The latest free upgrade (1.30) to the Skoog musical instrument brings "Skores" to life. Within this new feature, you can select a song from a drop down menu, then play guided by a flow of coloured shapes. It works really well in practice and will help a lot of musicians who find traditional music scores far too difficult.
Excitingly, I hear rumours of a one-side to play musical Skores in the works. Can't wait to see and try that out.
