There is none.
But I am currently working on one (with DMaker).
Bad thing is, I'm not a keyboard player. I play guitar, so I use my Rack mostly as a multi. I don't really know what a keyboard player needs as far as MACRO editing patches and all.
The driver is not full yet. I can get the program patches and combi patches, global and multi dumps. I've worked on a few mixermaps to control my multis and on a Macro Editor for the programs. But like I said, I'm no keyboard player.
E-mail me if you want the file I have so far and if you want anything special as far as Macro Editor controls tell me also. It will only help me see what needs to be worked on more...
