MIDI INTERFACE

Z-7

Operator´s Manual

Please, first read this manual carefully!

The MIDI INTERFACE enables you to execute MIDI switching operations and save switching
patches for amps/devices that are equipped with a MIDI INTERFACE PORT. It features
selective control via the 8 POLY channels or reception of all MIDI program changes from 01 to
100 via the OMNI mode.
Your ENGL device’s manual covers all MIDI-switchable functions in detail. This interface does not
require an external power supply; the amp/device provides the requisite current. Another
advantage of this device is that when it used in conjunction with the MIDI Footcontroller
Z- 12, the power for the footcontroller is routed from the MIDI Switcher via the MIDI cable. In
Practice this means the only cable you have to contend with is the MIDl cable to the footswitch!
The INTERFACE is easy to operate and handle, but nevertheless you should read this manual
carefully, especially the highlighted items. It contains a wealth of information you may need
later on if you have questions or encounter problems. Store it in a safe place for future
reference.
In order to simplify matters, from here on all references to an amp simply indicate any ENGL
product (combos, heads, 19" pre- and power amps) and interface denotes the ENGL MIDI
INTERFACE.

WRITE / EDIT

1 WRITE/EDIT

This key executes the following functions:
A) WRITE: This feature saves every changed setting of programmable switching functions when the
interface is in the MIDI mode. Once you have changed one or several setting(s) at the amp(s), only
those settings you just updated are saved and their previous settings deleted when you press the key
for approx. 1 second. The delay ensures you do not unintentionally delete or overwrite a setting.
The STATUS LED (2) flashes briefly to indicate that the new setting is saved.
B) EDIT: This feature saves the current setting of every programmable switching function when the
interface is in the EDIT mode. The EDIT mode is ideal for initial programming or complete
re-programming. The EDIT mode is activated after you select a MIDI program location (MIDI mode),
provided you did not change a setting of programmable switching functions at the amp(s) before you
press this key for approx. 1 second. In this mode all settings at the amp(s) are identical to the
settings of the respective pushbuttons. The current setting of every programmable switching function
is saved once you press the key again. The EDIT mode is active when the STATUS LED (2) and the amp’s
MIDI MODE LED illuminates continuously.

2 STATUS

This red LED indicates different modes and functions:
a) The LED flashes slowly three times after you power the device up. This is the internal system self-test.
The LED estinguishes to indicate normal operating status after the system has been proved.
b) The LED flashes rapidly after you switch the device on to indicate a system error. A possible source of
the fault is a defective EEprom.
c) The LED flashes rapidly after you have selected a MIDI program location: The MIDI program change
has been transmitted via a MIDI channel which is not selected on the Interface. In other words the
MIDI channel being sent from the MIDI device (e.g. a MIDI Footcontroller) is not in accordance with
the MIDI channel on the Interface and therefore the Interface does not change to this program
location. As soon as a new MIDI program change command is received via the selected MIDI channel,
the LED stops flashing and the Interface changes to the respective program location.
d) The LED flashes briefly after you have pressed the WRITE/EDIT key: The Interface saves a single or
several changes in the MIDI mode or all settings in the EDIT mode.
