Some guitarists prefer to dial in the timing on their delay pedal; some musicians also play with the metronome. Daniel has compiled a comprehensive list of tempos for your metronomes and delay pedals - in beats per minute (BPM), milliseconds between beats (MS), and milliseconds for the dotted 8th note delay. Example below, and download the file here.
BPM (beats per minute) is the unit in which we measure a song's tempo, like time is measured in minutes, hours, months & years. Song's tempos are measured in BPMs. The BPM is how many beats per minute the song has. A song with a BPM of 60 would have a beat every second.
MS (millisecond) is a measure of time as well, like a minute or hour. A millisecond is one thousandth of a second. So 1000 milliseconds equals a minute. MS are what most delay pedals use as a way to dial in your delay time, some pedals you can't *dial* in exactly like the DD-5 but you can tap the tempo in. Wheres some like the DD-20 you can use both your BPM or the MS to dial in exactly the time, and yes the DD-20 happens to also have tap tempo
To figure out the BPM of a song I use a program called 'Tap Tempo' which you can download for free: http://www.analogx.com/contents/download/audio/taptempo.htm. All you have to do is play the song you are working on and every quarter note press the space bar. Press it about 25 times to get a accurate time. I have had this for a few years and it is a very helpful tool to use. It will give you a accurate BPM of the song.
Now that you have established the BPM of you song lets find the correct time for your delay.
I found this program a while back and it is another useful tool to use, It's called 'Delay Time Calculator', here is the link http://www.brothersoft.com/delay-time-calculator-89931.html. Just type the BPM of the song into the field where it says tempo pick a note value click 'calculate' and it will automatically tell you the millisecond! You also have the choice of dotted or triplet notes.
