The tempo and time signature editor window lists all of the tempo and time signature changes in the composition. You can edit an individual tempo or time signature change by double-clicking on it.

: I can't remember clearly but have the tempo and time signature dialogs been separated in thorn? If so I need to revamp both of the pages for these. Advise please. SOM

To change the time signature, use Composition → Add Time Signature Change… or double-click on the existing time signature in the transport window or tempo and time signature editor.

Rosegarden provides two ways to set tempo from a segment that you have recorded or imported:

Audio Segment Duration

Use Composition → Set Tempo to Audio Segment Duration when you have imported or recorded an audio segment that you know is exactly one bar long, and you want to ensure that the tempo for surrounding note events is set appropriately.

This function uses the duration of the selected segment (which must be an audio segment of a single bar) to work out a single matching tempo setting. It does not analyse the content of the audio segment in any way – it simply looks at how long it is.

Beat Segment

Composition → Set Tempos from Beat Segment analyses a segment of MIDI events that are assumed to be at beat positions for the current time signature, and sets a series of tempo changes according to the time elapsed between consecutive beats.

You can use this to set an overall tempo map for a composition by “tapping” tempo in a recorded segment. For example, you can record from a MIDI keyboard and tap a series of single notes at approximate beat positions, speeding up and slowing down gradually; then select the recorded segment and use this function to set a tempo map that speeds up and slows down to match your tapping. : I added Audio Segment duration and Beat Segment to this part as it seemed so lonely in the main doc. However it doesn't really seem to be part of this page either esp as this is a page that is linked to the Time Signature dialog. Perhaps it needs its own page and we link to it from here. Actually the two sections Tempo and Timesignatures need rethinking the structure. SOM
