Controls and Connectors
Front Panel
1. Buttons 1 through 5 – These buttons select the active preset number within the current bank. Pressing one of
these buttons will immediately call up the selected preset. The LEDs above these buttons shows which preset is
currently active.
2. Bank Down and Bank Up – These buttons select the bank you wish to select presets from. When either of these
buttons is pressed, the preset number and preset LEDs begin flashing. Pressing Bank Down decreases the current bank
number by 1 (down to a minimum of 0) and pressing Bank Up increases the current bank number by 1 (up to a
maximum of 24). Once you’ve reached the desired bank, press one of the preset (1-5) buttons to select a preset within
that bank. The MasterMind doesn’t send any commands until a preset button is selected.
3. Function button – This button can be used to send Continuous Controller messages, or it can be used to access the
Alternate Preset function found on other RJM Music Technology products. It can be configured differently for each
preset. The Function button is also used to activate or deactivate Instant Access mode if Instant Access mode is
enabled.
4. Display - The display shows the current bank and preset number. It will show a three digit number such as “123”,
where “12” is the current bank number and “3” is the current preset within that bank. If the Alternate Preset feature is in
use, the display will show an “A” before the bank number.

6. Power – The MasterMind can accept power supplies of 9 to 18 volts, AC or DC. The power supply must be able to
deliver at least 200mA. The connector is a standard 5.5mm/2.1mm barrel connector and can be either center negative
or center positive.
7. Exp Pedal – This jack allows you to connect an expression pedal to the MasterMind.
8. Remote In – This is a MIDI input port. It can be used for receiving MIDI patch data, program changes or can be used
to connect multiple MasterMinds together and allow them to control each other.
9. MIDI Out – This is the main MIDI output. Connect this port to the MIDI device(s) you wish to control. You can use a
standard 5-pin MIDI cable here, but if you connect a 7-pin MIDI cable, you can phantom power the MasterMind over the
MIDI cable. If you phantom power, you can use the MasterMind without it needing its own power supply.
IMPORTANT NOTES ON PHANTOM POWER: Don’t connect a power supply to the MasterMind if you are phantom
powering it! Doing so can damage the MasterMind and/or connected devices! Also, before attempting to phantom
power the MasterMind, please make sure the device you’re connecting to is compatible. The device must provide 9 to
18 volts AC or DC over pins 6 and 7 of the MIDI cable. All RJM Music Technology products are compatible, as are many
others such as those by Rocktron. Products that provide phantom power over pins 1 and 3 of the MIDI cable (such as
the Voodoo Lab GCX) can not phantom power the MasterMind without the use of a special 5-pin to 7-pin adaptor.
Connecting such a product directly to the MasterMind can damage the MasterMind. Please visit the FAQ section of the
RJM Music website for a list of products known to be able to phantom power the MasterMind.
