions to specific divisions, ranging from 1/4 down to 1/64.
MIDI编辑器操作列表中提供了更多量化选项,包括将音符位置量化到特定划分的操作,从四分之一到六十四不等。
