If you are a Stick player who is not satisfied with your midi options, I recommend having a look at The Megatar. Already a custom built instrument designed around purity of tone and responsive feel, a Megatar set up with Stick tuning and hexaphonic midi output is the answer to a lot of questions that you did not even know you had.
While your at it why not throw in acoustiphonic piezo preamps and bartolini humbuckers. Can't you feel the power!?!
From Graphtech, the maker of the midi system that I use:
