IN-DEPTH FEATURES OVERVIEW (continued)
3.2 ADVANCED CONNECTIVITY AND
COMMUNICATION
The EM1 malletSTATION is a class-compliant MIDI device,
which means you can connect it to just about anything that
can accept MIDI information. Using the included USB cable you
can connect to a computer running any modern OS (MacOS,
Windows, iOS, Android, and Linux) that supports the class-
compliant USB MIDI standard.
3.2.1 The KMI MIDI Expander (optional)
The KMI MIDI Expander allows the malletSTATION to
communicate with traditional 5 pin MIDI hardware.
Using a mini USB cable, connect the mini USB port on the
malletSTATION marked 'KMI Expander' to the Expand port of
the MIDI Expander. Provide power using a USB power supply
into the Power USB B port on the Expander (most USB power
supplies provide 5V and plenty of amps, but be sure that the
power supply being used is rated for 5V and at least 500 mA).
No further configuration is needed, the MIDI Expander output
mirrors the MIDI data that is sent over USB. Simply connect
the MIDI Out of the Expander to the MIDI input of your
synthesizer/MIDI hardware. The MIDI out LED will light yellow
indicating that the Expander is passing MIDI data.
3.2.2 Preset Recall
There are 4 preset slots on the malletSTATION that can be
recalled either through buttons (Preset Select Mode, see
more information in the malletSTATION Editor section of
the manual), or through Program changes sent back to
the unit. Presets can be selected by sending a Program
Change message back to the malletSTATION from software
or hardware. Simply send a Program Change message 0-3
(0=Program 1, 1=Program 2, 2=Program 3, 3=Program 4) back
to the malletSTATION on MIDI Channel 10 to select one of the
4 onboard presets.
You can also connect to the optional MIDI Expander (using
the port marked 'KMI Expander') to communicate with MIDI
hardware using traditional 5 pin MIDI connections.
3.2.3 External LED control
The LEDs of the faders and buttons can be controlled remotely
by sending MIDI data back to the malletSTATION. All remote
messages should be on channel 10.
To light the LEDs on the faders as they would if you moved
your finger across them, send CC 30, 31, and 32, to control
the horizontal fader, the left vertical fader, and the right
vertical fader, respectively. You can address individual LEDs
of the faders by sending MIDI notes 0-11 for the horizontal
fader, 12-23 for the left vertical fader, and 24-35 for the right
vertical fader.
Control the preset button LEDs with notes 36-43.
Control the Octave button LEDs with notes 44-47.
Control the Low Note Button LEDs with notes 48-51.
Control the Low Note Indicator LEDs with notes 52-62.
