Description

When changing the tempo during play, the time meter directly below the tempo display will not recalculate. Moving the play head will cause it to recalculate.

Reproduce

  1. Make a long track.
  2. Set tempo to a high value, i.e. 300.
  3. play the track and put the play head to the clock reads about 2 mins.
  4. Without pausing the song, drop the tempo to 10.
  5. The clock will stay at 2 mins
  6. Move the play head.
  7. The time recalculates to about 40 mins!
