Some plug-ins and pedals show milliseconds or hertz but no tempo-sync menu. A conversion table supplies a repeatable starting value. It cannot decide which rhythm, feedback, decay, or modulation depth fits a mix.
Enter a note-aligned delay
Choose the rhythmic repeat first, then copy its milliseconds. A dotted eighth and an eighth-note triplet are different fractions even when both feel syncopated.
Treat reverb time as a starting point
A note duration can align pre-delay or another time parameter to the grid, but room character and decay perception depend on the signal and processor. TempoCalc supplies time, not a mix verdict.
Use hertz for cycle-based controls
When a modulation control accepts hertz, use 1000 divided by the selected milliseconds. Confirm whether the device defines one full cycle in the same way and whether it applies tempo smoothing.
Check the destination control
Hardware may round values, cap its range, quantize internally, or label divisions differently. Tempo automation and swing also move events away from one constant value. Verify the result in the actual project.
