first question on the new Q&A section! In MIDI Translator Pro, you can do that in a simple way using the dedicated MIDI message:
In your translator’s Incoming section, chose MIDI, then Control Change as type.
Set the channel to the MIDI channel you want (your example uses Channel 13)
Then for the controller#, if you want it to be 37, enter 37 into the field. If, however, you want to react on different controller numbers, check “any controller#”, then select a variable (say ‘oo’) which will be set to the controller number of an incoming control change message.
The same applies to the controller value: most likely, you’ll want to map all controller values, so you’ll select “any controller value” and then assign it to a (different) variable (say, ‘pp’).
Now in the rules and in the outgoing section, you can use the variable oo and pp as you like. If you use global variables (e.g. g0-g9, ga-gz), then you can access them in other translators, too, containing the last controller# and controller value.
Let me know if that’s what you want to do.
