controller number 8, and selecting a descending logarithmic curve and a 50-ms
send interval:
-> Press
four times; the display reads >00.7.<, >00.6.<, >00.5.<, >00.4.<
-> Press to select the controller curve characteristic, in this case a logarithmic
descending wave form; display reads >l.o.< and a special symbol at the right
position signifying an descending curve.
-> Press to set the controller command send interval to 50 ms.
-> Press to store the changes; the display confirms the programming
process by indicating >Pr.o.<.
Once the settings have been stored, the Z-15 quits the
routine
and returns to

Note: The system will quit the
routine automatically after about
20 seconds.
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
configuration:
Controller number -> 7 (for volume controllers like those featured on the E580
Preamp). This number determines the MIDI device function that you want to
manipulateusingthecontinuouscontroller.Tolearnmoreaboutthevariousfunctions
and their controller numbers, consult the manual of the device whose 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,youcanincreasethesendinterval(to30or50ms)toelicitaslowerresponse

on the selected curve characteristic. You'll find this option quite useful in the real
world, particularly if you do not own an external expression pedal or want to use the
as a second expression pedal. In addition to its
standard control function, button lets you switch between the initial value of the
selected curve (0 or 127) and the controller value most recently selected with button
