The HP76 (Hammer Portable) is Fatar's TP100. You'll want lighter action than that.
The Nord Stage 2's HA76 (Hammer Action) has the TP40L ("light") keybed. I found it just a little bit lighter than the Forte 7's TP40 action.
The great thing on the Stage 2 is that you also have 3 more Dynamics level choices -- each one making it progressively easier to hit max velocity.
Normal
Dynamics 1 - slightly easier to hit max velocity
Dynamics 2 - even easier to hit max
Dynamics 3 - easiest to hit max
In other words, for your left hand, you can set the response to Dynamics 3 to play lightly and still hit the loudest piano notes. Gradually, as your left hand gets stronger, you can ease down to Dyn 2, then Dyn 1, then back to normal, until your hand regains full strength. Even then at Normal the keybed is a joy to play.
And that's separate for the velocity curves you can set for its 2 External channels. The Organ section also has a low / high trigger option.
And the Stage 2 can download the latest pianos as Nord offers more upgrades. The latest is the White Grand, and I've got the Large versions of it and the Silver, as well as a couple other Medium grands.
I got lucky and found a Nord Stage 2 HA76 for just around $2k last year, soft case included. Maybe you could get lucky if you're a little patient.
I have to say the Stage 2 is a great match for the Kronos 61. I hooked up all my pianos so I could test play them from the Stage 2 keybed. Of the various pianos on a Kronos, PX5S, Integra, Forte, and MODX7 (tested stock pianos only), I liked the Stage 2 pianos best by far. The Stage 2's synth is pretty strong sounding as well.... a nice addition to the K's VA engines.
It took quite a bit of research and a couple near misses to finally land on a great 76 key action board to pair with my 61 key Kronos. The Forte 7 was a close runner-up, but the Stage 2 won out due to being lighter, smaller, same or better action, and much cheaper to boot. HTH
The Nord Stage 2 HA76 sounds like a good fit for me. I will start looking to find one. Like you said, the sameTP40L keybed, as in the highly recommended Forte 7, sounds good to me. Thanks for your help in finding another board with a light hammer action I am looking for. Still going to look for a new or used Forte 7 as well, and try the GrandStage 73 as others recommended.
