Display of MIDI Parameter
Changes
In normal operating mode, when param-
eter changes are received via MIDI for any of
the front panel parameters (DECAY, DE-
LAY, or FX LVL), the appropriate LED will
light and the new value is briefly displayed.
When the display returns to the current effect
ID, the LED of the parameter just altered
remains on. Incoming MIDI data for patched
parameters which are not available from the
front panel is indicated by the flashing of all
3 front panel parameter LEDs.
In Advanced Programming Mode, the
uppermost parameter LED flashes to indi-
cate MIDI activity. MIDI parameter values
are only displayed if the parameter being
controlled via MIDI is the one already se-
lected by the REGISTER/PRESET knob.
When a parameter is controlled by a
patch, the value that is statically displayed
represents the effective value derived from
the stored parameter value and the offset
added by the patch. The stored parameter
value is the base value set for the patch. Turn
VALUE to briefly display this base value. The
effective parameter value will reappear auto-
matically after approximately 3 seconds.
Special Notes on MIDI
Programming
Reflex is designed to be compatible with
existing editing software, as well as with the
Lexicon MRC which recognize Reflex as a
Lexicon LXP-1. Due to differing parameter
ranges between the two effects processors,
scaling values are only approximate. In most
cases, the discrepancies encountered are
negligible.
One parameter, however, requires spe-
cial note. Reflex parameter 2 (Group Delay)
in the Chorus algorithm (A8), has a range of
0-1500ms, represented on the display by
values 1-120. To the MRC, this parameter is
recognized as LXP-1 parameter "Delay 1"
which has a maximum value of 800ms. In
order to access the entire Reflex range of this
parameter via the MRC, you must adjust the
parameter from the Reflex front panel, or
create a patch and use a controller. On
Reflex, set patch scaling as follows:
41
Reflex
scale value
+188 100% of range (1-120)
+94 50% of range (1-60)
-186 -100% of range (120-1)
-93 -50% of range (60-1)
In addition, the Delays and Feedback are
arranged differently in Reflex and the LXP-1.
Although we consider the Chorus algorithm
to be an improvement of the Delay 1 algo-
rithm in the LXP-1, the changes made do
cause areas of incompatibility between ef-
fects created on the two units. Registers
created from these algorithms, when loaded
into Reflex via an editor, will sound different
from one another.
If using an MRC, note that FDBK 3 on the
MRC is the feedback control for Delay 1 on
Reflex.
