I recorded some MIDI using Cubase 5. The tempo of the recording doesn't match that of the underlying grid Cubase displays. How can I change the tempo (spacing) of the grid without affecting the duration of the notes? I would like to do this globally, not locally (time warp tool).
Change your track settings from tempo based to time based. Then change the tempo of your project to fall with your recording. It is the little icon with the clock (when your track is time based) or a note (when it is tempo based). Then you can revert your track back to being tempo based.
There are two ways to get an audio part and tempo track to line up. Since you're looking to change the tempo to match the audio, the first method is what you're looking for.
Method 1: Change tempo to match the audio track
- First, select the audio part you want to get the tempo changes from.
- Then, look for an item in the audio processing menu in the main project view that brings up a dialog where you can either tell Cubase to "detect beats" or manually tell it how many measures elapsed over a certain amount of time. This dialog allows you to have Cubase automatically add tempo changes to match your audio track's tempo fluctuations with great precision.
Method 2: Warp the audio so it stays with the project's tempo track
In the event that you would like to instead warp the audio to match a steady tempo, then the second method, using hitpoints to create audio warp markers, will appeal to you. To do this:
- Double-click the audio part that has undesirable fluctuations in tempo. This will open that audio part in an audio part edit window.
- Detect hitpoints
- Generate warp markers from hitpoints
- Warp the audio to match the grid
- If these auto alignment results need tweaking, then you can add your own additional hitpoints/warp markers afterwards and click-and-drag warp them yourself to match the grid.
I have personally used these methods in Cubase 7 and Cubase 7.5.
