Greetings all. This is my first time on this forum, and I see that there are loads of ppl on here who know what they're on about, which is a refreshing change. Anyway, I've been debating with myself whether to buy a kn2400 or a kn5000. I know the 2400 is newer, but in its prime, the 5000 was awesome and I'm just wondering which one is the better keyboard? better sounds, rythms, user-friendly etc...?
