BPM parameters

  • Beats-per-minute: 128 BPM
  • Beats-per-second: 2.1333 Hz
  • Length of 1 beat: 0.4688 second = 469 msec
  • Length of 1 bar (4 beats): 1.875 second

    • Loop & song length

    These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
    1 beat =469ms =2.13Hz
    2 beats =938ms =1.06Hz
    3 beats =1.41sec =0.71Hz
    4 beats =1.88sec =0.53Hz
    6 beats =2.81sec =0.36Hz
    7 beats =3.28sec =0.3Hz
    8 beats =3.75sec =0.27Hz
    10 beats =4.69sec =0.21Hz
    12 beats =5.63sec =0.18Hz
    16 beats =7.5sec =0.13Hz
    24 beats =11.25sec =0.09Hz
    32 beats =15sec =0.07Hz
    These are the lengths of multiple bars/measures (handy for estimating the length of a song).
    2 bars =3.8 sec
    4 bars =7.5 sec
    8 bars =15 sec
    16 bars =30 sec
    24 bars =45 sec
    32 bars =60 sec
    40 bars =75 sec
    48 bars =90 sec
    60 bars =112.5 sec
    80 bars =150 sec
    100 bars =187.5 sec
    120 bars =225 sec

    Fractions → millisecs

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