Tempo changes and resynchronization
Signaled changes in beat spacing require updating the internal rhythm instead of retaining the opening pace.
The player's decision
Keep the old pulse or use the transition cue to prepare for denser beats?
Original scenario
Original setup: four slow bars lead into a faster section with two warning cues. Compare with hidden cues to locate surprise-driven failures.
Start with this prototype
Build sixteen beats, one signaled tempo change and one input. Log early/late milliseconds, show a beat track and provide calibration and slow practice. Meet an accuracy target; omit a full chart editor.
Change one variable
Tune cue lead time before tempo difference to avoid increasing both learning demands together.
What to observe in a playtest
Are beats neither duplicated nor dropped at the change? Does resume provide a count-in?

Original analysis · version 1
Common pitfall
Restarting beat accumulation at the switch can lose phase; use a continuous beat schedule.
Observations and sources
Cases refer to public documentation. Developers and community wikis are credited separately; document review is not a claim of hands-on testing.
- Hi-Fi RUSH
BPM RUSH raises tempo between waves, explicitly using speed progression as a challenge.
- Rhythm Doctor
Complex rhythms and irregular meters require relearning the pulse, a structural comparison rather than simple acceleration.
