However, I mentioned at the start of this column that the Project Browser allows access to every Track in a Cubase Project, meaning that you can also use the Project Browser as a replacement for the Master Track List Editor, entering tempo and time signature changes numerically rather than graphically.
Tempo and time signature changes are actually handled by different Tracks, as displayed in the Project Browser, even though the Tempo Track editor displays both these types of changes. The Tempo Track unsurprisingly handles tempo changes, while time signature changes are actually dealt with by the Signature Track, and the reason for this is actually quite logical. Since the events in the Tempo Track are only active when the Master button is enabled on the Transport Panel, time signature changes need to be kept separate as it would become quite confusing if these changes could also be toggled.
To enter a time signature change numerically, simply select the Tempo Track in the Project Browser, set the Project Cursor to the position you want the tempo change to occur, click the Add button on the Project Browser's toolbar and edit the tempo to the required value. Unfortunately, while the Project Browser will display Ramp tempo events (those that create either a rallentando or accelerando from the previous tempo to the new tempo), only Jump tempo events (those that instantly change to the new tempo) can be created in the Project Browser. This also means that you can't change the type of tempo event in the Project Browser, so you have to revert to the Tempo Track editor if you want to alter the type of a tempo event or insert a Ramp tempo event.
Time signature changes are more straightforward: to enter a time signature change, select the Signature Track in the Project Browser, set the Project Cursor to where you want the change to take place (I might be stating the obvious, but time signature changes can only occur at whole bar positions), and edit the new time signature to suit.
