Musicians struggle to develop rhythmic precision when practicing complex tuplets with tempo changes

Musicians, particularly intermediate to advanced players, find it extremely difficult to practice tuplets (complex rhythmic subdivisions like triplets, quintuplets, etc.) while the tempo is changing. Current metronome apps and practice tools don't adequately simulate real-world performance scenarios where conductors or ensemble tempos fluctuate, leaving musicians unprepared for live performance and unable to internalize the muscle memory needed for reliable execution.
