Tempo ruler modes

- -

- The Tempo ruler has two modes: editing tempo and mapping tempo. The mode can - be selected in the Edit > Tempo menu. - Additionally, users can select which one should be enabled by default - Edit > Preferences > Metronome > Default tempo - ruler state for new sessions. -

- -

- 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. -

Tweaking positions of markers

- To tweak the position of a tempo marker, hover the bar line where it's - located, then click and drag it left or right. -

Ramping between tempo markers

- -

- In some cases, tempo fluctuates gradually during the performance. To deal - with that, it's possible to set a tempo ramp. Create two markers, one where - tempo begins changing, and one where it starts changing. Then hover the - mouse pointer between bar lines and start dragging to the left or to the - right. Dragging to the left increases the tempo at the beginning and lowers - it towards the end. Dragging to the right increases the tempo towards the - end and lowers it towards the beginning. -
