an EQ bank button lights the associated
LED, and the last selected EQ band for
each of the four banks is remembered.
To describe the MIDI controller numbers
used for the EQ knobs, we will number
the EQ bands from bottom to top; LO=0,
LO MID=1, HI MID=2, HI=3. “E”
represents the currently-active EQ
band/LED:
GAIN knob
sends
MIDI controller (18 + 3*E + 32*B)
FREQ knob
sends
MIDI controller (17 + 3*E + 32*B)
Q knob
sends
MIDI controller (16 + 3*E + 32*B)
The values sent follow the same rules
as described for the PAN knob,
including coarse and fine control with
the SET button.
Data Wheel
The DATA wheel will also send 4
different MIDI controller number
messages in each of the four banks.
The controller number sent depends on
whether the ASN, F1, F2 or F3 LED is
lit.
If we label the currently-lit LED as"F",
and number the buttons as ASN=0;
F1=1; F2=2; and F3=3, then the DATA
wheel sends MIDI controller number:
DATA Wheel
sends
MIDI controller (28 + F + 32*B)
Again, the same rules apply as with the
PAN and EQ knobs, including the
coarse and fine increment modes as
modified by the SET button.
Global Controls
Some of the US-428 controls have the
same behavior in all four banks. These
include the MASTER fader, LOCATE
buttons, and transport buttons. All of
these global controls are transmitted on
MIDI channel 2 of the US-428 control
port (as opposed to all the bank-related
controls, which transmit on channel 1 of
the control port).

Controlling LED’s
Some LED's may be controlled by the
application. LED's are turned on with a
Note On message with a velocity of 127,
and turned off with a Note On message
with a velocity of 0. Four banks of MUTE
and REC LED's can be controlled by
sending messages to channel 1 of the
Control port. Transport LED's can be
controlled by sending messages to
channel 2.
