I'm still just scratching the surface on the MIDI capabilities and combining sounds into layers and splits and recording, but HOLY COW does this thing sound and feel good to play. I have rediscovered my love of just sitting at the piano and playing - anything from classical to pop and some modest jazz. For hours. The keys are beautifully weighted/graded and I can get so much expression out of this instrument - I feel like I'm sitting at a real grand piano. I'm in piano heaven. I have to stop myself from just playing to take time to call up some videos and the online manual to tackle the learning curves on the other features. (And I have to sleep/eat sometimes.) I'm not a MIDI pro (have basic knowledge) so it will take me a while to get comfortable with all it can do but am looking so forward to using this to aid my creativity, as a solo performer, composer, accompanist, and arranger for various types of ensembles.
