The Tempo ruler allows changing tempo within one session, either abruptly or
gradually over time. This is done by placing tempo markers on the ruler and
- setting up how exactly the transition happens.

On the screenshot below, there are 4 bars of music at 120bpm starting at bar 27,
then the tempo changes abruptly to 140bpm and goes on for another 4 bars at that
tempo, then abruptly changes back to 120bpm and within the next 4 bars gradually
- goes back to 140bpm, then continues at 140bpm until the end of the session.

- The Tempo ruler has two modes: editing tempo and mapping tempo. The mode can
- be selected in the Edit > Tempo menu.

- The Map Tempo mode is best suited for cases when there is a live recording
- of an instrument or multiple instruments, with some tempo imperfections. So
- before more instruments are added, e.g. MIDI-programmed drums, the tempo map
- needs to be adjusted to match the actual performance. In this mode, MIDI data
- is not adjusted for tempo map changes, so if the live recording contains
- both audio and MIDI tracks, the notes will stay exactly where they are.
- Additionally, tweaking tempo markers does not change the wall clock position
- of other tempo markers.
-
- The Change Tempo mode is better suited for cases when the musician either
- starts a session from scratch and creates the tempo map at the beginning, or
- when they do need the MIDI data to be adjusted for tempo map changes.
- Tweaking tempo in a tempo marker in this mode also changes the wall clock
- position of subsequent tempo markers.

- When working with the tempo ruler in the Change Tempo mode, each tempo
- marker exposes several editable properties:

- In the Map Tempo mode, tempo markers also have these properties, but except
- for the BPM at the start value, they are not exposed in the user interface.
