9.1 Creating Loops
9.1 创建循环

Any audio, MIDI or click source Item can be looped. Indeed, by default REAPER media items are loop enabled. You can disable this for individual items in the Media Item Properties dialog box, or globally (for MIDI and imported items) on the Project, Media Item Defaults page of your Preferences.
任何音频、MIDI或击拍源对象都可以循环。实际上,默认情况下,REAPER媒体对象是启用了循环的。您可以在媒体对象属性对话框中,对单个对象禁用此功能,也可以在“首选项”的“工程”、“媒体对象默认设置”页面上,对单个对象禁用此功能(对于MIDI和导入的对象)。
The loop point is defined by the duration of the source media. If you insert an item that is four bars long, it will loop every 4 bars, if it is 8 bars, it will loop every 8 bars, etc.
循环点由源媒体的持续时间定义。如果您插入一个4小节长的对象,它将每4小节循环一次,如果它是8小节,它将每8小节循环一次,以此类推。
Note that in the following examples, if you are using beats for your timebase, the item must be an exact number of beats in length, or it will not loop in sync. If necessary, adjust the playback rate (Media Properties) while preserving pitch, then glue the item to do this.
请注意,在下面的示例中,如果您使用节拍作为时基,则该对象的长度必须是准确的节拍数,否则它将不会同步循环。如有必要,在保持音高不变的情况下,调整播放速率(媒体属性),然后粘合对象以执行此操作。
To Loop an entire Item:
要循环整个对象,请执行以下操作:
1. Hover the mouse over the edge of an Item until the Cursor changes to a double-headed arrow (see right).
1.将鼠标悬停在对象边缘,直到光标变为双箭头(见右)。
2. Drag the Cursor to extend the Item. Each loop point will be indicated by a notch in the item edges.
2.拖动光标以扩展对象。每个循环点将由对象边缘上的凹槽指示。
3. The length, start time and end time of the looped item will be displayed as you drag the edge of the loop.
3.当您拖动循环的边缘时,将显示循环对象的长度、开始时间和结束时间。
Cropping and Looping:
裁减和循环:
If you wish to loop only part of an item, then one method is to first crop and glue the item.
如果您希望只循环对象的一部分,则一种方法是,首先裁减并粘合对象。
1. Make sure snapping is enabled. Hover the mouse over the edge of the Item until the Cursor changes to a doubleheaded arrow. Click and drag the mouse in on the item to make it shorter, so that you are left with only that part of the item that you want to use as the basis of the loop. Release the mouse button.
1.确保开启吸附功能。将鼠标悬停在对象边缘,直到光标变为双箭头。在对象上单击并拖动鼠标,使其变短,这样就只剩下对象中要用作循环基础的那部分了。松开鼠标按钮。
2. Right click over the item and choose Glue items.
2.用鼠标右键单击对象,然后选择“粘合对象”。
3. Now drag the Cursor to extend the Item. Each loop point will again be indicated by a notch in the edges of the item. Extend the loop as required.
3.现在拖动光标以扩展对象。每个循环点将再次由对象边缘的凹槽指示。根据需要扩展循环。
Changing Playback Rate:
改变播放速率:
There may be times when you will wish to change an item's playback rate, for example to keep it in sync. Taking the same example as above, you would first display the Item Properties box, and most probably make sure that Preserve pitch when changing rate was selected. You could then change the Playback rate (for example, to 2.0). This would have the effect shown here. The original item (looped) as shown above has had its playback rate modified (right).
有时您可能希望改变对象的播放速率,例如使其保持同步。以上面相同的示例为例,您将首先显示对象属性框,并且很可能会确保选中了“改变播放速率时保持音高”。然后可以改变播放速率(例如,改变为2.0)。这将产生如下所示的效果。如上所示的原始对象(循环)已修改其播放速率(右)。
Creating a Loop from a Time Selection
从时间选区创建循环
Another way of creating a loop from only part of an item is to select the required item, highlight the required part of it as a time selection, right click, choose Copy loop of selected area of items, remove the original, then paste in the loop in its place. This is shown here:
另一种仅从对象的一部分创建循环的方法是选择所需对象,将其所需部分高亮显示作为时间选区,右键单击,选择“复制对象中选中的区域为循环”,删除原始对象,然后粘贴到循环中的相应位置。如下所示:
1. Select first the source item, then select the area to be looped (see above). Either press Ctrl Alt L or right click and choose Copy loop of selected area of item.
1.首先选择源对象,然后选择要循环的区域(见上文)。按Ctrl+Alt+L-或右键单击并选择“复制对象中选中的区域为循环”。
2. Select the track and position to which you want the item copied.
2.选择要将对象复制到的轨道和位置。
　　3. Press Ctrl V to paste in the area to be looped.
3.按Ctrl+V键粘贴到要循环的区域中。
4. Drag the cursor from the edge of the item as before to create the loop.
4.如前所述,从对象边缘拖动光标以创建循环。
