Ecler NUO4 Mode D'emploi page 16

ATTENTION: With Windows® XP, if you connect the NUO4 to different USB ports on your computer, you'll have to
repeat the installation for each port and to restart your equipment each time. On the contrary, if you use
Windows® 2000 and connects the NUO4 to different USB ports on your computer, you won't have to repeat the
installation for each one of them, the system automatically identifies them.
We recommend visiting Ecler's web page (www.eclerdjdivision.com) in order to check if driver or software updates
are available.
7.1.3. NUO4 driver uninstall
In order to uninstall NUO4 drivers from any operating system, disconnect first NUO4 USB cable from the computer.
Run 'uninstall.exe' program from the 'Driver' folder on the CD.
1. Follow the wizard instructions.
2. Once the process completed, NUO4 USB-MIDI drivers are uninstalled from your operating system.
This utility uninstalls drivers for all ports on the same computer.
7.2. Controls programming
A same MIDI control can be configured to send different types of message depending on the specific needs of the
external device the user has to control. Programming is done from Ecler Control 4 Lab software.
7.2.1. Rotary controls
The different messages MIDI rotary controls can send are:
•
Incremental control: it sends a control change message with the value increase to be done on the related
control; if it is rotated to the right, increments are sent (value 1 to 4) and if it is rotated to the left,
decrements are sent (value -1 to -4). This type of message is well suited for NUO4 MIDI rotary controls 1A
to 1D when you want to manipulate rotary or sliding controls, since they correctly operate independently of
the absolute position they have.
•
Absolute control: it sends a control change message with the current absolute value the related control
must have. The value range is 0 (completely to the left) to 127 (completely to the right). The rotary and
sliding controls of NUO4 channels 2 and 3 only accept this mode. Although this mode is not so useful with
NUO4's MIDI controls 1A to 1D, it has been implemented for compatibility.
•
Two unlatch buttons: turning to the right sends a Note-On/Off message and turning to the left sends a
different one. This type of message is well suited when you want to control a pair (like up/down, +/-...) with
a rotary button.
•
Any NUO4 MIDI control 1A to 1D can be used to finely adjust the tempo (BPM). In this mode no MIDI
command is sent.
