MIDI channel for sending foot controller data is selected and stored in the
routine.
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. The
function, in combination with the
and buttons. The
function (which is executed via the button
in
) switches between the initial (
depending on the selected characteristic curve) and the current value.
The four send intervals of 10, 20, 30 and 50 ms (milliseconds) determine the rate at
which digital controller values are sent to the
port. In technical terms, the
selected interval defines the time between individual send controller data. The
will respond slower at higher interval settings and
the control operation will be performed faster at a shorter interval. The lower the
value selected, the faster the data transmission rate. While manipulating an
external Expression Pedal a short interval will result a high amount of transmitted
data.
This term describes a passive electrical circuit in the foot controller that is opened
and closed by a relay. Two of these
are assigned to each stereo jack,
whereby both share the jack's ground terminal. The second terminal of the two
is assigned to the jack's stereo or mono contact. Taking the place of
conventional two-way footswitches with on/off functionality, the four
serve to remote control functions of amps such as the ENGL Screamer, ENGL Ritchie
Blackmore Head, ENGL Powerball Head and many more. You'll find the
terminal assignments and circuit diagrams on page 23.

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?
