If he had practiced along the way. (life's Journey) he could have played the royal. The Cubasis was talented but had no time for him. Too busy finding the right DAW the one he used was to easy so the ability to learn had evaded him. At the end of his life he realised that using so many different things (APPS) was not the answer but fine tuning his art and utilizing others would have helped him to fulfill his dream!
Instead of looking at the Royal Albert he could have been playing. A DAW Software is in nowise any comparision to mastering your guitar, piano, Cello etc. etc.ect
