This poly-at keybed designed by Sequential will be used in another keyboard synth as well besides the Fourm !
From this article in CDM. ( Thanks to cutlery for linking this article over in the Fourm thread. ) :
Oh, and by the way, if you’re hungry for more poly-aftertouch keyboards, you heard it here first from Sequential’s CEO: “We’ve already started the design of another instrument that will use the same keyboard, because we feel like this is something to invest in and keep moving forward with.”

The article also relates how closely they had to tune in the outputs of the p-at keybed into the control electronics of the analog synth. ( In the digital Hydrasynth adjustment of the modulation matrix is left to the patch maker. )
ADDED : I am interested to see how well the Fourm can perform as a controller. That is something the Hydrasynths do well. It is a challenge to design both together.
