The metropolis is very nice and interesting indeed, but I would like to have hands on single 16, or more, step for sequences (8 steps would be nice just for the cv). The pressure point array is also very interesting too but again, is 3x8 only it would awesome to have also the option of 1x16 + 1x8 or 1x24 .
The space it's also a problem, for the sequencer I've planned something about 34hp, if it's worth I can sacrifice some utility modules and find some more space but not more than 2-4 hp...
The external sequencer it's a good option too, the beat step pro looks amazing! and in case I would also have space for other modules (SYNTHESIZER BOX from Pittsburgh Modular would fit lovely!).
Any other suggestion?

Thanks a lot for the help!
