Although trained as a pianist, I played all the other electromechanical keyboard and synths as a gigging keyboardist back in the days when there were no alternatives, no arrangers, no workstations, no controller keyboards. And by doing so, I found that the actions themselves became part of the sound. They defined what you wanted and COULD play on them…

I have a huge problem doing ‘normal’ organ techniques on fully weighted piano actions. Same with clavinets, synths etc.. Even Rhodes FELT and played rather differently than a piano. But organ especially, with the heavy palm smears, do it on a piano keybed and you’re soon slicing your hand on the sharp corners that take far more force to depress than a waterfall keyboard..!

Each sound needs its own action, and given that piano is just a small percentage of the sounds a gigging keyboardist uses, when faced with the need to not lug around two keyboards (with a double stand etc.) I go for a 76 plastic. Yes it’s not optimal for piano, but in truth, it’s optimal for 80% of the sounds I use. I’m not sure of the wisdom in using an 88 fully weighted action unless you play 80% piano… 🎹😎
