Diatonic Environment?

[dr]

Many years ago I downloaded a couple of environment layers which were pretty cool (I cant remember from where). I remember Diatonic and Pentatonic, but I can only find the Diatonic layer from a very old logic project file of mine. I couldn't find any references to it here on this forum or elsewhere online. I remember it worked similar to a chord memorizer in that it would re-voice what you played on the keyboard. It's been a while since I've delved into the environments and I cannot remember how to use this though because the inputs and outputs aren't that clearly labeled to me and it was originally setup for old serial midi interfaces. Does anyone know?

I have also attached the file.
