Frst timer hope it works.... Any corrections, suggestions etc welcome.

Ok just a brief description for now. This was made to help me hear a chord spelling in any key quickly. Partly for chord ear training, part Music Theory curiosity.
So I mapped this layout to iGrandPianos's transpose dial (+/-12) using midiCC 25.

The intervals on the right are mapped and relative to the key C4.
The 25 notes (C3-C5) are mapped to a transpose dial of (+/12) using midi CC25. All intervals on the right become relative to the new transposed key chosen.
The intervals bottom left are also relative to current key, mapped 2 Octaves below the root.
There is a tiny knobl currently hidden from view bottom center. This can be made visible via design mode and can be used as the target of midi learn for iGrand's transpose dial.
Posting this now and will add more detail tomorrow.
Big Thanks to Dan, who helped with the questions I had the last few days.
Cheers. :)
