B. Using the Lexicon MRC to Edit Realtime MIDI Settings
Most of the 601's internal parameters may be modified remotely using MIDI. In addition, many
parameters may be modified dynamically, while the 601 is passing signal (as if there was a
front panel knob(s) for the parameter(s)). The Lexicon MRC (MIDI Remote Controller) can be
used to edit the internal dynamic midi settings in the 601 by following these steps. Although
this chapter is devoted to the MRC and its use with the 601, there are other MIDI controllers
available that can perform comparably. This procedure was developed on an MRC having
software revision 3.01.
This procedure uses machine 15, MIDI port 1, setup 9 to control the delay block and setup 10
to control the real-time MIDI block. The following table lists the steps needed to program the
MRC to accomplish this. We assume that you already own a MRC and are somewhat familiar
with how it works. The table is divided into steps and each step has four parts: MRC Key, MRC
Display, Data to Set/Enter, and Comments.
❒
MRC Key represents a key on the MRC that you must press.
❒
MRC Display represents the display on the MRC. In some cases, this represents a portion
of the MRC display (for instance, a label for one of the sliders).
❒
Data to Set/Enter represents data that you must enter into the MRC via the sliders,
buttons, or keypad.
❒
Comments are just that: comments.
The following 9 steps exactly parallel the first 9 steps of the table. Refer also to the edit buffer
parameter tables in Appendix C. Read the notes presented after the procedure. They explain
some of the details behind the steps. This should help if you're trying to translate the procedure
to a different MIDI controller.
Step
What to do
1
Press the MACH key on the MRC. The display reads "MACH # ..." Press 15 on
the keypad, or use slider 1 to set the machine number to 15.
2
Press the ENTER key on the MRC
3
Press the SETUP key on the MRC. The display reads "SOURCE DEST ..." Press
1 on the keypad, or use slider 1 to ensure that the current setup is 10.
4
Press the ENTER key on the MRC.
5
Press the EDIT key on the MRC.
6
Adjust the slider under the "SOURCE" prompt on the display so that the
source is "slr1."
7
Adjust the slider under the "DEST" prompt so that the DEST is "SYSEX."
8
Adjust the slider under the "OUT#" prompt so that the OUT# is 1.
9
Press the PAGE key.
Note
: The length of this example may, at first, make the whole thing seem daunting or
extremely complicated. It is not. A vast majority of the process is highly repetitive and once you
have programmed two or three sliders, the pattern should begin to emerge and you can begin
working from memory.
Note
: Whenever one of the realtime blocks has been set up and attached to a parameter, trying
to edit that same parameter from the front panel results in the message
rEAL
, whenever the
Wheel is turned. This is true only for realtime blocks one and two, and not the
SEt
function
under realtime MIDI edit.
