I don't have a MODX8 (could have a MODX7 in the near future, though ). But I have a GHS-equipped keyboard, a DGX660, and the keys work perfectly so far. And there are plenty of GHS units around, working nicely (I know several owners of P115 and P125). So I think it is not a matter of the GHS mechanism, it is more a case of the GHS version for the MODX8 which seems to be failing.Fleer wrote: ↑Tue Dec 18, 2018 1:36 amThe least of my worries. Quite pleased I could return it before this problem surfaced. TBH I had some other reasons as well. Found the whole thing too bulky (and the adapter too flimsy) yet still loved the MODX approach of bringing Montage quality to this price category. Definitely appalled that Yamaha is still selling these GHS keybeds when problems have been known for so long. As I wrote, I may be getting a sub $1000 MODX7 once it gets that low.
