We lc om e
Congratulations on your purchase of the ENSONIQ DP/Pro Professional 24-bit Effects Processor. The
DP/Pro Reference Manual provides descriptions of all of the DP/Pro’s many features, and provides
tips for unlocking the product’s tremendous sonic potential.
Tip: Be sure to check out ENSONIQ’s World Wide Web home page at
<http://www.ensoniq.com> from time to time for the latest info on the DP/Pro and other
ENSONIQ products.
P ar am e t e r s, Value s and Page s
There are three basic terms that underlie every DP/Pro activity, and which must be understood. They
are:
• Parameter—A parameter is any one of the DP/Pro’s programmable attributes.
• Value—A value is a parameter’s setting.
• Page—The DP/Pro’s front-panel buttons provide access to a great many parameters, often
presented one after another on sequentially arranged displays. Each display is called a “page.”
1—Introduction
Tip: A parameter is described by the button with which it’s associated. For example, if a
parameter is referred as a “System/MIDI parameter,” you’ll know that it’s one of the group of
parameters accessed by pressing the System/MIDI button.
N avigat ing t he DP /P r o
It’s simple to navigate the DP/Pro’s pages and perform its operations once you understand the frontpanel tools central to so many of its activities:
• The Next and Previous Page buttons allow you to move forward or back, and across, the
DP/Pro’s pages.
Tip: The Next and Previous Page buttons, when held down, will scroll through multiple
pages.

A Note About Read-Only Displays
Each of the areas within the DP/Pro has its own set of displays, which are described in detail in the
chapters of the DP/Pro Reference Manual. The DP/Pro provides a number of read-only displays for
informational purposes, in addition to its many adjustable parameters. When a displayed value is

Effects
In the DP/Pro, an effect is a preset that contains all of the settings for the DP/Pro’s two processor
chips, as well as the settings that determine the flow of audio into, through and out of the DP/Pro.

The DP/Pro can contain up to 387 effects. Effects are stored in the DP/Pro’s memory in four banks:
• Banks 0 and 1 are RAM banks that can be used for the storage of effects you edit and create.
• Banks 2 and 3 are ROM banks that contain effects programmed by ENSONIQ; these effects are
always available and uneraseable.
Effects can be selected using the DP/Pro’s Select Effect button and the Value knob, with a foot switch
(such as the ENSONIQ SW-10) or with Program Changes and Bank Select messages received via
MIDI.

The DP/Pro’s Two ESP2 Processor Chips
The basic building blocks of DP/Pro effects are two of ENSONIQ’s second-generation 24-bit ESP2
custom VLSI chips. “ESP” is an acronym for “ENSONIQ Signal Processing.” The two chips are called
ESP-A and ESP-B.
Each ESP uses an algorithm—a highly specialized digital signal processing program—to perform an
audio processing task. The DP/Pro contains 42 different algorithms, any of which can be used by
either ESP. Each algorithm offers its own set of useful presets, called variations.

Algo B Params B Mod B Bypass B
Edit
Algorithm and variation selection occurs after pressing the Algo A (for ESP-A) and Algo B (for ESP-B)
buttons. Chapter 5 explains in detail the manner in which algorithms and variations are selected.
Each algorithm contains a comprehensive suite of parameters, accessed via the Params A and Params
B button. Algorithms parameters are described in Chapter 6.

Algo B Params B Mod B Bypass B

In addition, each ESP contains its own set of mix-related parameters that govern the ESP’s
input/output levels, stereo balances and, where applicable, its feedback settings. The mixer
parameters are also found under the Params A and Params B buttons. The ESP-A and ESP-B Mixer
Params are described in Chapter 8.

Fast Editing of Parameters
The DP/Pro’s Tweak parameters system offers the ability to bring your most-commonly used ESP mix
and algorithm parameters up to the DP/Pro’s front panel. This provides quick access to these
parameters for editing without requiring you to navigate through all of the parameters available for
each ESP and algorithm. Chapter 9 describes the setup—via the Params A and Params B buttons,
shown above—and use—via the Tweak button—of Tweak parameters.

The DP/Pro offers a range of bypass options that allow you to control what it means to “turn off” an
ESP. These options are described in Chapter 2.
Copying and Swapping Algorithms
The DP/Pro provides a selection of tools for moving algorithms and their settings from one ESP to
another, or between effects. These tools, available under the Routing button (shown below), are
described in Chapter 7.
ENSONIQ DP/Pro Reference Manual 5
1—Introduction
Routing
The DP/Pro provides a variety of ways in which you can pass audio into the DP/Pro, through the
ESPs, and back out again. This is referred to as signal routing.
• You can process audio sent into the DP/Pro’s left and right inputs as a single stereo feed, or as
• When you process stereo audio, you can arrange the two ESPs so that signal passes through them
• You can also determine whether the stereo outputs of the ESPs will be mixed together, presenting

Real-Time Effect Modulation
The DP/Pro provides an extensive set of tools that allow for the real-time manipulation, or modulation,
of effects. The Mod A and Mod B buttons are provided for this purpose.
Algo A Params A Mod A Bypass A
Routing
Algo B Params B Mod B Bypass B
The setting of any ESP mix or algorithm parameter can be controlled in real-time. Real-time
modulation can be performed using any MIDI controller, a stereo foot switch, a CV pedal or the
DP/Pro’s unique virtual controllers, its Tweak knobs, or mod LFOs.
The Virtual Tweak Knobs
Each effect in the DP/Pro contains two virtual controllers called Tweak Knob 1 and Tweak Knob 2.
These two devices are software objects that, when enabled, are controlled by the front-panel Value
knob. The tweak knobs can be used for the modulation of any ESP mix or algorithm parameters in
either ESP, and can be assigned names in order to help you keep track of what it is you’ve
programmed them to do.
Edit
The Mod LFOs
In addition to the LFOs available within the DP/Pro’s algorithms, two free-standing LFOs are
available at all times for use as real-time modulators of ESP mix and algorithm parameter settings in
either ESP: the mod LFOs. These LFOs can provide cyclical changes to parameters’ settings, as they
cycle back and forth through their low-frequency waves.
Real-time effect modulation, the tweak knobs and mod LFOs are described in detail in Chapter 9.

Synchronizing Effects to a Tempo
Many of the DP/Pro’s algorithms contain elements that can be synchronized to a timing reference. The
DP/Pro contains a system clock to provide such a pulse. The system clock can be set to be internally
controlled or to respond to received MIDI clocks. When the system clock is not linked to an external
MIDI timing source, its rate may be set manually, or by tapping the desired tempo on the front-panel
Tap button. The Tap button—whose LED flashes the current system tempo—is itself highly
configurable. Chapter 2 provides information on the system clock and setting up the Tap button.

Defining your DP/Pro Workspace
The DP/Pro’s overall operation is quite customizable. The System/MIDI button —shown
above—provides access to the many parameters that allow you to make your DP/Pro working
environment comfortable. The System/MIDI parameters are described in Chapter 2.
Important: Two Final Concepts
Downloading and Installing
In the DP/Pro, the selection of an effect, algorithm or algorithm variation does not necessarily mean
that it’s ready for use:
• When an effect is selected, the DP/Pro must be instructed to download all of the effect’s
algorithm settings into its ESPs, and to configure the effect’s signal routing.
• When an algorithm or algorithm variation is selected, the DP/Pro must be instructed to
download all of the algorithm’s settings into the selected ESP.
The DP/Pro allows you to choose whether you’d like it to download, or install, these objects as they’re

selected, or whether you’d like the option of installing effects and/or algorithms (and variations)
manually by pressing the Enter button after you’ve selected them. If you choose the latter, the Enter
button will flash after you’ve selected an effect, algorithm or algorithm variation to remind you that it
needs to be pressed.

Powering Up the First Time
The correct procedure for powering up the DP/Pro for the first time is as follows:
1. Make sure the DP/Pro’s power button is turned off—the bottom of the button should be pressed
in.
2. Plug the provided line cord into the AC line receptacle on the rear panel of the DP/Pro.
3. Plug the other end of the line cord into a grounded AC outlet.
4. Press the top of the Power button on the right side of the DP/Pro’s front panel.
Powering up the DP/Pro in a MIDI Configuration
In a series of MIDI devices, you should always turn on the device that’s transmitting MIDI data
(keyboards, sequencers, etc.) before you power up the device that’s receiving MIDI data. For instance,
if you’re using the DP/Pro to receive MIDI information from a keyboard or sequencer, you should
turn the keyboard or sequencer on before the DP/Pro. This prevents any unwanted MIDI information
MIDI
8 ENSONIQ DP/Pro Reference Manual
1—Introduction
from being “spit” out of the transmitting device during power up, which could confuse or disable
your DP/Pro. If this should happen, turn off the DP/Pro, and then turn it back on.
Polarization and Grounding
Like many modern electrical devices, the DP/Pro has a three-prong power cord with earth ground to
ensure safe operation. Some products have power cords with only two prongs and no earth ground.
For safety, some of these products have polarized plugs which can only be inserted into an outlet the
proper way.
Three-prong
PolarizedNon-polarized
Some products, such as older guitar amplifiers, do not have polarized plugs and can be connected to
an outlet incorrectly. This may result in dangerous high voltages on the audio connections, which
could cause you physical harm, or damage any properly grounded equipment to which they are
connected, such as your DP/Pro.
To avoid shock hazards or equipment damage, we recommend the following precautions:
• If you own equipment with two-pronged power cords, check to see if they’re polarized or nonpolarized. You might consider having an authorized repair station change any non-polarized
plugs on your equipment to polarized plugs to avoid future problems.
• Exercise caution when using extension cords or plug adapters. Proper polarization should always
be maintained from the outlet to the plug. The use of polarized extension cords and adapters is
the easiest way to maintain proper polarity.
• Whenever possible, connect all products with grounded power cords to the same outlet ground.
This will ensure a common ground level to prevent equipment damage and minimize hum in the
audio output.
AC outlet testers are available from many electronic supply and hardware stores. These can be used to
check for proper polarity of outlets and cords.
with earth ground
For more information on grounding the DP/Pro, see Chapter 12.
AC Line Conditioning
As with any computer device, the DP/Pro is sensitive to sharp peaks and drops in the AC line voltage.
Lightning strikes, power drops, or sudden and erratic surges in the AC line voltage can scramble the
internal memory, and in some cases, damage the unit’s hardware. Here are a few suggestions to help
guard against such occurrences:
• A surge/spike suppressor—this absorbs surges and protects your gear from all but the most
severe over-voltage conditions. You can get multi-outlet power strips with built-in surge/spike
suppressors for little more than the cost of unprotected power strips, so purchasing one is a good
investment for all your electronic equipment.
• A line conditioner—this is the best, but by far the more expensive way to protect your gear. In
addition to protecting against surges and spikes, a line conditioner guards equipment against
excessively high or low line voltages. If you use the DP/Pro in lots of different locations with
varying or unknown AC line conditions, you might consider investing in a line conditioner.
Rack Mounting Guidelines
Because the DP/Pro uses an internal transformer, it generates a certain amount of heat. For better
reliability, we don’t recommend the installation of the DP/Pro near devices that are particularly
sensitive to heat, or near power amps, tube equipment, or other products that emit a lot of heat.
ENSONIQ DP/Pro Reference Manual 9
1—Introduction
Temperature Guidelines
The DP/Pro contains computerized and electronic circuitry that can be susceptible to damage when
exposed to extreme temperature changes. When the DP/Pro is brought inside after sitting in a cold
climate (i.e., the back seat of your car), condensation builds up on the internal circuitry in much the
same way a pair of glasses fogs up when you come inside on a cold day. If the unit is powered up as
this condensation occurs, components can short out or be damaged. Excessively high temperatures
also pose a threat to the unit, stressing both the internal circuits as well as the case. With this in mind,
we advise you to follow these precautions when storing, mounting and setting up your DP/Pro:
• Avoid leaving the DP/Pro in temperatures of less than 50 degrees Fahrenheit or more than 100
degrees Fahrenheit.
• When bringing the DP/Pro indoors after travel, allow at least 20 minutes for the unit to reach
room temperature before powering up. In the case of extreme outdoor temperatures (below 50
degrees Fahrenheit or above 100 degrees Fahrenheit), allow an hour or more before powering up.
• Avoid leaving the DP/Pro inside a vehicle exposed to direct sunlight.
Se t t ing A nalog Input Le ve ls
The DP/Pro can accept +4dB or -10dB input levels. The rear panel I/O level switch should be set to

though your DP/Pro battery should last for years, you may eventually need to have it replaced by an
authorized ENSONIQ Repair Station.
The DP/Pro will tell you when its battery needs replacing. It will flash the following when you power
up:
Warning! Main battery is
low. See manual.
This display will appear only briefly, and then allow you to proceed normally. Make sure that
everything in RAM that you’d like to keep—or any special system settings—have been safely stored
on an external MIDI storage device—as described in Chapter 2—and take the DP/Pro to an
authorized ENSONIQ Repair Station as soon as possible to have the battery replaced.
Reinitializing the DP/Pro
All computer-based devices—including the DP/Pro—occasionally experience signs of data
corruption. If your DP/Pro begins acting oddly, you can reinitialize its software to clear out any
problems lurking there.
Warning: Make sure you’ve saved any effects or system settings that you want to preserve to
an external MIDI device before reinitializing. Reinitializing erases the contents of the
DP/Pro’s user memory banks, and resets all System/MIDI parameters to their default values.
To Reinitialize the DP/Pro
1. Hold down the System/MIDI button.
2. While continuing to hold the System/MIDI button, press the Cancel button.
3. Let go of both buttons. The displays shows:

2—System/MIDI Parameters
Se le c t ing t he Type of Audio t o be P r oc e sse d
The first step in using the DP/Pro is determining the type of audio you’ll be sending into its input
jacks. All DP/Pros can process analog audio. Any DP/Pro with an ENSONIQ DI-Pro digital I/O
board installed can also process incoming digital audio in AES and S/PDIF formats.
System/MIDI Parameter 1: Input
k
Input=Analog Clock=48.000
kHz
Values: Analog; Digital, AES; Digital, S/PDIF; Ana+Dig, AES; Ana+Dig, S/PDIF
Default: Analog
Note: The listed values are available when the optional DI-Pro digital I/O board is installed in
the DP/Pro. When the DI-Pro board is not present, only the Analog setting is visible.
What this Parameter Does:
The Input parameter selects the type of audio source you’ll be sending into the DP/Pro. Rear-panel
combination 1/4”/XLR jacks are provided for analog signals, and the optional DI-Pro digital I/O
board provides digital inputs for AES- and S/PDIF-format data.
Est ablishing the D P /P r o’ s Sam ple Rat e
The DP/Pro’s A/D and D/A converters can operate at several different sample rates.
When an analog signal is being processed, the DP/Pro can operate at either 44.100 kHz or 48.000 kHz.
Both rates have their advantages and disadvantages. The 48.000 kHz provides the highest-quality
signal processing. However, should you be using the DP/Pro’s digital outputs to master an analog
signal to CD or some other digital medium that operates at 44.100 kHz, you’ll need to use the same
sample rate in the DP/Pro.
Note: The DP/Pro’s Sample Rate LEDs—located above the auxiliary display—show the
DP/Pro’s current sample rate.
System/MIDI Parameter 2: Clock
Input=Analog Clock=48.000
k
Values: 44.100 kHz (when Input=Analog); 48.000 kHz (when Input=Analog)
Default: 48.000 kHz
2 ENSONIQ DP/Pro Reference Manual
kHz
What this Parameter Does:
The Clock parameter sets or displays the sample rate used by the DP/Pro’s A/D and D/A converters.
The behavior of this parameter is dependent on the setting of the Input parameter.
• When Input=Analog, the setting of the Clock parameter determines the operating sample rate of
the DP/Pro.
System/MIDI parameters 3 through 5 are available only when a DI-Pro digital I/O board has been
installed in the DP/Pro. See the DI-Pro User’s Guide for information on these parameters.
Global MID I Se t t ings
The DP/Pro is a highly MIDI-aware device:
• DP/Pro effects can be selected via MIDI Program Change and Bank Select messages.
• Effects can be modulated in real time using any MIDI controller.
• Many aspects of DP/Pro algorithms can be synchronized to MIDI clocks.
• The DP/Pro generates and responds to System Exclusive data dumps.
• The DP/Pro can transmit control change messages generated by its virtual Tweak knobs, its
Bypass buttons and its dual foot switch.
• The DP/Pro can transmit Program Change messages when effects are selected from the front
panel, or by using a foot switch.
• Various elements of MIDI transmission and reception can be individually enabled or disabled;
the DP/Pro also provides an overall MIDI reception on/off parameter.
• The DP/Pro’s response to Program Change messages can be re-mapped to allow any Program
Change value to select any effect.
The DP/Pro uses three MIDI channels. Program Changes received on the System MIDI channel select
effects, while ESP-A and ESP-B each have their own MIDI channels upon which they receive MIDI
controller messages used for the real-time manipulation of their algorithms.

Many of the DP/Pro’s algorithms contain time-based elements—LFOs and delays, for example—that
can be synchronized to a timing reference. This provides a high degree of timing control of those
elements. The DP/Pro provides its own internal clock for such purposes, or it can synchronize its
algorithms to MIDI clocks received from and external MIDI device.
Tip: The algorithm parameter charts in Chapter 6 of the DP/Pro Reference Guide show which
algorithm elements are capable of synchronization. Any parameter with the letter “T” (for
“Time”) in its Attributes column can be synchronized.
The DP/Pro’s internal clock can be set by manually adjusting the System/MIDI System Tempo

System/MIDI Parameter 27: (App Group) Effect

Values: None; 0000* through 3005
Default: None
What this Parameter Does:
The Effect parameter allows you to assign one of the DP/Pro’s effects to the currently selected item.
Each effect is shown as a four-digit number. The first digit represents the bank in which the effect is
stored. The three remaining digits show the program number of each effect within the selected bank.
If System/MIDI parameter 76 is set to “Yes,” an asterisk following the effect’s bank and program
numbers shows that the memory location is currently empty. ” If parameter 76 is set to “No,” unused
locations will not be available for selection by this parameter.
Gr ouping Ef fe c t s for Easy Se le c t ion
The DP/Pro allows you to group effects together as songs—a DP/Pro song is a list of effects meant to
be selected one after the other. A song can use any of the effects in the DP/Pro, arranged in any order.
There can be up to 10 steps in each song—each step being associated with a single effect—and up to 10
songs in the DP/Pro’s memory at any given time. You can move forward or back through the list by
pressing the pedals on a dual foot switch—such as an ENSONIQ SW-10 (see the System/MIDI L Ftsw
Cntlr and R Ftsw Cntlr parameters below).
