8. MIDI CONTROLLERS
8.1. Description
The EVO4 allows you to control external devices with the MIDI protocol. The functions of each MIDI controller are
set, and you must adapt your software or favourite external device to them.
MIDI (Musical Instruments Digital Interface) is a standard communications protocol used for electronic musical
instrument-to-computer connections. MIDI devices may act as a master (controller) or slave (controlled) devices.
The EVO4 works as a master unit to control other electronic musical instruments (synthesizers, sequencers,
rhythm boxes, software and even light controllers). The EVO4’s MIDI messages belong to the “Channel Messages”
and “System Messages” class. It is important for the devices that emit and receive these messages to use the
same channel, so that they can communicate with each other.
The MIDI OUT connector (49) sends all MIDI data generated by the EVO4 and is used to control devices with a
DIN5 connection. It also permits the transfer of the EVO4’s MIDI CLOCK signal, if this option has been enabled.
The mixer includes a USB-MIDI interface that allows you to send MIDI signals from the mixer to a computer via
USB.
8.2. MIDI controllers
The EVO4 includes 29 controllers that can send MIDI data:
16 potentiometers
4 buttons
4 dedicated encoder knobs/push-buttons
4 60 mm faders
1 45 mm crossfader
The controllers for channels 1, 2, 3 and 4 may operate independently as AUDIO controllers, if PHONO or LINE is
selected on the source selector, or as MIDI controllers, if MIDI is selected on the source selector. Each channel has
a blue LED (15) that lights up when it is operating in MIDI mode.
When a channel is operating in MIDI mode, the signal in its LINE input is sent to MIX. The VU and OVL work
normally, and the channel’s GAIN, PFL and FADER controllers double up their functions, sending MIDI data and
controlling the audio at the same time. As a result, you can adjust the input level (GAIN), listen to the signal in
advance (PFL) and adjust the level of output to MIX (FADER).
The EVO4’s crossfader always operates simultaneously in AUDIO and MIDI mode, regardless of the configuration
of the channels.
The top part of the mixer there is a MIDI CONTROL area with four encoder knobs/push-buttons. These encoders
always send MIDI data.
