Midi Controls - Ecler nuo 4 Bedienungsanleitung

6. MIDI CONTROLS

The NUO4 is a DJ mixer that allows to control external devices using MIDI protocol. MIDI functions that are
assigned to each control are user programmable with Ecler Control 4 Lab software.
MIDI (Musical Instruments Digital Interface) is a standard communication protocol between electronic musical
instruments and computers. A MIDI device can operate as a slave (controlled) or master (controller). NUO4
operates as a master unit, which means that it is able to control other electronic musical instruments (synthesizers,
sequencers, rhythm machines, and software... even light controllers). Also, the NUO4 can receive MIDI messages
but only for programming with Ecler Control 4 Lab software.
MIDI OUT connection is done through a standard 5-pin DIN connector (180º). The mixer also incorporates a
USB-MIDI interface to send and receive MIDI information between the mixer and a computer through USB port.
NUO4's MIDI messages belong to 'Channel Messages' and 'System Messages' categories. Transmitting and
receiving devices must be set on the same channel for the message to be communicated.
The NUO4 sends three different types of MIDI messages:
•
Note-On and Note-Off messages
•
Control Change messages
•
System Real-Time Messages
6.1. Connections
There are two audio input connection modes for MIDI-controlled external devices:
•
Connecting the external device to any NUO4 H-LINE input.
•
Connecting the external device to NUO4 Input 5 (equipped with a gain control)
Device connection is especially important when using DJ software. For this reason, a soundcard with at least two
outputs is recommended.
There are two operating modes to use DJ software with NUO4:
•
Using the DJ software virtual mixer that is MIDI-controllable from channels 2 and 3 of the NUO4. In this
case, you would have two outputs on the sound card: one for the MASTER signal and another one for the
PFL signal, which connect respectively to INPUT 5's AUDIO IN and PFL of your mixer.
•
Without the software virtual mixer, therefore using channels 2 and 3 of the NUO4 in analog mode. In this
case, the two sound card's outputs are for the two virtual players and will be connected to any H-LINE
input.
6.2. Mixer channels with MIDI messages sending capabilities
Channels 2 and 3 of the NUO4, in addition to their analog operation with PHONO and H-LINE, allow to send MIDI
messages controlling external devices. In order to do that, you have to select the MIDI option with the input
selector. The main application is the control of similar functions (GAIN, EQ, FADER...) on a DJ software virtual
mixer.
