Hi,

if you also should dislike to use a calculator each time you want to
sync beats per minute to milliseconds, the following script might be
useful for you, too.

Run

  bpm2ms <beats_per_minute>

just running

  bpm2ms

without a value defaults to 120 beats per minute.

I wrote it some minutes ago, I'm not only tired of using the
calculator, but was really sleepy, too. Maybe I made one or the other
typo.

With root privileges store the script as /usr/local/bin/bpm2ms and then
run

sudo chmod a+x /usr/local/bin/bpm2ms
sudo apt update
sudo apt install apcalc

[weremouse@moonstudio ~]$ bpm2ms --help
Usage:
  bpm2ms <BPM>
Version 2017-Feb-03 Rocketmouse
[weremouse@moonstudio ~]$ bpm2ms 60 | head -1
(60000ms/60BPM)*4*(1/1)= 4000ms
[weremouse@moonstudio ~]$ bpm2ms | head -9
(60000ms/120BPM)*4*(1/1)= 2000ms
(60000ms/120BPM)*4*(3/4)= 1500ms
(60000ms/120BPM)*4*(1/2)= 1000ms
(60000ms/120BPM)*4*(1/4)= 500ms
(60000ms/120BPM)*4*(1/8)= 250ms
(60000ms/120BPM)*4*(1/12)= ~166.66666666666666666667ms
(60000ms/120BPM)*4*(1/16)= 125ms
(60000ms/120BPM)*4*(1/24)= ~83.33333333333333333333ms
(60000ms/120BPM)*4*(1/32)= 62.5ms
[weremouse@moonstudio ~]$ ls -l /usr/local/bin/bpm2ms 
-rwxr-xr-x 1 root root 508 Feb  3 05:15 /usr/local/bin/bpm2ms
