SYSTEM EXCLUSIVE: enables the instrument for System Exclusive
operations (On).
When this parameter is set to Off, System Exclusive operations are excluded.
System Exclusive is the term that describes the interfacing of the WX instrument with
other devices (Sequencer, Host computer, etc.). System messages are not assigned to any
particular MIDI Channel. They are recognised by MIDI receivers regardless of the basic
channel to which they are sent. The messages are Hexadecimal codes and each
instrument’s System Exclusive messages have their own format according to an assigned
manufacturer’s ID number. System Exclusive sends data such as patch parameters,
sampler data, or a sequencer memory bulk dump. A format which is appropriate to the
particular type of transmitter is required.
A typical connection is a WX2 and a computer. In practice, System Exclusive can dump
an entire block of data at high speed; it can be used to transfer, for example, the entire
contents of a WX Bank/Song into a computer and so build a library of Songs.
Another common use of System Exclusive is to programme the instrument by accessing
the Edit environment through a computer which makes use of a program specifically
prepared for this task. This kind of work utilises System Exclusive as the means of
communication between the computer and the instrument.
MIDI CHANNEL LOCK: locks a MIDI channel configuration for
the instrument as a whole.
This function is valid for transmission and reception, fixing a Channel configuration for
all Performances (Real Time, Style and Song), overriding the individual MIDI channel
assignments for the instrument’s Performances.
In practice, MIDI CHANNEL LOCK provides the instrument with a means of commu-
nication with all connected units across a “standard” MIDI configuration (programmed
in the MIDI Channel page).
This function is particularly useful in cases that involve, for example, loading a song that
contains complex Performances which could alter your MIDI setup. For example, you
may be in concert and the Song you are about to load may have been produced in a Studio
by a setup consisting of 28 external expanders and a Midi mixer, all piloted by WX - the
result would be destructive to your programmed MIDI setup that may have taken hours
to perfect.
A MIDI Accordion communicating with WX would also require a locked MIDI Channel
configuration. For example, if the MIDI Accordion has to exploit the WX Styles,
program the Styles MIDI Configuration to the required setup then set MIDI LOCK to
ON. The MIDI configuration could be as follows:
WX Accordion
Drum (Track 1) = [Ch 10] OFF or Ch.10 N/A
Bass (Track 2) = Ch 3 Bass section = Ch 3
Accompaniment (Tracks 3 & 4) = Ch. 2 Chords section = Ch 2
Track 5 = Ch 2 Chords section = Ch 2
Track 6 = Ch 1 Treble section = Ch 1
Connecting with MIDI
Accordions
Some instruments may
have incorrect octave
transpositions when
connected to a MIDI
Accordion.
You can correct this
using one of two
solutions:
1. Transpose the
relative WX tracks (Edit
Performance -
Transpose function).
2. Transpose the
Accordion section
accordingly.
