DJM 750 MK2 midi

Hello, I have a question regarding tempo synchronising - now I have djm 700 which has midi out, and there's no problem with syncronising my whole setup (toraiz sp16, xdj 1000, as1, nord lead4, and roland tb-3) , bur now I'd like to buy djm750 mk2 which has neither djlink nor midi out (why...? midi out interface costs 10USD:), question - if I'll set sp16 as master clock, and the rest as slaves, as they are now - will djm 750mk2 play its effects in time using auto bpm from the audio signal of instruments, does it work this way, does it work at all? I gues I'll have to keep some rhytmic groove (hats or kick or whatever) all the time to let djm750 count bpm, am I right? Possibly I can also set the tempo on djm manually and switch off auto bpm, because all my tracks are 136bpm (prog psy trance). What do you think?

Does anybody use 750mk2 for more complex setup?

Or just better buy second hand djm900nxs, which has both djlink and midi out, and that's it?

Thank you in advance for help
