Tempo Map Panel
  1. Choose Tools in the menu bar.
  2. Choose Tempo Map... from the Tools menu.

OR

Click on the Tempo button located near the top-right corner of the score:

There are 3 pages of possible tempo changes available in this panel, so a total of 120 tempo changes can be indicated for each score.

To use the Tempo Map, fill in the tempo changes by indicating the measure number, the beat, and the metronome value, and note value of the tempo (the note is a pull down menu.) You can also choose a transition method between the previous tempo and the next one. The possible transition methods are:

  1. Immediate tempo change at the time indicated.
  2. Linear change of tempo between the previous tempo and the new tempo.
  3. Exponential change of tempo (remaining closer to the previous tempo and moving more quickly to the new tempo toward the end of the time period.)
  4. Reverse Exponential (Logarithmic) change of tempo (moving more quickly toward the new tempo at first and more slowly toward the end of the time period.)
  5. Sigmoid change of tempo (moving slowly away from the original tempo, then more quickly during the middle of the change and more slowly again as the new tempo is approached.)
Check the Use Tempo Map button to have NoteAbility use these values during playback.

In situations where you want a tempo to be steady for a period of time followed by an accel... or a dim... you will have to indicate the starting point of the tempo change by repeating the same tempo at the place where the tempo change will start. In the example above, a tempo of eighth note = 100 is reached at measure 7 beat 4, and is steady until measure 9 beat 1. At this point there is an ritardando to 80 at measure 9 beat 3.

Although measure number and metronome values should be integers, the beat position can be a real numbers such as 1.25 or 3.376. The tempo slider and tempo field in the Control panel are updated as new tempi occur during playback.

The sort button is used to sort the tempo indications so that they are sequential. If you decide to add a new tempo change in the middle of your score, you can add it at the bottom of the tempo map and click on the sort button to have it inserted at its correct location.

- The Tempo Map is used when the score is played from the beginning or when played from the Entry Cursor (using the playback controls on the Control panel.) When a selected group of notes is played (using the Play Sel. menu item) the tempo indicated in the Tempo field of the Control panel is used.

- The Tempo Map is saved with your score.
