Using over 32 years experience with 2 models of BEAT BUG (the first
product of its kind), every effort has been made to strike a balance between;
including as many features as possible, power conservation, simplicity and
logical/user-friendly operation. But certainly there will be a short learning
period for you. Just fool around with the REF for a while and give yourself time
to get to know it. It helps a lot to have the REF in-hand performing each
operation as you read this.
REF is sleeping!
advance the threshold knob clockwise. A raised white line on this knob is now viewed at its
lowest position. Picture this line as a bar you need to jump over.
A higher bar is harder to clear, requiring louder taps! Now
wake your REF with a fingernail tap. A
" 1" is displayed for 30
seconds and the REF will go back to sleep if no further action is taken. This
short initial wake period conserves battery power if accidentally
The REF is now ready to monitor taps heard by its internal and external
sensors and provide an instantaneous beat-to-beat evaluation in real-time;
displaying beats per minute it technically is a “TEMPOMETER”. This is the
REF’s default mode and no matter what the present mode, unless you’re
pressing a button, a tap will always take you to this mode. Raising the
threshold (CCW) will filter out ghost notes and the decimals will
flash when an accented beat has been heard. Maintaining a consistent
reading is the name of the game. Range in this mode is 10 to 255 bpm.
Hold the REF in one hand and tap a fingernail on its back surface; or
place the REF on a music stand or hard tabletop and tap on your REF next to the
numbers. Your taps will be reflected off the hard surface and hit the REF's
Half the song tempo will be displayed if a 2,4
“backbeat” is tapped. Quarter notes will display actual song tempo and
subdivisions of quarters will display multiples of song tempo. Irregular
patterns can also be monitored, as long as it's a repeating pattern and there's
a rest in the pattern long enough for a number to be read. It doesn't matter
what or where a number is, nor the time signature. As long as you consistently
see the same (or nearly the same) number in the same place your meter is steady.
(Please don’t try to do the math every time. We will not be responsible for
you driving yourself and fellow band members nuts.) Jazz drummers may also
monitor their tempi by briefly reverting to a consistent pattern or backbeat.
a drumhead is struck, vibrations radiate from its center and travel across it.
The supplied Velcro MUST be used on a drumhead to elevate the REF and
transmit vibration to the “sweet spot” at the center of its back surface. To
maximize transference and sensitivity use only a 1-inch square patch of Velcro
on both surfaces. Both surfaces must be clean and dry before applying the
Velcro. Press several times with a firm rocking motion when attaching your REF.
Adjust the threshold to only respond to accented beats. Tempo REF will
function properly on a drum only when it and its sensor are attached EXACTLY as
you’re seeing a “ 1” here
because of double triggering, raise the threshold a bit. A vibrating drumhead is
an extremely hostile/dirty environment when trying to convert this sustained
motion into a single digital pulse and a little muffling is a good thing in this
situation. Hard hitters don't need maximum sensitivity and should use
larger Velcro strips to ensure attachment. The REF should be located as far out
to the rim as your playing volume will allow to avoid being struck.
IN A NUTSHELL
doesn’t get any easier than 1-2-3!
1. Hold a button down to get to the desired preset and release.
2. The tempo stored in that preset will flash and beep for 1
minute. 3. Change a stored tempo while the apostrophe is on.
Once a button is pressed and released, if
uninterrupted, the automatic mode step-down sequence is:
CHANGE TEMPO ®
a kick-off tempo or metronome is needed there are 66 programmable presets
available. P: 1 thru P:65 are 1-minute kickoffs and P:66 is a 20-min. standard
metronome. Press and release either button. You'll see P:## (# = number); this
is PRESET MODE. After 1 second this will change to ##’#. Notice
the apostrophe over the center and right digits; this is CHANGE TEMPO MODE.
The apostrophe will extinguish after 1½ seconds, then KICKOFF MODE lasts
to other presets by holding down either button. The number slowly steps 5 times
then goes faster to quickly get you to a distant preset. Release the button when
you're within 5 numbers of your target and again slowly step to it and release.
If you go past it just press the other button. Stepping loops in both
directions; i.e. P:66 increments to P: 1, and P: 1 decrements to P:66.
a button is released the REF waits 1 second for any additional stepping and then
exits to CHANGE TEMPO MODE.
CHANGE TEMPO MODE
CHANGE TEMPO MODE, indicated by an apostrophe,
is automatically entered from PRESET MODE; and as long as the apostrophe is lit
this is your opportunity to change the tempo stored in any preset. So while the
apostrophe is lit, press and hold either button. The number will again slowly
step 5 times then go fast. Range in this mode is 10 to 254 bpm (P:66 = 40 to 208
bpm). Stepping loops in both directions; i.e. tempo 254 increments to 10, and 10
decrements to 254. All preset tempi are set to 111 from the factory. When a
button is released the REF waits 1½ seconds for any additional changes and then
exits to KICKOFF MODE.
number will flash at the displayed bpm for 1 minute (P:66 = 20 min.) in this
mode unless interrupted by a tap or button press. Notice how the display goes
off halfway through the period? This special feature marks the UP in addition to
the DOWN beat, can be used as a visual tempo doubler, and is very helpful for
kickoffs at extreme largo to grave tempi below 40 bpm. Cool… huh? KICKOFF MODE
exits to MONITOR MODE, and if another minute/20 min. is needed, simply
tap either button to restart. Once in MONITOR MODE, the REF will automatically
go to SLEEP after 5 minutes of inactivity. Simply tap to re-awaken.
Settings are retained in memory and retrieved upon wake up. The REF brings you
right back to where you were before it went to sleep.
METRONOME SLAVE UNIT
Plug the patch cord into the REF’s center
jack and the slave unit’s bright or dim jack. Press and release both REF
buttons to toggle the remote strobe and beep. “F
” means strobe & beep ON, and “-
” means strobe & beep OFF. They CANNOT be toggled
separately. The toggle is executed upon exit to PRESET MODE. To
force the REF to sleep max the threshold fully CCW (off) then hold both REF
buttons for 3 seconds. (This does NOT
execute a flash toggle even though the display indicates so.)
Link slave units in a chain if needed. (Only the end slave can be dim.)
up a P-numbered list of songs with respective tempi and keep it handy. *Do
not place your REF directly over a drum's internal muffler. Use of any muffling
device (rings, pads, tape, …etc.) will naturally inhibit skin vibration and
obviously decrease REF sensitivity. *To keep the REF in KICKOFF/METRONOME
while playing a drum, max the threshold fully CCW so it doesn’t trigger out of
this mode. *Store your REF with nothing pressing buttons (or
you’ll kill the batteries) and threshold max’d CCW(off).
(Greatly extends battery life.) *Remove
batteries if storing REF for extended period.
at any time your REF functions improperly or loses presets, reset the unit by
removing BOTH batteries and reinserting. Correct booting is indicated
by 111 at every preset and steady, stable
monitoring. Verify this before replacing the cover. When this remedy
fails or needs to be repeated it’s time to replace batteries. Never replace
just one battery. A weak battery will ruin a good one, so you need to quickly
replace the second battery. Always discard used cells. A used cell may test
“GOOD” but won’t have much in reserve.
Not to worry! Your REF will never just go dead
on you. It uses large capacity lithium coin cells that can last up to a year+
before your REF will begin to malfunction. When the batteries get weak the REF
will trigger very easily and you’ll have to start increasing threshold to
correctly “track” taps. The REF is telling you its batteries should be
replaced soon. These batteries have a 10-year shelf life at room temperature.
Weak batteries will not affect accuracy, only triggering threshold, memory and
LED brightness. Unscrew the back cover, SLOWLY AND CAREFULLY LIFT THIS COVER!
Sensor, wires and foam should remain attached to the cover. Another special
design feature is the use of 2 batteries in parallel. This allows you to replace
one battery at a time and avoid reprogramming the unit. With a small
screwdriver, carefully pry up between a battery and its holder tabs at the
bottom, negative(-) end, pushing the cell against the holder’s two metal
fingers on the opposite, positive(+) end. Do not pry up on the battery
Slide the new cells in against the same metal fingers at the positive end first, and then push down on the negative end. They'll noticeably snap into position. Check for proper function then replace the cover being careful not to over-tighten screws or pinch wires. Use only CR2450 cells. Others won’t properly fit the holders, can damage them, and may cause your REF to malfunction.
