In math:

Time switch up:

Delay time = ([Knob x CV] + 16) x beat time

Time switch center:

Delay time = (Knob x CV)

Time switch up:

Delay time = ([Knob x CV] / 8) x beat time

"Knob" ranges from 1 to 16

"CV" ranges from 1 to 16 if positive voltage is applied to the Time CV jack (0 to +5V)

"CV" ranges from 1 to 1/16 (0.0625) if negative voltage is applied to the Time CV jack (0 to -5V)

Note that with 0V on the CV jack (nothing plugged in), CV=1, so it has no effect on the knob's setting.

For example, tap a tempo of 0.5 second. This makes one beat be ½ second (120BPM).

Set the Time knob to 8, and the Time switch to center. If there is no CV plugged in, the delay time will be 8 beats, or 4

seconds.

Now flip the Time switch down to "1/8", the delay time will be eight 1/8th notes, or ½ second.

Now turn the Time knob down to "2", and the delay time will be two 1/8th notes or 0.125 seconds.

Now flip the Time switch up to "+16" and the delay time will be 18 beats, or 9 seconds.

Now apply some CV, the Time will get slower as you apply positive CV, and faster as you apply negative CV.

Setting two channels to different delay loop periods that are multiples of the same clock can result in very interesting phasing

arrangements!

Loop start and stop points

When Infinite Hold is on, changing Time will change the loop start point in order to make the loop the new length. If you hold

down the Reverse button while changing Time, you will change the loop end point. You also can use this to change a loop

that's, for example, 4 beats long into one that's 5 beats long, in two different ways (adding a beat to the end, or to the

beginning). There are many creative possibilities to be explored with adding and subtracting from the beginning and/or end of

a loop. One idea is to "inchworm" up and down memory. If you want to move more quickly than an "inchworm", try windowing:

see the section below on Windowing.

Delay Feed

Delay Feed is the amount of signal from the In jack that's recorded in memory. You can think of it as "Record

Level" or "Input Level", but there is one important detail to remember:

Delay Feed doesn't effect the Dry signal (which is what's present on the Out jack when the Mix knob is set to

Dry). It just effects how much signal is laid down or recorded. This detail is intentional because when doing

sound-on-sound techniques, you can play a sound continuously in the Dry channel while modulating Delay

Feed to fade in portions of the signal onto the loop.

The knob and CV jack are added together and have a maximum combined value of 100%. Negative voltage on the CV jack is

ignored. Note that in Inf Hold mode, Delay Feed has no effect since there is no recording.

Feedback

Also known as "regeneration", "echo amount", and other names, feedback is a common feature on delay

effects. Feedback is the amount of signal read from memory that's written back to memory in a different

location. This new location will be read again in the future, and written back again at yet another location in

the future. Take a look at the block diagram on the back page to see how Feedback fits into the signal flow.

On the DLD, Feedback ranges from 0 to 110%.

With no feedback (knob at 0), and you will hear one echo. As you turn Feedback up, you will gradually hear

more and more echoes (the amount of time before the echoes go to silence will increase).

With Feedback at 100%, the signal read from memory is written back to memory unaltered. Thus, the echoes will never fade

out — an infinite loop. But if you input a signal on the In or Return jacks, they will add to the feedback signal, which can result

in the sound gradually getting louder and louder as sound is added but never reduced. The knob's range has been modified

to create a large area which is exactly 100%.

With Feedback at 110%, the signal read from memory is boosted before written. This makes the echoes louder and louder

each time. For short delay times, this is a well-known "blooming echo" effect used in various styles of music including Dub

Reggae.

Note that in Infinite Hold mode, Feedback has no effect. However, see the section below on "Windowing" for the special

usage of the Feedback knob and jack while holding down the Infinite Hold button.

The knob and CV jack are added together, and are have a maximum combined value of 110%. Negative voltage on the CV

jack is ignored. If the knob is set to 0%, then applying a voltage of 5V or greater will cause a Feedback amount of exactly

100%. This is to allow for easy CV control of accessing 100% Feedback (any voltage greater than 5V = 100%, if the knob is

set to 0)

Mix

Mix controls the blend between the Dry signal and the Wet signal on the Out jack. It does not effect the Send

jack. The Dry signal is taken directly from the In jack (and not the Return jack) before the Delay Feed

parameter has any effect. See the block diagram on the back page of the manual.

Mix does not have a CV jack, but starting in firmware v4, there is an option to make the Delay Feed CV jack

control Mix instead (see System Settings section).
