Restoring Factory Presets
DL4 MkII is pre-programmed with a set of great factory presets at birth, containing
six unique settings within the presets A~F locations. The MIDI-accessible preset
locations, 7~128, include a common preset, which differs from the six A~F factory
presets (also, see "" on page 16). All factory presets are over-written with your
custom settings whenever you perform a preset save. Should you ever wish to restore
the factory presets—and erase the sounds you might have saved in any of the
128 preset locations—you can perform a Factory Restore.
1. Press and hold both the A and TAP footswitches while connecting the
power adapter to the DC IN.
2. Continue to hold the switches for approximately 8 seconds, until you
see the green LEDs light up.
Your DL4 MkII device is restored with all factory presets and original default global
settings.
About Tap Tempo
As you’ve likely surmised by now, you can set a tempo on your DL4 MkII simply by "tap-
ping" on the TAP footswitch rhythmically a few times —you’ll see the TAP light flash to
indicate the current tempo. But you may be wondering what all this fuss is about "Tap
Tempo" and "Note Subdivisions," and why you might want to use them.
In the early days, when tape and mechanical echo units first roamed the Earth, engi-
neers in lab coats had to manually calculate the correct delay time for the tempo of a
song by dividing 60,000 into the tempo to determine the 1/4 note delay value. From
there they could calculate all of the wonderful possible rhythmic subdivisions, using a
multiplier table like this:
1/4 Note Delay Time Multiplier Table
Note Value Multiplier Note Value Multiplier
Whole Note 4 Dotted 1/8 .75
Dotted 1/2 3 1/8 Note .5
1/2 Note 2 Triplet 1/8 .333
Triplet 1/2 1.333 Dotted 1/16 .375
Dotted 1/4 1.5 1/16 Note .25
1/4 Note 1 Triplet 1/16 .167
Triplet 1/4 .667
When slathering your signal with spacious delay, it is often most pleasing to hear those
repeats in sync with the song’s tempo—and perhaps at a specified note value subdivi-
sion (like the ubiquitous dotted 1/8th note salvo employed by The Edge).
Fortunately, no calculators or math are required with DL4 MkII. By default, all delay
models are configured so that you’ll see the TAP switch’s LED flashing at 1/4 note
subdivisions of the current Tap Tempo. If you stomp several times on the TAP switch,
counting in 1/4 notes, this changes the current Tap Tempo and your repeats dutifully
follow. When you change to a different delay model, you’ll see the tempo changes to
the new model’s default delay time (unless you’ve set a note subdivision, or changed
to the Global Tempo option—see the following sections for all about those topics).
Note Subdivisions
To change to a different note subdivision of the tempo, press-hold the ALT/LEGACY
button while turning the TIME/SUBDIV knob to the selected note value on the knob label.
+
Press-hold ALT/LEGACY button and turn TIME/SUBDIV knob to choose a note subdivision
The red TAP light continues to flash at the 1/4 note of the current Tap Tempo for reference,
but you’ll hear your delay repeats at the selected subdivision of the current tempo. Once
you’ve set a note subdivision, your specific tempo and selected note subdivision will
not change when selecting a different a different delay model within your current preset.
If you prefer to just return to just setting your tempo "by ear," simply turn the TIME/
SUBDIV knob (without touching the LEGACY button) to exit the “note subdivision mode”
and adjust your delay time manually. The red TAP light returns to flashing at 1/4 notes
of your new tempo rate for reference.
Per Preset or Global Tempo
By default, the current Tap Tempo is stored and recalled individually Per Preset. If
you prefer, you can change this behavior to Global, by way of the Global Settings >
"Tempo Preset/Global" option, so that your Tap Tempo remains unfettered across preset
changes, until you change it again manually.
