Only the good die young....
Kawai VPC1 is worth a look too.....Well time to dig this thread up. I possibly am looking to replace the S88mkII with a controller that doesn't have anything in the center so that I can place the Mac's wireless keyboard there instead.
So far I see that leaves the LMK2+, Hammer 88, and the A88mkII.
From any photo and video, it's somewhat hard to tell the angle that the H88 has on the casing as I'd be concerned about the keyboard moving. The Roland and Doepfer are flat. I noticed Christian doing this same thing with his LMK. I also would need to attach the tiny tablet I use for CC on the left, but that gets mounted down so not worried about pitch angle there.
