My advice would be to first and foremost play on the mpc that affords you the best control, tone quality and intonation over the natural range. How responsive a mpc is to the harmonics/altissimo is a secondary concern for me. It may be more important to you though, so it's tough to say.
If you like your current setup for all other reasons besides overtone response, I'd say stick w/ it and hack your way through. Are you playing on a large chamber/low baffle piece? I think it's generally true that higher baffles and smaller chambers make overtones easier, but they come w/ a totally different feel and tone quality.
