requirements for the Low Voltage Directive (2006/95/EC) and the EMC Directive (2004/108/EC).
Input and Output
Connect your instrument to the input and connect the output to the amplifier.
The Time After Time can be powered from any regulated 9VDC power supply capable of
providing a minimum of 75mA. The rear panel POWER jack is a standard 2.1mm DC
power jack, center negative connection.
Connect the MIDI IN of the Time After Time to the MIDI OUT of your MIDI controller, or
to the MIDI OUT of the last device in the MIDI chain. Additional MIDI devices can be
connected from the MIDI THRU of the Time After Time.
In its default mode, the Time After Time ‘A’ footswitch is used to scroll through the
available presets, while the ‘B’ footswitch is used to enable or bypass the effect. For
other operating modes, see OPERATING MODES on page 6.
The Time After Time uses presets to save and recall settings. A preset consists of all of
the knob settings, including delay time, feedback level, modulation depth, modulation
rate, mix level, and TAP mode setting.
Because the Time After Time is preset based, there are some differences between its
operation and the operation of typical effect pedals. When the Time After Time gets
enabled, it loads a preset from its memory. It does not immediately load the current
settings of the knobs as you see them. The loaded preset settings may be completely
different than the current knob settings.
Once the pedal is enabled, turning a control knob will not modify its parameter until the
knob becomes aligned with the same setting as that of the loaded preset. Once a knob
has been aligned with the preset setting, it becomes “engaged”, at which point it will
function as an active knob.
As you turn the knobs, you may see the display change to a horizontal line. These lines
can be used to locate the positions of knobs as they are saved in the current preset.
The displayed line indicates where the current position of the knob is relative to the
preset, either too high or too low, similar to the way a guitar tuner works.
If the middle line is displayed, then the knob is at the same position as that of the
preset setting. If the top line is displayed, the current knob position is higher than the
preset setting. Turn the knob counter-clockwise to lower the value until the middle line
is displayed. If the bottom line is displayed, the knob position is lower than the preset
setting. Turn the knob clockwise to raise the value until the middle line is displayed.
Once the middle line is displayed, the knob is effectively “engaged” and will operate as
an active real-time control knob.
A quick way to immediately enable the Time After Time and play with its settings is
to press the footswitch and then sweep each knob down and up through its range.
See WORKING WITH PRESETS on page 5 for more details on saving presets.
The following controls are active only when the pedal is engaged. All settings can be
saved as a preset (see WORKING WITH PRESETS on page 5 for more details).
Delay Time controls the amount of time between repeats. Turning the knob clockwise
will increase the time between delay repeats. The available range of delay time is
32ms to 524ms.
When in TAP MODE, turning the Delay Time knob will change the tempo beat division
(see TAP MODE below and on page 8 for details).
Pressing on the DELAY TIME knob toggles the TAP MODE. When activated, the green
LED next to the knob will flash at the rate of the current set tempo. Tap the ‘A’ switch
multiple times at the desired tempo to tap in a new tempo at any time.
TAP MODE can be activated even when the pedal is bypassed. However, when the
pedal gets enabled, the current tempo will only be used if the loaded preset was
previously saved as a TAP MODE preset (see the TAP MODE section on page 8 for
It may seem illogical to be able to tap in a tempo while bypassed only to have TAP
MODE turned OFF when the pedal gets enabled. But, that is exactly what will
happen if the preset you are enabling does not rely on tempo (such as a short
delay) and has not been saved as a TAP MODE preset. Therefore, if you are using
TAP MODE, then you should save at least one preset as a TAP MODE preset (see
the TAP MODE section on page 8 for details).
Feedback controls the amount of output signal that is fed back to the input. This
controls the number of repeats of the delay. The more feedback, the greater the
number of repeats will be heard. Turning the knob fully clockwise will cause selfoscillation.
The MOD DEPTH controls the amount of modulation introduced. Modulation varies the
delay time slightly and can create effects from subtle chorus, to vibrato, to warped out
weirdness. When the knob is turned fully counter-clockwise there is no modulation.
Pressing the MOD DEPTH switch will toggle between two modulation rates, slow and
fast. The exact modulation frequency is a variable of both the MOD RATE setting and
The MIX knob controls the blend between the direct and delayed signals. At its
minimum value, the output is 100% direct (dry). When fully clockwise, the output is
100% delayed (wet). This can be used when using an external mixer, or for stereo
wet/dry amp setups.
The Time After Time has up to 11 available user presets. In its default mode, the ‘A’
footswitch is used to scroll through the available presets, while the ‘B’ footswitch is
used to enable or bypass the effect. For alternative options, see OPERATING MODES
on page 6.
Loading a Preset
When the Time After Time gets enabled, a preset is loaded from memory. The control
settings are taken from the saved preset and not from the physical position of the
control knobs. Therefore, the position of the knobs may not be aligned with the settings
of the loaded preset. For example, the loaded preset may have FEEDBACK set at
11 o’clock, but the physical FEEDBACK knob is set to 3 o’clock.
In order to quickly find the current preset’s settings, the display is used to indicate
knob position. Once a knob starts to rotate, the display will show whether the knob is
set too high or too low, similar to the way an electronic tuner works. The upper line of
the display is lighted if the current knob position is higher than the preset setting, and
the lower line of the display is lighted if the current knob position is lower than the
preset setting. Once the knob position is aligned with the preset setting, the middle line
of the display will light.
Editing a Preset
When turning knobs, the control will not engage until the knob position reaches the
setting of the currently loaded preset. For instance, in the previous example, turning
the FEEDBACK knob will not change the sound until the knob reaches the 11 o’clock
position. Once the FEEDBACK control is engaged, it will behave like an ordinary active
knob. If changes are made to the knob settings from that of the loaded preset, the
yellow PRESET EDITED LED will light.
Saving a Preset
All knob settings can be saved to the current preset number at any time by simply
pressing and holding the DELAY TIME knob for 5 seconds. All of the LEDs will flash to
indicate the preset has been saved.
If a preset is saved with TAP MODE enabled, then tap tempo will be available for the
preset. For example, if a tempo is tapped in while the pedal is bypassed, this saved
preset will then use that tempo when the pedal is enabled (see TAP MODE section on
page 8 for more details).
The Time After Time has up to 11 available user presets. These presets can be loaded
either via MIDI, or by the pedal’s footswitches. There are two available modes for
accessing presets with the footswitches. The mode you use will depend highly on your
performance requirements.
PRESET MODE is designed to give the most accessibility to the presets and TAP
MODE functionality. This is the default factory set mode.
In PRESET MODE, the numeric display indicates the actual preset number. The ‘B’
footswitch is used to enable or bypass the pedal, and the ‘A’ footswitch is used to scroll
through the available presets. When the pedal is bypassed, the display will show the
pending preset number. At that point, if the ‘B’ footswitch is pressed, then that preset
number will be loaded. If the ‘B’ footswitch is pressed again, the pedal will be
bypassed. To load a different preset, press the ‘A’ footswitch to change the pending
preset until the desired preset number is displayed. Press the ‘B’ footswitch to enable
the displayed preset.
It is possible to use the ‘A’ footswitch to go directly from one preset to another preset
without first bypassing. With the pedal enabled, use the ‘A’ footswitch to scroll to the
next desired preset number. Notice that the decimal point will be displayed to indicate
that the displayed preset number is pending (not active). Press the ‘B’ footswitch to
activate the displayed preset.
When using the ‘A’ footswitch to scroll presets, if a pending preset is a
TAP MODE preset, then the tempo LED will flash at the current tempo and
you can use the ‘A’ footswitch to tap in a new tempo. If you wish to use
the ‘A’ footswitch to continue scrolling to the next preset, then the ‘A’
footswitch must be held in order to disable the tap functionality and
increment the preset.
In order to more effectively manage scrolling in PRESET MODE, it is possible to set a
limit on the number of presets used. This cuts down on the need to scroll through
unused presets. For example, if you are only using 3 presets, then when in PRESET
MODE you can use the ‘A’ footswitch to scroll 1, 2, 3, 1, 2, 3, etc. See the GLOBAL
SETTINGS section on page 8 for setting the preset limit.
In BANK MODE, the two switches act like two independent preset switches. Pressing
the ‘A’ switch will toggle the A preset, and pressing the ‘B’ switch will toggle the B
preset. Pressing ‘A’ while ‘B’ is active will switch ‘A’ on and switch ‘B’ off, and viceversa. The In BANK MODE, the 10 user presets are accessed in 5 banks of 2 presets,
and the current bank number will be displayed. In order to change banks, press and
hold the MOD DEPTH knob and then press ‘B’ to increment the bank, and ‘A’ to
decrement the bank.
The Time After Time has two options for pedal bypass type.
True bypass uses a relay to bypass the effect. When the pedal is off, there are no
active electronics in the signal path, and all effect is cut off.
Tails spillover bypass keeps the direct, dry signal path active even when the effect is
bypassed. This allows the delay tails or trails to spillover and ring out even after the
pedal is bypassed.
Changing the Operating Mode, Preset Limit and Bypass Type
The Time After Time is initially set to PRESET MODE. To change the mode settings,
disconnect the power from the pedal. Press and hold the ‘A’ footswitch while applying
power to the pedal. The display will indicate the current mode setting, ‘P’ (PRESET) or
‘b’.(BANK). Use the ‘B’ footswitch to change this setting as desired.
To change the preset limit when using PRESET MODE, first select PRESET MODE with
the ‘B’ footswitch so that the display shows P. Then, press the DELAY TIME knob to
display the current preset limit. Press and turn the DELAY TIME knob to change the
limit from 2 to 0 (0=11). For example, setting the preset limit to 4 will limit PRESET
MODE access to only presets 1-4.
To change the bypass type, press the MOD DEPTH knob to display the current setting.
Press and turn the MOD DEPTH knob to change the setting to rfor relay or tfor tails.
Exit by disconnecting power. Your settings will be saved.
In order to facilitate the mixed use of TAP MODE presets and non- TAP MODE presets
together, the current tempo is treated as a global tempo that all TAP MODE presets will
use. A preset will only use the current tempo if the preset was previously saved in TAP
MODE. Otherwise, it will use the saved delay time for the preset.
When a preset is saved with TAP MODE enabled, the option to tap a tempo will be
available whether the preset is enabled or bypassed. This allows a tempo to be tapped
in prior to activating the preset. For example, when scrolling through the presets using
the ‘A’ footswitch, if preset 3 is showing and it is a TAP MODE preset, then the tempo
will flash and can be modified and tapped.
When in TAP MODE (tempo LED flashing) the ‘A’ footswitch can be used to “tap” in
tempo. The tapped tempo is based around ¼ note = 1 beat. When you tap in the
tempo, you are tapping in quarter notes. But, delay time is not always the same as the
tempo. The tempo can be broken up into musical divisions of the ¼ note beat to create
shorter delay times (1/8, 1/16, etc.).
Once TAP MODE is activated, the tempo will be displayed by the flashing tempo LED.
The DELAY TIME knob can then be used to change the beat division of the delay.
Options include quarter note, dotted 8th, quarter triplet, 8th note, dotted 16th, 8th triplet,
16th note, 16th triplet. Turning the Delay Time knob in TAP MODE will show the current
setting on the display. Because the display is limited to a single character and decimal
point, the beat divisions are displayed in abbreviated form as follows:
BEAT DIVISIONS DISPLAYED = 6. / 6 / 8. / 6. / 8 / 4. / 8. / 4
ACTUAL BEAT DIVISIONS = 16• /16 /8t /16t /8 /4t /8• /4
Unfortunately, this means that in some cases the decimal point in the display
represents a dotted note, and in other cases it represents a triplet. But, if you keep in
mind that the divisions go from smallest to largest, it will help as you change the
The Time After Time, being an analog delay, is limited to a delay time range of 32ms to
524ms. When using TAP TEMPO, there may be times when the combination of tempo
and division would cause the delay time to be outside of the capable delay range. If
this happens, the Time After Time automatically shifts the beat divisions until the delay
time comes within range. For example, if the tapped tempo is 100 BPM and the BEAT
DIVISION is set to ¼ note, then the delay time would be 600ms, which is beyond the
capabilities of the circuit. In this case, the Time After Time would adjust the BEAT
DIVISION to dotted 8th note, which would make the delay time 450ms (within range).
Although the Time After Time has a dedicated switch for activating TAP MODE, the
switch is not designed to be used as a footswitch, and therefore is not a convenient
method for switching on the fly. Instead, the Time After Time is designed to
automatically enable the tap function for presets that are saved in TAP MODE. If you
save preset 2 with TAP MODE active, then the tap function will automatically enable
when the preset appears on the display. For PRESET MODE, this is true both when the
pedal is bypassed and enabled. So if preset 2 is saved as TAP MODE and you are
bypassed with the display showing preset 1, then pressing the ‘A’ footswitch scrolls to
preset 2 and the tap mode becomes active with tempo LED flashing. At that point you
may either tap a tempo with the ‘A’ footswitch or hold the ‘A’ footswitch to increment
scrolling to preset 3. If preset 3 is a TAP MODE preset, the tempo will continue to flash.
If preset 3 is not a TAP MODE preset, the tempo LED will turn off and the tap function
will be disabled.
When used in BANK MODE, the ability to use the tap function when bypassed is not
possible. Since the ‘A’ footswitch is used for toggling the ‘A’ preset, it cannot be also
used for TAP. Because of this, the TAP MODE switch is disabled when bypassed in
However, once a TAP MODE preset is enabled, the tap function and tempo can be
tapped in. If the TAP MODE preset is the ‘A’ preset, then in order to bypass it again, it is
necessary to hold down the ‘A’ switch to deactivate the tap function, and bypass the
preset. For this reason, it is recommended when using a TAP MODE preset in BANK
MODE, that the preset that is TAP MODE is the ‘B’ preset and not the ‘A’ preset.
The signal path in the Time After Time delay utilizes vintage design, bucket-brigade
circuitry. It is what gives it its distinctively warm, vintage, delay sound. But, noise is also
an inherent part of bucket-brigade chips. And for many players, the advent of digital
delay technology was welcomed as a way to clean up their noisy rigs. Unfortunately,
what was also eliminated with the change in technology was the characteristic bucketbrigade sound that many players have grown to love. That sound is why the Time After
Time was designed.
It should be noted that bucket-brigade noise becomes stronger as delay time gets
longer. In addition, the noise will be more noticeable when playing at low instrument
volumes. Maintaining a strong instrument level will help to keep the signal to noise
ratio from becoming too low and the noise becoming more noticeable.
The Time After Time is designed for optimum audio clarity and brightness of the
delayed sound. But, for those users who prefer a darker delayed sound with less high
frequencies, there is an internal trim pot which can be adjusted for setting the tone of
the delayed sound. Because it is not considered a common adjustment, the trimpot is
located inside the pedal on the main circuit board.
To access the trimpot, the top panel must be removed. First, remove the four pot
knobs and four pot nuts. Then, remove the two top panel screws, the two upper rear
panel screws and the two upper rear side panel screws. Remove the top panel and
look for VR13, directly behind the input jack in the upper right section of the circuit
board. Using a small screwdriver, carefully turn the trimpot counter-clockwise to roll off
high frequencies as desired.
There are two ways that the Time After Time can be controlled via MIDI.
Time After Time presets can be recalled using any or all of 128 MIDI Program Changes.
Each MIDI Program Change received by the Time After Time can be mapped to one of
its 11 presets or to bypass. See “Mapping Presets” section below for details.
Real-time control of each of the Time After Time’s parameters can be achieved using
MIDI Continuous Controller messages. MIDI Expression Pedal data can be assigned to
any of the 4 Time After Time knobs as well as the TAP MODE and MOD SPEED
switches. See “MIDI Continuous Controllers” section on the following page.
Setting the MIDI Channel
The Time After Time defaults to receiving MIDI data on MIDI Channel 1. To change the
MIDI channel for receiving MIDI data, first disconnect power from the pedal. Then,
press and hold the ‘B’ footswitch while applying power to the pedal. The current MIDI
Channel will be displayed. Use the ‘B’ footswitch to change the channel. Available
channels are 1-16 (channels 10-16 are indicated as 0-6 with the center yellow LED
lighted). To save and exit, simply disconnect power to the pedal. Your MIDI Channel will
be saved.
Mapping Presets
Any MIDI Program Change can be used to load any preset, or to bypass the pedal. With
a very simple MIDI learning method, you can map the current state of the pedal to an
incoming MIDI Program Change.
First, send any MIDI Program Change to the Time After Time on its set MIDI Channel.
The Time After Time should respond by loading a preset or bypassing. If the Time After
Time is not on the preset you would like, simply use the controls on the Time After Time
to select the desired preset (or bypass it) just as you normally would. However, when
making the selection, continue to hold the footswitch until the LEDs flash, indicating
the MIDI change has been mapped. The Time After Time will now make this selected
change each time that this MIDI Program Change is received.
MIDI Continuous Control
Any of the Time After Time’s knob settings can be controlled in real time using MIDI
Continuous Controllers. The following chart shows the CC#s for the various controls:
0-63=SLOW, 64-127=FAST
So as not to cause a jump in parameter value when receiving MIDI CC data, the Time
After Time will not begin to respond to MIDI CC data until the received CC value is the
same as the current value of the corresponding control.
MIDI Clock
If the Time After Time is in TAP MODE, it will sync to incoming MIDI Clock messages. It
will only sync to MIDI Clock tempo messages. The Time After Time will not respond to
MIDI Start, Continue, Stop or MIDI Time Code commands.
MIDI Clock and tap tempo both control the same global tempo of the Time After Time.
Therefore, if you tap in a tempo and then a MIDI Clock is recognized on the MIDI input
channel, the MIDI Clock will override the tap tempo. Likewise, if MIDI Clock is stopped,
tap tempo will control the global tempo.
