Hi Bachus,
settings might help. I can get good piano on my Korg, but on my psr ( which I’ve just recently started to use, after x number of years) I couldn’t get the same dynamics, had to hit the keys really hard. Thought it was just the keyboard, then it occurred to me about the setttings changed it from medium to soft and what a difference it made. Don’t think I’ve ever tried changing default setting before on my keyboards, or even my ex Clavinova.
