Hi, all in in the title.
Not implementing PolyAT in Hise will keep all the edrum market away... That's a pity...
They are used in all Roland module to tell that the drummer has grabbed the cymbal to mute its sound( cymbal choke)
Yamaha, 2box, ATV, EFnote, Alesis (not all their product), Gewa... Almost every brand uses exclusively polyAT for cymbal choke.
Definitly somehting that miss in Hise.
