18.38 速度/拍号和播放速度包络

In Chapter 10, you learnt how to change time signature and/or tempo within a project. Another (and perhaps more intuitive) way of doing this is to use the Tempo/Time Signature Envelope. To display this envelope in the main REAPER arrange window:
在第10章中,您学习了如何在工程中更改拍号或速度。另一种(也许更直观的)方法是使用速度/拍号包络。要在主REAPER排列窗口中显示此包络,请执行以下操作:
1. From REAPER's main menu choose View, Tempo envelope. This displays the Master and its tempo envelope in arrange view.
1.从REAPER的主菜单中选择“”视图、“速度包络”。这会使主控及其速度包络显示在排列视图中。
2. Set the Automation mode for the Master Track to Read.
2.将主控轨的自动化模式设置为读取。
Wit the tempo map visible an envelope appears on the Master Track in arrange view. The default envelope range (bpm) is set in your Preferences, on the Editing Behavior, Envelope Display page (Chapter 22). You can vary this range for individual projects: right click over the envelope and from the menu choose Envelope defaults, Tempo envelope range to open a dialog where you can do this.
当速度映射可见时,在排列视图中的主控轨上会出现一个包络。默认的包络范围(Bpm)是在您的首选项中设置的,在“编辑行为”的“包络显示”页面上(第22章)。您可以为各个工程更改此范围: 在包络上单击鼠标右键,并从菜单中选择“包络默认设置”、“速度包络范围”,以打开一个对话框,您可以在其中执行此操作。
To select your preferred point shape, right click on the envelope and from the context menu choose Envelope defaults, Default point shapes, then either Linear or Square.
要选择首选的点形状,请右键单击包络,然后从上下文菜单中选择“包络默认设置”--“默认点的形状”,然后选择“线性”或“正方形”。
This envelope can be modified like any other. You can add points (Shift click, or to draw freehand use Ctrl drag), move them, delete them, adjust them, etc. However, the master tempo envelope cannot be modified by freehand drawing. Moreover, editing multiple points at once on this envelope causes each point to be adjusted pro rata, not by a constant BPM value.
可以像修改任何其他包络一样修改此包络——您可以添加点(按住Shift键单击,或者按住Ctrl拖拽手绘)、移动点、删除点、调整点等。但是,不能通过手绘修改主控速度包络。此外,同时编辑此包络上的多个点会导致按比例调整每个点,而不是按恒定的BPM值进行调整。
With each envelope point a tempo/time signature marker is also inserted on the timeline - editing their values has the same effect as editing the envelope points. If you move them, the points move with them (and vice versa).
对于每个包络点,还会在时间轴上插入速度/拍号标记————编辑它们的值与编辑包络点具有相同的效果。如果移动它们,点也会随之移动(反之亦然)。
REAPER's Actions List also includes an action Adjust entire envelope tempo... This opens a dialog box which offers you the options of adjusting the entire envelope by a percentage or by a set number of beats per minute.
REAPER的操作列表还包括一个“调整整个包络速度...”的操作,这将打开一个对话框,其中提供了“按百分比”或“按设定的每分钟节拍数”调整整个包络的选项。
You can also add to the Master a Playrate envelope which can be used to automatically speed up or slow down project playback. This envelope is applied to all tracks, audio and MIDI. To do this:
您还可以将播放速率包络添加到主控面板中,该包络可用于自动加快或减慢工程的播放速度。此包络适用于所有轨道、音频和MIDI。要做到这一点:
1. Click the Envelopes button in the Track Master to display the Master Envelopes window. Now tick the item Playrate. Make sure this item is marked as both Visible and Armed.
1.单击轨道主控中的包络按钮。这将显示主控的包络窗口。现在勾选“对象播放速率”。确保此对象标记为可见和预备。
2. Close this window.
2.关闭此窗口。
