Here are the two example files from the post above zipped together - “My MIDI Controller” to embed and the parent “My Very Much Improved MIDI Controller Rack”. Place them both in your racks folder and load the parent to see the entire setup with the embedded version of the “My MIDI Controller” rack, and load and alter “My MIDI Controller” to make one to embed in new parent racks.

The settings are generic enough that you could use these as a starting point to create your own setups. Should work for MPK225 with some pruning and with MPK249 and MPK261 as-is.
