About tracks, sequences, markers, bars, metrics and tempo

Each scoob track consists of four sequences:

1. the events sequence of scoobs (score objects). This one is iterated over by default.

   access

   any access method is by default to the event sequence. To get that, use: ($mytrack events)

   iteration

   [ftm.iter] or [ftm.iter @mode events]

2. the tempo sequence contains float values with the current tempo in bpm.

   access

   ($mytrack tempo)

   iteration

   [ftm.iter @mode tempo]

3. the metric sequence contains metric events for bars and metric signature changes

   access

   ($mytrack metric)

   iteration

   [ftm.iter @mode metric]

   properties 

   num 

   bar number

   meter 

   metric signature as string, e.g. 4/4

4. the marker sequence contains marker events that can bear any property, but above all cue, label (N.B.: there is also a separate cue property of the scoob score object)

   access

   ($mytrack markers)

   iteration

   [ftm.iter @mode markers]

   properties 

   cue 

   cue number

   label 

   text

   <any> 

   <any type>
