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:
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 Windows 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.

Trigger actions from incoming MIDI messages. Here, the MIDI port(s) are selected directly on which to receive the MIDI messages.
Select the MIDI message for incoming trigger/outgoing action by type. 14-bit controllers, (N)RPN messages, Pitch Bend... forget hex codes! (unless you like them: then use Raw MIDI).
Use MIDI Capture to pre-fill the MIDI actions with MIDI messages.
When the MIDI outgoing action is executed, a MIDI message is sent, which you specify here. New in v1.8: select MIDI messages by message and not by hex codes.
New in version 1.8.4: explicit support for receiving and sending MPE zone messages.
In the project properties and preset properties, you can select default MIDI ports to be used. You can also add/remove/edit MIDI port aliases.
Trigger actions by pressing keys on your QWERTY keyboard.
Use this outgoing action to emulate keystrokes of your QWERTY keyboard. For example, control other applications with shortcuts.
On Windows, you can inject keystrokes directly into some applications, even if they're not the currently active application.
Emulate typing text on your QWERTY keyboard (rather than only emulate keystrokes)
The new rules editor with a simple rule and the drop down list of the rules wizard.
An example of rather complicated rules.
Up to 9 virtual MIDI ports, optionally short port names.
With this outgoing action, programs can be started or documents be opened.
Execute AppleScripts directly from outgoing actions.
The MIDI Router to create MIDI Thru connections.
Use this action to start a project-internal timer to trigger incoming actions after a while and/or in regular intervals.
With this outgoing action, you can move the mouse, click mouse button(s), and move the wheel.
On Windows, inject mouse messages directly into certain applications, even if they're not currently in foreground
Use this action to enable or disable presets in the running project.
Trigger actions from received bytes or text on a serial port.
Send bytes or text to serial ports in response to a triggered incoming action.
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).
enable/disable the current preset
opening a project file
bytes or text on a serial port
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
