Musical metrics

Musical metrics are hierarchic

  • The tempo, and musical position in an interval is either relative to this interval (if the 4/4 button in the inspector is pressed) or it’s taking the musical information from its closest parent (recursively).

This means that polyrhythmic scores are possible.

To change the musical signatures, go into the children intervals, in full view.

Tempo

Likewise, by default the tempo is the global one. Intervals support tempo curves, which can give them a different speed behaviour. The interval’s children will all take this tempo unless another more precise tempo is given at a deeper nesting level.

Usage

  • Processes which are able to use tempo & metrics information (audio plug-ins, LFO, arpeggiator, etc) will do so automatically
  • Triggers can be quantified to fall on the next quantification date from when they are triggered.
