Grid Tonnetz

If you use the Reason DAW with a grid controller and Grid64P0 from Retouch Control, you may be interested in this Tonnetz-inspired isomorphic layout Grid64P0 patch in which all chord types keep a consistent shape whatever their root note is. Also includes a tutorial manual and two printable graphic files: one shows the notes layout on the controller and numerous chord shapes; the other is a blank grid that can be used to draw chord progressions for composition or analysis purposes.
