The Delay Time Calculator by Behringer is a very useful tool for
matching delay times from digital reverbs and digital delay processors
to the correct music tempo you are playing or recording. If the
delay times do not match the tempo, most likely the music will not
sound very good because it will be out of sync. An optimum situation
would be to match your delay times as closely as possible to the
beat. If you are using long delays or creating music with loops,
a Delay Time Calculator becomes an absolute necessity.
Using this Delay Time Calculator you may calculate your delay times
in milliseconds for the digital reverb or digital delay processor
you are working with. You must first enter the BPM (beats per minute)
into the calculator. To do this, move the shuttle wheel until it
displays the correct BPM of the music. If you are using a sequencer,
then enter the corresponding number from the BPM display. If your
music is played and not sequenced, count the quarter notes for a
one minute duration to estimate the BPM manually. One beat is equal
to a quarter note in most cases.
The calculator will now display the millisecond values for a full
note, half note, quarter note, eighth note, 3/16 note, sixteenth
note, and a sixteenth note triplet. The most common delay times
are quarter note or eighth note delay. You can achieve some creative
results by taking your original BPM and dividing or multiplying
by two or four, enter that number into the Delay Time Calculator
and use the corresponding millisecond note values.
