    BPM to millisecond conversion chart?

    Sign in to disable this ad
    I have an Eventide H3000, and not all the delays, reverb tails, sweeps etc.. are syncable to MIDI clock. (Why some and not others Eventide?)

    Anyway, I was wondering if there is some sort of key/cheat sheet that shows BPM divisions in milliseconds for all of the different note divisions (quarter, eighth, dotted eighth etc...) Does anybody know of one? Thanks.

    sensorium (sen·so·ri·um) The term sensorium (plural: sensoria) refers to the sum of an organism's perception, the "seat of sensation" where it experiences and interprets the environments within which it lives.

    It's 60 / BPM * 1000.

    [Edit: and of course an optional multplier for the desired note value ... Using this for a while, the values just stick to your head.]

    digital delay
    60 000 milliseconds/min divided by tempo (bpm) = ? milli/beat

    here's one spot, of many, that you can use http://www.jlstudios.ca/delay_time_calculator.html

    here's another that you can download http://www.dontcrack.com/freeware/do...ay-Calculator/

    Or I might as well just...

    for bpm in range(75,175):
    print "BPM:", bpm
    print "Whole:", round(60.0 / bpm * 4000,1),
    "Half:", round(60.0 / bpm * 2000,1)
    print "Quarter:", round(60.0 / bpm * 1000,1) ,
    "Eighth:", round(60.0 / bpm * 500,1)
    print "Sixteenth:", round(60.0 / bpm * 250,1)
    print "---------"
