Accelerando and Ritardando Support

[ma1kawa11]

In most music software such as notation editors or DAWs, there are support for dynamic changes in tempo over time, normally linearly (though some software allows different options for the curve). By taking a starting and ending BPM, it allows a user to create an Accelerando or Ritardando in the music without having to input multiple individual tempo markings in sequence.

There's a few potential ways this could be implemented. One is the method that was described above. However another, which would be potentially easier for compatibility with older versions, is just automating this step-wise motion in a way that is easier. In this case, it would look like a tool that would take a starting and ending BPM, and then instead of scaling between the two it would create 'steps' of different BPMs at a set amount of intervals instead. This method does have drawbacks though, specifically it would be harder to implement it in a way that allows for easy editing after use.

Either way, it would be nice to have some support, it would help greatly for timings in certain genres of music where live performing is common.
