Hi Marcel, WELCOME to the Synthzone arranger forum, I concur with Squeak. I would say if you're serious about playing solo piano, then it would be most beneficial to invest in an acoustic piano, or a digital keyboard or synth which has 88 'fully weighted' keys. The advantage is that you'll have much more control of dynamics, running scales, etc, developing a solid foundation of good pianistic technique which can then be transfered to synth arranger playing. Though you can certainly play piano sounds on a synth action board, you won't be able to accomplish what you can with fully weighted keys. Good luck with your piano lessons. PS: You might consult your piano teacher for a recommendation of a piano (acoustic or digital) to best suit your needs. - Scott
