Hi Rikki, hope things are going well...
Hi Willum,
Technote should now be shipping a new software series for KN7000, PR804 and PR604 consisting of rolling music score in the screen songs. You can sing along to the lyrics of the full arrangement, play right hand, play left hand, play both hands, busk an accompaniment yourself, slow the tempo to learn the song from the in tempo rolling leadsheet in the screen etc. The presets have been used in an extremely sophisticated way to give an arrangement comparable to any midi file and possibly even better than most if you listen to the total sound
