Congratulations on your choice! With theZ-15 MIDI Foot Controller, you now
own anextremely robust and very versatile MIDI foot controller housed in a fetching
stainlesssteelchassis.
3. offers two inputs that accept two expression pedals, equipped with
potentiometers.
4. enables controller numbers to be assigned freely to each expression pedal.
5. allows four different control curves to be assigned to every continuous controller.
6. offers a variable transmission rate (send interval) for controller words to affect
the response of the remote controlled function.
7. features four Switch Loops. Statuses (open/closed) may stored for each
of the 128 MIDI patches. This convenient feature allows four switching
functions for external devices to be executed simultaneously at the
touch of a single button on the Z-15.
8. selects MIDI patches in groups of ten patches called banks or directly,
with the latter requiring confirmation.
9. offers a special feature - button-operated Internal Continuous Controllers.
10. A very practical power supply option: via a 5-pin MIDI cord connected to
ENGL amps, power amps or preamps equipped with a MIDI IN port featuring
phantom power that is enabled via the "ENGL MIDI Foot Controller" switch.
An outboard power unit is not required for this type of configuration.

Among the hallmarks of this Footpedal are painstaking workmanship and finishing as
well as rigorously tested and carefully selected quality components. You'll find
guidelines on care and maintenance on page 17. Under the heading Tips from the
designer,you'llcome across practicaltipsonthe aforementioned featuresthroughout
themanual.Allcriticalinformation concerning the operation of this Footswitch board
is preceded by "NOTE", "CAUTION", "Read and heed" or some other eye-catching
comment.We'recallingyourattentiontotheseremarksforreasonsofsafetyorother
compellingmotives,sopleasegivethemdueconsideration.
A few words of wisdom from the designer:
handling the foot controller is complicated, particularly if you work with expression
pedals and want to define their parameters. To nip frustration in the bud, I suggest
you follow along with the examples on pages 12 to 17. This will give you a better
understanding of and hands-on experience with the foot controller's functionality. In
no time at all, you'll discover that it actually handles very comfortably and
conveniently.
In this section, we'll first look at the two operating modes and setup routines.
Please refer also to the condensed instructions printed on the control panel.
For purposes of clarity, buttons and their functions are shown inletters,
while readouts appearing in the display are bracketed by the symbols >...<.

A tip from the designer:
The Z-15 gives you a wide range of options for fine-tuning a MIDI device's various
continuous controller functions. Let's look at an example of a frequently used
continuouscontroller
Controller number -> 7 (for volume controllers like those featured on the E580
Preamp). This number determines the MIDI device function that you want to
manipulateusing thecontinuouscontroller. Tolearn moreaboutthe variousfunctions
andtheircontroller numbers, consult the manual ofthedevicewhose parameters you
wanttomodulate.
Set the controller curve to positive linear or log. positive, depending on the employed
pedal and the desired effect on the control operation. Set the controller value send
interval to 20 ms or a bit longer if you prefer a different response. When determining
the send interval, ensure the device at the receiving end of controller data is able to
handle the selected rate of incoming data. If the send interval is too short and a pedal
control operation sends tremendous amounts of data, the receiving device may well
ignore some controller values. In other words, it may not respond correct to your
commands. For example, to manipulate the master knob on the MIDI Preamp 580
using an expression controller, set the send interval to 20 ms. For the internal
controller,you canincrease thesend interval(to 30or 50ms) toelicitaslowerresponse

In this manual, MIDI programs are called MPNs (MIDI program numbers) as well as
MIDI patches. The terms are used interchangeably.
Though the MIDI standard defines program numbers 000 to 127 (0hex to 7Fhex),
almost all MIDI devices including this foot controller - indicate these programs
using a 1-to-128 numbering scheme.
MIDI channel:
The MIDI standard defines 16 channels for sending and receiving MIDI data. The
17
MIDI channel for sending foot controller data is selected and stored in the
Channel Setup
ContinuousController:
This is a control mechanism that addresses MIDI devices via the MIDI data circuit.
The connected devices must be able to respond to such commands, for example, a
volume change message sent via controller 7 using values ranging from.
Every (continuous) controller is assigned a controller number to which it responds
accordingly when it receives incoming controller values.
The ENGL Z-15 MIDI foot controller offers three control options using MIDI
controller data: 1.for connecting an external expression
pedal (a foot pedal with an analog resistor); 2.for
connecting a second external expression pedal (a foot pedal with an analog
resistor); 3. Thefunction, in combination with the

The four send intervals of 10, 20, 30 and 50 ms (milliseconds) determine the rate at
which digital controller values are sent to theport. In technical terms, the
selected interval defines the time between individual send controller data. The

Troubleshooting
The ENGL banner does not cycle through the foot controller's display after
plugging in the mains or MIDI cord.
-> When powering the Z-15 via an external power unit: Does the external
power unit supply the required current and voltage? (refer to
Technical Data on page 21).
-> Is the external power unit or cord defective?
-> Is there a loose connection in the cord's plug?
18
Does the plug fit snugly in the foot controller's socket?
-> When powering the Z-15 via the MIDI cord: Is your
MIDI cord equipped with the required 5-pin connector?
-> Is the MIDI cord defective (say, a short circuit or broken wire)?
Does it have the correct pin assignments?
-> Is the power supply selector (phantom power) for the
ENGL foot controller set properly on the ENGL amp (that is, to the

The connected amp or effect device fails to respond to MIDI program change
commands when you select an MPN on the Z-15.
-> Is the MIDI cord defective (say, a short circuit or broken wire)?
Does it have the correct pin assignments?
-> Check cable connections: Is the foot controller'sconnected to

theon the ENGL amp or MIDI device?
-> Are the Z-15 Foot Controller and the amp (or effect device) set to
the same MIDI channel?
To check this, you can set the amp (or effect device) to OMNI
Receive mode. In this mode, MIDI data received via all 16 channels are accepted.
Check the foot controller's MIDI send channel setting in the
MIDI Channel Setup
-> Is the connected MIDI device able to switch to the selected MIDI patch?
The number of MIDI patches on the MIDI device may be limited
(look this up in the MIDI device's operating manual).
-> Is your ENGL amp or ENGL MIDI peripheral device equipped with a display
providing visual confirmation?
If not (as is the case with the E670, E570 and Z-7), perhaps you have not
programmed different settings (presets) to the MIDI patches. This may explain
why there is no response when you select presets. Program presets with
different settings and try again.

position)?
MIDI Out
The amp addressed by the Z-15 or effect device does not respond to MIDI
controller commands when you manipulate an external expression pedal or the
Internal Continuous Controller.
Check the following items if the Z-15 foot controller's display does not respond to
the expression pedal (that is, it fails to indicate controller values):
-> Is the external expression pedal or its cord or plug defective?
-> Are the external expression pedal's terminal assignments consistent with the
terminal assignments of the input jacks for the two
on the foot controller? You'll find the assignments for the two jacks on page 23.
-> Did you plug the external expression pedal's connector into one of the two
jacks labeledor?
Check if you have connected the pedal to the appropriate port.
Try using the foot controller'sto carry out the given
function. If it too fails, you can rule out the aforementioned causes.
Check these items if the internal controller continuous also fails to elicit a response

from the amp or MIDI device:
-> Is the MIDI cord defective (say, a short circuit or broken wire)?
Does it have the correct pin assignments?
-> Check cable connections: Is the foot controller'sconnected

-> Are the Z-15 foot controller and the amp (or effect device) set to the same
MIDI channel? To check this, you can set the amp (or effect device) to OMNI
receive mode. In this mode, MIDI data received via all 16 channels are accepted.
Check the foot controller's MIDI send channel setting in the
routine and, if necessary, set it to the correct channel. Like program change
commands, controller commands are sent with a channel number.
-> Is the controller number setting on the foot controller consistent with the
controller number of the function that you want to remote control at the amp
or effect device? Example: On the E580 Preamp, controller number 7 has a
fixed assignment to master volume. If you use a
on the ENGL Z-15 to address this function, you must assign controller number 7
to it in the appropriateroutine.
-> Is the given controller function enabled at the amp or effect device?
Consult the amp or effect device's manual to learn how to enable or activate
the controller.
