BPM: Fast dub/reggae

Give tempo and time signature

BPM parameters

  • Beats-per-minute: 90 BPM
  • Beats-per-second: 1.5 Hz
  • Length of 1 beat: 0.6667 second = 667 msec
  • Length of 1 bar (4 beats): 2.6667 second

    • Loop & song length

    These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
    1 beat =667ms =1.49Hz
    2 beats =1.33sec =0.75Hz
    3 beats =2sec =0.5Hz
    4 beats =2.67sec =0.37Hz
    6 beats =4sec =0.25Hz
    7 beats =4.67sec =0.21Hz
    8 beats =5.33sec =0.19Hz
    10 beats =6.67sec =0.15Hz
    12 beats =8sec =0.13Hz
    16 beats =10.67sec =0.09Hz
    24 beats =16sec =0.06Hz
    32 beats =21.33sec =0.05Hz
    These are the lengths of multiple bars/measures (handy for estimating the length of a song).
    2 bars =5.3 sec
    4 bars =10.7 sec
    8 bars =21.3 sec
    16 bars =42.7 sec
    24 bars =64 sec
    32 bars =85.3 sec
    40 bars =106.7 sec
    48 bars =128 sec
    60 bars =160 sec
    80 bars =213.3 sec
    100 bars =266.7 sec
    120 bars =320 sec

    Fractions → millisecs

    These are some common fractions (handy for setting delays and modulation parameters)
