Frequently Asked Questions
What is the formula to convert BPM into milliseconds?
The formula for one quarter note (1 beat in 4/4 time) is: Milliseconds = 60,000 / BPM. At 120 BPM, one quarter note equals exactly 60,000 / 120 = 500 milliseconds.
How do you calculate dotted and triplet notes from BPM?
A dotted note lasts 1.5 times longer than the straight note (Straight ms × 1.5). A triplet note lasts two-thirds of the straight note (Straight ms × 0.6667).
Why should I calculate reverb pre-delay in milliseconds?
Many vintage and analog-style reverb plugins only have a millisecond knob rather than tempo-sync switches. Calculating the exact millisecond equivalent of a 1/64th or 1/128th note ensures the vocal pocket stays rhythmically locked.
How do I convert milliseconds to Hertz for compressor and LFO modulation?
Frequency in Hertz is the reciprocal of period in seconds: Hz = 1000 / Milliseconds. At 120 BPM, a 500 ms quarter note oscillates at 1000 / 500 = 2.0 Hz.
