  • Ready-to-use with most drum kits - comes pre-programmed with MIDI note mappings which work with most popular drum kits. (You can easily customize the note mappings if needed).
  • Integrated PlayStation® (2 or 3), or Wii® game controller with navigation "joystick", Start, Select, and Back buttons. Everything you need to control your PlayStation or Wii and navigate menus. Plugs into a USB port with the supplied cable.
  • Adjustable MIDI note velocity threshold so light taps or crosstalk can be ignored.
  • MIDI notes can be mapped to each note "channel" any way you wish. Several MIDI notes can be mapped to each game "channel" (or note color). For example, you can map both the rim and pad notes to same channel.
  • Two independent note maps are available. You can have different mappings for different songs, or one set of maps for Rock Band, another for Guitar Hero. You can quickly switch between maps, even "on the fly".
  • Includes Windows software to easily view and edit note maps, log and examine MIDI data, test your settings and diagnose problems. Save and recall settings. (Use of software is optional -- the MIDI Rocker LX can be completely programmed using the front panel controls).
  • MIDI OUT option for connecting to MIDI input on GHWT drum controller (for Wii or Xbox). Automatically converts MIDI data into values required to work with the GHWT controller and filters out data which causes "double-hit" issue on the Wii. No modifications are required to the GHWT controller.
  • Free firmware updates. Flash memory for firmware upgrades to add new features and compatibility with new games and devices. (A Windows PC is required to install firmware updates).
Game/Console Options:
  • MIDI Rocker LX connects directly to the USB port on the console.
  • Emulates both the Rock Band 2 controller and the Guitar Hero World Tour controller.

  MIDI OUT Option  
  MIDI Rocker LX with MIDI Out Option
MIDI OUT Option installed in MIDI Rocker LX.
With the MIDI OUT option, you can connect the MIDI output of the MIDI Rocker LX to the MIDI input on a Guitar Hero World Tour (GHWT) drum controller and the MIDI Rocker LX will automatically convert the MIDI data received from your drum kit into the values required by the GHWT controller. You can take advantage of all the features of the MIDI Rocker LX like flexible note mapping, crosstalk rejection and multiple note maps.

The Guitar Hero World Tour (GHWT) drum controller has MIDI input which accepts MIDI data and works with some drum kits. Unfortunately it requires specific MIDI note numbers, and if your drum kit's brain doesn't allow you to assign specific note numbers to each trigger input, it may not work. Even if your drum brain has this capability, it can be difficult and time-consuming to set up the proper configuration.

There is also a known "double-hit" problem with using Roland drums with the GHWT controller on the Wii -- the MIDI OUT option has been specially designed to fix this problem.

Price: $15*

*Note: The MIDI OUT Option is valid only when ordered with a MIDI Rocker LX. If you already have a MIDI Rocker LX and are interested in adding the MIDI OUT Option, please contact me at for more information.

Have enough MIDI cables? To use the MIDI OUT option, you will need 2 MIDI cables -- one to connect your drums to the MIDI Rocker, another to connect the MIDI Rocker to the GHWT drum controller.
