I am getting a KORG M3 to complement my live gear, mainly to use it as a solo/lead synth. For that purpose 49 keys would be sufficient instead of 61 that M3 comes with.
Considering that M3 is already modular, with its core functionality placed in the module, would it be feasible to cut off the upper octave and create a 49-key version of M3. The mechanical side wouldn't be a problem, as I was thinking of bringing it to a machine shop to do it, but my concern is about the integrity of circuit board to which the keys attach to. Cutting portion of the board might lead to loss of all the remaining keys.
I am sure this is not a radical idea, so I guess some of you thought and maybe tried this before.

Would appreciate any inputs on this ..
Thank you,
DT
