Hi, I’m trying to use MTP to change the layout of my MIDI keyboard. It’s an Axis-49 isomorphic keyboard that I want to change from a chromatic layout to one that uses the Wicki-Hayden scheme. The advice in the old forum says to favor rules over translations–and I would definitely prefer not to reassign 98 keys by pointing-and-clicking–but I can’t figure out how this is done. I’ve been able to remap my keyboard in Midi-Ox by modifying an example text file, but I don’t see any such example files for MTP (if indeed they’re even possible, given that the file format is proprietary). The syntax of the rules is obscure to me–it took me a long time just to understand that the letter combinations are variable names–and I can’t figure out how to accomplish what I imagine is a very simple operation. (Is there any “cookbook” of common MTP tasks?) Thanks for any help.

If you cannot get to a know pattern, formula, you could do something like this Input Note on any note any velocity on channel X. Set pp to note, qq to velocity Rule if pp==1 then rr=1 if pp==2 then rr=7 if pp==3 then rr=3 … Output Note On value rr velocity qq on channel x The only thing I’m not sure of is performance of doing all in a single translator. If it doesn’t perform well, you could break this up into separate translators and perhaps each one only handle a portion of the incoming notes. You would need to put something to skip outgoing action if the incoming note is note within the range for the given translator, otherwise you would get duplicate note output.

If you provide me something that shows some sort of mathematical pattern on what you want to translate note from and to, perhaps I can help. Most of this would likely be a math exercise which means it can probably be done in just a few translators.
