capture > create > control

Bome MIDI Translator Pro is a versatile MIDI mapping, processing, and scripting tool. Create custom MIDI routings, rules, logic, layers. And with keystroke and mouse emulation, you can control any software on your computer using a MIDI controller.

Some examples where Bome MIDI Translator Pro is used:

  • by musicians, both hobbyists and professionals
  • by DJs and controllerists
  • by lighting engineers
  • in music studios and TV studios
  • on big and small stages
  • in theaters
  • by photographers for raw development
  • for MIDI control of games
  • in research and development for rapid prototyping


Bome MIDI Translator Pro is a popular MIDI and keystroke mapping tool: use it for controlling arbitrary software by way of MIDI and keystrokes. Its rich feature set also allows it to be used for general computer automation.

With Bome MIDI Translator Pro you can control your computer from MIDI or other devices. For example: you can control your favorite software with a MIDI control surface, use MIDI turntables with arbitrary DJ software, map MIDI messages to other MIDI messages, and much more.

You can create your own mappings by defining the translations, or use one of the many pre-existing translation presets. We are constantly working on new presets, and the active community expands the available pool of presets, too.

At Ableton, we’ve found Bome MIDI Translator Pro to be super helpful for prototyping new hardware products. It was essential to our first ‘hacked’ prototypes of Push 1, where we chopped up a few MIDI controllers, and combined them with a movable set of buttons using Legos and a Livid Brain. More recently, we have used MT Pro along with Adobe XD, so we can trigger mockups with our actual hardware prototypes. MT Pro is extremely flexible for designing exactly what you want — for commercial or personal use — without needing to be a software developer.

MIDI Translator Pro works by specifying mappings for different input and output types. Below is a list of different trigger types (Incoming) and action types (Outgoing). You can combine them as you wish (e.g. do keystroke-to-MIDI conversion, or MIDI-to-mouse mapping).

Incoming Actions

  • MIDI messages
  • MIDI Port plugged in/unplugged
  • keystrokes
  • timer
  • application focus
  • enable/disable the current preset
  • opening a project file
  • bytes or text on a serial port

Processing ("Rules")

A sequence of rules can be defined to be processed if the incoming action matches:

  • assignments of variables, e.g. pp = 20
  • simple expressions, e.g. pp = og + 128
  • labels and goto, e.g. goto "2nd Options"
  • conditional execution, e.g. IF pp < 20 THEN do not execute Outgoing Action

Outgoing Actions

  • MIDI messages
  • MIDI port
  • add/remove/disable/enable MIDI routes
  • keystrokes
  • mouse movements
  • application focus
  • create/start/stop timer
  • change active preset
  • enable/disable the current preset
  • execute program
  • send bytes or text to serial ports
  • execute AppleScript (macOS only)
