How accurate are the millisecond calculations?

All calculations are rounded to exactly two decimal places to ensure precision for digital audio workstations and sequencers.

Can I calculate dotted or triplet notes?

Yes, by using the `calculate_note_duration` tool, you can specify if a note is dotted or part of a triplet subdivision.

What happens if I provide an invalid BPM?

The tools will return a success status of false and provide an error message describing why the calculation failed (e.g., non-positive BPM).

This MCP server provides high-precision timing calculations for musicians, producers, and developers. It allows AI agents to convert beats per minute (BPM) into exact millisecond durations for standard note values like whole, half, quarter, eighth, sixteenth, and thirty-second notes. The tool also accounts for rhythmic modifiers such as dotted notes and triplets. Use calculate_beat_duration to find the base beat length, calculate_note_duration for specific subdivisions, or generate_rhythm_summary to get a complete table of all note values at a given tempo.
