Can do MIDI to MIDI filtering with MT?

a user asked:

With the midi translator for osx, can you translate specific incoming messages to other midi messages, or is it just keystroke outputs?

also. if i was to want to translate some incoming messages from a keyboard that i use with ableton live, how would the flow of messages need to go?

would the midi translator show as an available midi input and output in ableton or would it just work without having to flow the signal around?

Hi,

yes, this is certainly all possible. In fact, MIDI to MIDI conversion is the core strength of Midi Translator!

Indeed, MT installs a virtual MIDI port that you can select as MIDI IN in ableton live. So your "flow" would be:

MIDI Keyboard -> MT -> Ableton

For that, do the following:
in Ableton:
- select "Midi Translator Virtual" as MIDI IN
- unselect the MIDI keyboard

in MT:
- select Keyboard as MIDI IN (was previously selected in Ableton Live)
- select "Midi Translator Virtual" as MIDI OUT
- select MIDI Thru in the options menu so that by default, all messages from the MIDI keyboard are passed thru to Ableton

Now you can filter MIDI messages in MT, e.g. a translator to transpose all notes by one semitone:

INCOMING: MIDI 90 pp qq
check "swallow"
RULES: pp = pp + 1
OUTGOING: MIDI 90 pp qq
