2 years of playing/learning Piano on Casio CTK 4000
just playing random stuffs on the occasion of completing 2 years with my first piano/keyboard :) (finger flexibility has definitely increased, but not much progress in terms of piano playing as I do very little practice in last 1 year and haven't learned to play any new songs, though I managed to make 49 music tracks in these 2 years with VSTi technology ) :)
