What: Time-stretch
Where: can be found on Audio Events
Why: Any sort of real time time stretching happens on this event. This can be audio warping, VariAudio (only time changes, not pitch changes) or simply a time stretch (or compression) of the event itself.

What: Musical Mode (includes time stretch)
Where: can be found on Audio Events
Why: Event is set to “Musical Mode”; that means the speed of the audio event will follow the tempo setting of the project; since this is achieved by means of time stretching the time stretch icon is also displayed

What: Do not follow Global Transpose
Where: can be found on MIDI Parts and Audio Events
Why: You can define a project root key. This allows for quick transposing of the project. A part with this icon will not follow the project transpose (aka Global Transpose).

What: Shared
Where: can be found on MIDI Parts and Audio Parts
Why: any edit to a shared part will also take place on all the other parts that “are shared” with this one
