The importance of low and consistent latency in interactive music systems is well-established. So how do commonly used tools for creating digital musical instruments and other tangible interfaces perform in terms of latency from user action to sound output?
We present a dataset of annotations of tracks containing metric modulations.
A metric modulation is defined by a relatively abrupt change of metrical structure over time.
In order to capture this, for each track the annotations consist of:
- Beat locations
- Downbeat locations
- Metric modulation locations (i.e. timestamps of the metrical structure change)
- All metrical level pulse rates
