You can't use it without a MIDI mapper, though, because while I've rearranged the physical keys, that doesn't make it send different MIDI signals. I was trying to help someone get set up with one, and it turns out that the state of MIDI mappers for non-programmers isn't that great. Plus, with 98 keys, that's a lot of data entry. So I've made a stand-alone version for Mac: source code, executable program.
It's a quick cut-down version of the code behind my rhythm stage setup that looks for
an Axis-49 and presents a virtual MIDI device (
jammer) that produces
the mapped notes. There are two binaries, one for holding the device
with (non-functional) transpose keys up, the other with transpose keys
If you sometimes play with sharp-key instruments and other times play with flat key ones, you can turn the device over and use the other binary, with a transposition MIDI mapper. This lets you have a range from F to B (F, C, G, D, A, E, B) in one orientation, centered on the key of D, and Db to G (Db, Ab, Eb, Bb, F, C, G) in the other, centered on the key of Bb, in the other.
 Three good ones, and one that's too old to go into "selfless" mode and so is effectively only half a keyboard.
