Real-Time Properties on Tracks and Clips
For more information, see the following topics:
Real-Time Properties can be configured to apply to an entire track (all clips on that track), or on a clip-by-clip basis. Track-level properties also provide real-time MIDI input processing of velocity and transposition.
The presence of track-based Real-Time Properties are indicated by a “T” displayed in the upper right-hand corner of MIDI clips. Clip-based Real-Time Properties are indicated by an “R” displayed in the upper right-hand corner of the clip. Clips boundaries including the “T” and the “R” displays are indicated in Notes view and in MIDI Editor windows, but not in the Score Editor window.
Clip-Based Real-Time Properties
Clip-based Real-Time Properties can only be applied using the Real-Time Properties window (Event > MIDI Real-Time Properties). Real-Time Properties can be applied to multiple clips. Once Real-Time Properties have been assigned to a clip, the clip can be moved or copied and pasted and retain its Real-Time Properties.
Track-Based Real-Time Properties
All track-based Real-Time Properties consistently apply to MIDI data throughout the entire track. However, clips with clip-based Real-Time Properties will take precedence over any track-based Real-Time Properties. You can clear clip-based Real-Time Properties by selecting the clip and clicking the Clear Clip Properties button in the Real-Time Properties window (see Writing Real-Time Properties to Tracks or Clips).
For greater flexibility, when Real-Time Properties are assigned on a track basis they are actually contained in a track playlist. This lets you create multiple playlists containing different Real-Time Property settings.
