DELAY Knob — Sets the delay time from 52 mS to 1100 mS. As you
turn the DELAY knob clockwise, the delay time will increase. If you tap
in the delay time, the DELAY knob’s setting will be ignored until you
move it again. If you turn the DELAY knob after tapping in a delay time,
the DELAY knob’s setting will supersede the last tap tempo that was
entered. Turning the DELAY knob, while listening to your echoes, will
bend the pitch of your notes. The DELAY knob can also be used to set the
maximum delay time for expression pedal control. N.B.: the TAP DIVIDE
button functions have no effect on the DELAY knob; pressing this button
when the DELAY knob controls the delay time will not change the delay
FEEDBACK Knob — Controls the amount of signal that is
circulated from the output of the delay block to its input. Turning the
FEEDBACK knob clockwise increases the number of echoes. Setting the
FEEDBACK control to its maximum
clockwise position will cause the DMMTT to run-away, or self-oscillate.
Alternatively setting the FEEDBACK knob to its minimum position will
yield just one echo or repeat for each of your notes. The FEEDBACK knob
is also used to set the maximum amount of feedback for expression pedal
DEPTH Knob — Sets the amount of modulation that is applied to
the delay time. As you turn the DEPTH knob clockwise, the amount of
modulation increases. Turn the DEPTH down to the full Counter-Clockwise
(CCW) setting to turn modulation off. The DEPTH knob is also used to set
the maximum amount of modulation for expression pedal control.
RATE Knob — The RATE knob’s main function is to set the rate
or speed of modulation. As you turn the RATE knob clockwise the
modulation rate will increase. The DEPTH knob must be set above the full
CCW position to hear the RATE knob change modulation speed.
Additionally the RATE knob sets the maximum rate of modulation for
expression pedal control.
GAIN Knob — Sets the input gain for the DMMTT. As you turn the
GAIN knob clockwise, the input gain will increase. The total gain range
is -13 dB to +20 dB. The gain block is the first stage that the input
signal goes through in the circuit. Both the dry and wet signals mixed
by the BLEND knob go through the gain block.
BLEND Knob — The BLEND knob is a wet/dry control allowing you
to vary the mix between direct and delayed signals at the OUTPUT jack of
the DMMTT. Set the BLEND knob to the full clockwise position for an
output that is 100% wet. Set the Blend knob to full counter-clockwise
for an output that is 100% dry. Setting BLEND anywhere in between will
mix the wet and dry signals together. Additionally the BLEND knob sets
the maximum wet/dry mix for expression pedal control.
SWITCHES & LEDs
BYPASS Footswitch and STATUS LED — The BYPASS FSW is used to
toggle the DMMTT between effect mode and true bypass mode. The red
STATUS LED will light up when in effect mode and turn off in bypass.
EXP. MODE Button and LEDs — The EXP. Mode button cycles
through the six available expression modes: BLEND, RATE, DEPTH,
FEEDBACK, DELAY and OFF. Each time you press the EXP. MODE button the
DMMTT will advance to the next expression mode LED. An expression pedal
must be plugged into the EXP. PEDAL jack to make use of these modes. A
lit LED for one of the modes indicates the expression pedal will control
that parameter. For example, if the RATE LED is lit, the expression
pedal controls the modulation rate, from slowest (expression pedal = toe
up), to the RATE knob’s current setting (expression pedal = toe down).
When no EXP. MODE LEDs are illuminated the expression pedal is disabled
while it remains plugged into the DMMTT. The setting for the EXP. MODE
is saved and recalled when power cycling.
TAP Footswitch — The TAP FSW is used to tap in the delay time.
Stomp on the TAP FSW two times and the delay time will jump to the time
between taps (if all the TAP DIVIDE LEDs are off). If you tap more than
twice, it will average the tap tempo for all taps, it will stop
averaging if there is more than 2 seconds between two consecutive taps.
The DMMTT will always take into account the TAP DIVIDE setting when
determining the delay time from the tap tempo. For example, if your tap
time is 1 second and TAP DIVIDE is set to eighth notes, the actual delay
time will be 0.5 seconds. The maximum delay time, when tapped in, is
1.5 seconds; though at this delay time the effect will sound quite
lo-fi. The DMMTT will save and recall the tap tempo when power cycling.
In addition, if an expression pedal is controlling the delay time, the
Tap Tempo and TAP DIVIDE setting will determine the maximum delay time
of the expression pedal.
N.B.: The delay time for the DMMTT is always set by the last
method used. If you tap in a delay time, the DELAY knob’s setting is
ignored. After tapping in a delay time, if you turn the delay knob, the
tap time will be forgotten and replaced by the current position of the
TAP FSW HOLD TO PRESET FEEDBACK — If you press and hold the
TAP FSW, the DMMTT will slowly ramp up to a high FEEDBACK setting. After
releasing the held TAP FSW, the feedback amount ramps back down to the
current FEEDBACK knob setting. The high feedback setting that the DMMTT
ramps up to is set at the factory but may be adjusted when you are
holding down the TAP FSW, if held for more than 1 second. If you do not
like the setting chosen at the factory, simply turn the FEEDBACK knob to
your preferred setting, while the TAP FSW is held down. It may take a
few tries before nailing the perfect setting. Release the TAP FSW to
save the feedback hold setting. The DMMTT will remember the TAP FSW HOLD
setting after power cycling.
If you want to restore the original factory setting for the FEEDBACK
HOLD, press and hold the EXP. MODE button while applying power to the
DMMTT. When you see all 5 expression mode LEDs light up, the factory
setting has been restored, you can now release the EXP. MODE button.
BEAT LED — The green BEAT LED either blinks at the current
delay time setting (if delay time is set by the DELAY knob) or the tempo
that you tapped in. Cycling through the TAP DIVIDE settings will not
change the BEAT LED blink rate. If you are modulating the delay time,
the change in delay time due to modulation will be reflected in the BEAT
TAP DIVIDE Button and LEDs — This button cycles through the
six possible settings for TAP DIVIDE. Each setting, except when all LEDS
are off, will divide the tap tempo to create shorter delay times in
sync with your original tempo. It works like so: The DMMTT always
assumes that the musician taps in a quarter note. That quarter note can
then be divided down to five other types of notes: dotted eighth note,
quarter note triplet, eighth note, eighth note triplet and sixteenth
note. The sixth mode is quarter note or OFF, where the tap tempo is not
divided down and the delay time is set to your actual tap time. No LEDs
are lit when Tap Divide is set to quarter note/OFF. Below is a chart
displaying the six modes, their divide ratios and an example of the
delay time for each mode:
|TAP DIVIDE MODE
||DELAY TIME (for a 600 mS TAP)
|Quarter Note / OFF
|Dotted 8th Note
|Quarter Note Triplet
|8th Note Triplet
N.B. The TAP DIVIDE button has no effect on the delay time when
the delay is set by the DELAY knob. Cycling through the different TAP
DIVIDE modes, when the delay time was last set by the DELAY knob, will
not change the delay time in any way.
The TAP DIVIDE button setting is saved and recalled when power cycling.
TAP DIVIDE SEQUENCE MODE — The DMMTT contains a little easter
egg called Tap Divide Sequence mode. In this mode, the DMMTT will
automatically cycle through the six tap divide modes at a rate set by
the RATE knob. To use this mode, do the following:
1. Tap in a delay time. Tap Divide Sequence mode will not work if the delay time is set by the DELAY knob.
2. Press and hold the TAP DIVIDE button for 2 seconds. After 2 seconds,
all of the TAP DIVIDE LEDs will light up briefly, now you are in
sequencer mode. You can release the button.
3. Turn the RATE knob to change the speed of the sequence. You should see the tap divide LEDs light up in a sequential fashion.
4. You can tap in new delay times to change the delay time range.
5. To exit Tap Divide Sequence mode: hold down the TAP DIVIDE button for
another 2 seconds. All 5 LEDs will light briefly to indicate you have
exited sequence mode. You could also simply turn the DELAY knob.
I/O & POWER JACKS
INPUT Jack — Connect the output of your instrument or other
effects pedal to the ” INPUT jack. The impedance presented at the INPUT
jack is 100 kï�—.
OUTPUT Jack — Connect the output of the DMMTT to the input of an amplifier or another effects pedal. The output impedance is 200 ï�—.
SEND Jack — Connect this jack to the input of another effects
pedal or chain of effects pedals to insert an effects loop before the
DMMTT’s delay block.
RETURN Jack — Connect this jack to the output of another
effects pedal or chain of effects pedals to insert an effects loop
before the DMMTT’s delay block. The input impedance presented at the
RETURN jack is 2 Mï�—.
EFFECTS LOOP — The Deluxe Memory Man w/ Tap Tempo has an
effects loop feature which allows other effects to be inserted into the
feedback loop of the delay block, before the bucket brigade chips. This
means that you can put additional effects on your wet signal without
changing your dry signal and each time your notes go around the feedback
loop, they will also go through the effects loop.
For example, if you connect a Micro POG in the DMMTT’s effects loop,
setting the Micro POG to output only the upper octave, the delayed note
will be one octave above the dry note that you played. Additionally,
with a fair amount of feedback on the DMMTT, each time the note circles
around the delay loop, the signal will go up another octave. So if you
play a C2 on the guitar, the first echo will be a C3, the second C4, the
third C5 and so on.
Another example would be to plug a volume pedal into the DMMTT’s
effects loop. The volume pedal will act as a FEEDBACK control. With the
addition of an expression pedal, you could have two pedals controlling
parameters on the DMMTT.
To properly use the DMMTT’s effects loop, connect the SEND jack to
the input of your effects loop and the RETURN jack to the output of your
N.B. If you do not wish to use the effects loop, please leave the RETURN jack disconnected.
EXP. PEDAL Jack — Enables the musician to control any of the
five available expression modes with an optional expression pedal or
control voltage. The expression pedal should have a Tip-Ring-Sleeve plug
attached to it. It is important that the expression pedal have the
correct polarity. The tip of the plug must be connected to the wiper of
the potentiometer inside the expression pedal. If you are not sure what
type of expression pedal to use, try to purchase one with a polarity
switch so that it will work with many different types of instruments.
Some suggested Expression Pedals: M-Audio EX-P, Moog EP-2, Roland EV-5
or Boss FV-500L. You may also connect a control voltage on TS plug to
this jack. The Control Voltage range must be 0 V to 5 V.
EXPRESSION PEDAL CONTROL — The Deluxe Memory Man w/ Tap Tempo
allows external control over five of its parameters: BLEND, modulation
RATE, modulation DEPTH, FEEDBACK and DELAY time. Please see the EXP.
PEDAL Jack section above for suggestions on the type of expression
pedals to use. The pedal will need to have a TRS plug. In addition you
may use a control voltage, with a TS plug. The acceptable CV range is 0 V
to 5 V.
Use the EXP. MODE button to choose the knob you want to control with
an expression pedal; repeatedly press and release the EXP. MODE button
until the proper LED lights. After selecting a parameter, its associated
knob will now set the maximum sweep range, which is the toe down
position for the expression pedal. For example, if you want to sweep the
full range of the FEEDBACK knob, you will need to set the FEEDBACK knob
to its full clockwise position. The expression pedal will then sweep
from 0% feedback (toe up position) to 100% feedback (toe down position).
Some expression pedals allow you to dial in the toe up position using
an extra knob on the pedal itself. When using this type of pedal you
can set the range for both toe up (using the knob on the expression
pedal) and toe down (using the selected knob on the DMMTT). If you use
an expression pedal that does not allow you to dial in the toe up
position, then toe up will always be that particular knob’s minimum
TAP SW Jack — Allows the musician to input the tap tempo from
an external momentary switch. The external switch should be normally
open. Upon engaging the switch, it should create a short circuit between
the Tip and Sleeve of the plug inserted into the TAP SW jack on the
DMMTT. Releasing the switch should open the circuit between the Tip and
Sleeve. The TAP SW jack is connected in parallel with the TAP FSW on the
DMMTT so they can both work at the same time. A suggested Momentary
Footswitch that has been tested with the DMMTT is the Boss FS-5U
Momentary Foot Switch.
TAP SW Jack Extra Control — If you are handy with a soldering
iron, you may also make connections on the DMMTT’s PCB to allow external
control of either the TAP DIVIDE button or the EXP. MODE button by
connecting an external momentary switch between the Ring and Sleeve of
the TAP SW jack.
To enable external control of the TAP DIVIDE button, short together
the pads of R139 on the DMMTT PCB. R139 is labeled TAP DIV SW and is
located just above the 10-Pin IDC header, CN6.
To enable external control of the EXP. MODE button, short together
the pads of R140 on the DMMTT PCB. R140 is labeled EXP FUNC SW and is
located above the 6-Pin IDC header, CN5.
These external switch connections work in parallel with their
associated buttons on the DMMTT. If either of the buttons have been
enabled for external use, a TRS plug must be inserted into the TAP SW
jack. In this circumstance, if a TS plug is inserted into the TAP SW
jack it will be equivalent to holding down whichever button has been
enabled for external use, without the ability to release the button.
9V PWR JACK — Connect the output plug of the supplied AC
Adaptor into the 9V power jack at the top of the DMMTT. The DMMTT’s
current requirement is 200mA at 9VDC. The polarity of the power jack is
center negative. The maximum allowable power supply voltage is 10.5 VDC.
The Feedback Hold setting, along with the original EXP. MODE and TAP
DIVIDE mode, can be restored to their original factory settings by
holding down the EXP. MODE button during start up.
Press and hold the EXP. MODE button, then apply power to the DMMTT
while continuing to hold the EXP. MODE button. Once you see all five
EXP. MODE LEDs light up solid, you may release the button. The factory
settings have been restored.
