This unassuming little box is several products in one. It is a MIDI fader
box, with four physical faders (eight virtual ones) and four buttons
which can generate a variety of MIDI messages including system exclusive.
It contains patch storage and editing
modules for a variety of Lexicon products, including
. It can drive multiple
modules (up to sixteen). It can function as
a MIDI patchbay/processor, routing and filtering data in various ways from
its two MIDI inputs to two outputs. It can multitask several MIDI patches,
which can generate and feed data among themselves. It has an onboard
MIDI monitor for its two inputs. And it takes two
The MRC is pretty essential for owners of the LXP-1 and LXP-5 who wish to
program their own sounds. It is also extremely useful for general MIDI
processing. The faders are solid, and do not glitch. The buttons (rubber
membrane) seem to be properly debounced as well. I have had very few
problems with it: a faulty LCD display was replaced last year, and the
only software problem (incorrect display of some numerical values) occurred
in 1991 and I've never managed to reproduce it.
I strongly recommend this box to anyone seriously involved with MIDI,
even at inflated UK prices. My only minor criticism is that the rear
panel components (specifically, the MIDI ports) are PCB-mounted and
might develop problems with the continual plugging and unplugging
associated with live work. Also, my usual warnings about software bloat
and maintenance apply: my unit is quite old and runs an obsolete software
version. I have no idea how the latest versions compare in terms of
reliability, or whether they still support editors for older devices.
