DJ and Music Production Tools
DJing and music production rely heavily on precise timing relationships. BPM sync ensures that two tracks play at the same tempo, while harmonic mixing (using the Camelot wheel or musical key) ensures smooth key-compatible transitions between songs.
Delay times, LFO rates and loop lengths must all be synced to the tempo for them to feel musical. A quarter note at 120 BPM is exactly 500 ms. Our calculators provide delay times for all note values including dotted and triplet variations, saving producers from manual calculation.
Understanding the relationship between BPM, samples and milliseconds is fundamental to music production workflow, particularly when working with hardware samplers, drum machines and synthesisers that require precise timing values.
