1 item left

The MasterMind is the ideal companion to the Effect Gizmo, Rack Gizmo and Amp Gizmo. It is designed to work flawlessly with RJM products and will also control other standard MIDI equipment. With the MasterMind, you’ll have full control of your entire rig with the tap of a button!

  • “Plug and play” operation with RJM Music products
  • Can control any number of RJM products at the same time
  • Works with all standard MIDI devices
  • Can control devices on four MIDI channels at once (even more when using Continuous Controller
  • “Instant Access Mode” allows you to control both presets and individual
    loops on the RG-16 or Effect Gizmo
  • “Alternate Preset Mode” doubles the number of presets you have access to
    (when used with other RJM products)
  • Two or more MasterMinds can be used together and synchronized. Have controllers in different stage locations, or have one on the stage and one with a tech.
  • Power requirements: 2.1 mm 9-18 V DC or AC. 200 mA. Phantom power capable: the MasterMind only needs a single cable to carry both power and data when connected to another RJM Music product (or other phantom power capable product).
  • Phantom power: Accepted over pins 6 and 7 of the MIDI out jack, same specs as above. Phantom power is passed over pins 6 and 7 of the Remote In jack, current limited to 500 mA. Do not connect phantom power at the same time as the AC adaptor! Do not use pins 1 and 3 for phantom power!
