Hammer action vs. semi weighted Stage 4

[SuperStage]

I have a NS3 Compact which I use on top of an 88 note hammer action Yamaha P70 and have ordered a NS4 Compact. I tried all 3 keyboards at NAMM and the NS4 Compact feels exactly the same as my semi-weighted NS3 Compact, but it definitely is more responsive due to the triple action sensor. The HA78 and HA88 have the same keybed and feel the same as the previous versions of NS3, but again with the triple action sensors, which are more responsive. If you are a piano player, you will likely not be happy with the compact keyboard and will either want to use it dual keyboard mode with a hammer action controller or choose the HA73 or HA88 versions.
