[in menu Modify/Tempo operations]

This operation sets a series of tempo changes (increasing or decreasing) for a certain time range. This is used to increase or decrease tempo linear between two song positions.

Start time position

start time (in seconds) from beginning of the song (e.g. 10.7)

End time position

end time (in seconds) from beginning of song (e.g. 30.0)

Tempo at start position

current song tempo at start position (a hint)

Tempo at end position

current song tempo at end position (a hint)

New start tempo

tempo at start position in beats per minute (e.g. 98.0)

New end tempo

tempo at end position in beats per minute (e.g. 106.0)

Step units

distance between two tempo changes in MIDI units

Hint: Start time position must be lower than end time position.

Hint: Start tempo and end tempo must be in range 30.0-255.0 bpm.

Hint: If start tempo is smaller than end tempo then tempo will slowly increase

Hint: If end tempo is smaller than start tempo then tempo will slowly decrease.

Hint: If start tempo is same as end tempo then only one tempo change will be added and existing tempo changes in given range will be removed.

Number of generated tempo changes

After all required fields are entered the message below the edit fields appears which tells how many tempo changes would be generated using current settings.

Hint: Be sure that the number of tempo changes is not too high, because this could produce big MIDI file size and could be a problem for some MIDI players. If the number is too high then choose higher step units value till the number is acceptable.
