Control the LVS-400 from an External
Device
You can connect the LVS-400 with a MIDI device, and control the LVS-400 remotely.
What is MIDI?
MIDI stands for “Musical Instrument Digital Interface” a worldwide standard that allows performance data and other
information to be exchanged among musical instruments. MIDI compatible devices can be connected together easily
using MIDI cables. Once connected, performance data can readily be communicated between the two devices; or one can
make settings for, as well as control the operation of the other device.
Normally, after power up (with V-LINK off), the LVS-400 outputs the corresponding MIDI messages from its MIDI OUT
when its buttons and knobs are operated.
Conversely, when any of the supported MIDI messages arrive at its MIDI IN, the LVS-400 performs the same functions
that it would if its buttons or knobs were operated.
* MIDI message values are in hexadecimal notation.
