Me, I’d go for a nice B3 over the theater organ, but I get your point..! 😂🎹

Curiously, my old Kurzweil K2500S has a 76 action that splits the difference between synth action and piano, but it still retains the piano’s sharper edges, and to be honest, so do most synth actions. Heavier than any synth, lighter than most pianos. It works pretty well, and with full sized keys it allows me to be fairly pianistic on it (getting up in between the blacks when needed e.g.). It’s not a waterfall, but the lowered resistance helps to not snag your palm during smears and falls.

I think it’s a Fatar action, but I haven’t found it on anything other than Kurzweil’s…

As to plastic actions, I absolutely LOVE the action on my G70’s 76. A fraction heavier than say a PA4/5x 76 or most 61’s, but the main thing was firstly, full sized black keys, and secondly, the dropped the stupid fake plastic overhang to the keys, so despite not being a true waterfall action, there’s nothing to snag your hand doing smears.

Roland used this action on the G1000 (a fraction lighter, maybe a lighter spring), the VA76 the G70 and the A70 controller keyboard (got one of those!), but all modern Roland’s are using Chinese actions, and they cannot replicate this action (possibly because it was more expensive and heavier than they want nowadays).

So there’s two GREAT actions no longer available. 🥺

Even more troublingly, several new keyboard workstations are coming out with full 88 piano actions, but the middle size 73/76’s are also fully weighted piano actions, meaning only the 61 is a synth action. I cannot understand that logic… if you want fully weighted, it’s because you’re a pianist, and if you’re a pianist you NEED an 88. But the 76 synth weight has long been the ideal action for a gigging keyboardist needing room for BOTH sounds when split (and enough notes for a reasonable piano part) and a light enough action for the 80% of his gig that isn’t playing piano.

I hope this trend doesn’t become the norm…
