The Steinway models are what I use the most and especially the model D. I also purchased the Hohner Clavinet pack. Yes, you should calibrate the velocity to your playing. Also very important: Pianoteq has a built-in EQ and you can make subtle adjustments that make a huge difference for live playing whether in a jazz or rock context. I have custom presets that adjust the parametric EQ accordingly.
I use Pianoteq for all my piano and Rhodes sounds. My favorite is NY Steinway D with some EQ, depending on the song. Bösendofer is very beautiful, but in my band it can’t compete with the guitars. The MK-I and MK-II work fine. The same goes for the CP-80.
For the longest time, I’ve been using a layer of Kontakt Gentlemen with some chorus and a subtle layer of Addictive Keys CP70 underneath. It added just enough detune to make it stand out. These days, when I want a “real” piano sound, I’ve actually been using the EastWest Bechstein piano. The Pianoteq stuff is great and all, but a lot of those subtleties get lost in a dense mix, so I’m usually going for whatever cuts live. Oh and I’m almost always straight mono live. It’s just simpler.
I currently use a hybrid set up of Nord Stage 3 plus GP. My go to piano sound for our rockier numbers at the moment is the Nord’s on board piano with Kontakt’s Grandeur Piano. And as has been said a few times, you really should try stereo in ears. It sounds great.
It’s funny, when I’m playing live (with in ear monitors), I’m happy if I can hear myself above the mix and hear the rest of the band enough to know where everyone is in a song. Trying to get the type of hi fi experience I might want at home does not really make it on my agenda!
Decent molded IEMs with multiple drivers allow you to hear yourself and the band at living room levels with extremely good clarity — AND they protect your ears.
