As we've discussed before Ted, the major problem with 'shortcut' fingering systems is, once you get heavily (irretrievably!) invested in one, you are completely at the mercy of manufacturers to adopt it across ALL brands (never going to happen, each manufacturer thinks they have the perfect system and their users have boxed themselves in to where they HAVE to agree) or the brand that has the system you have trained yourself in must continue to produce arrangers AND not decide to change it...

That's an awful lot riding on a system that, if you had taken the time to simply learn 'normal' fingering, you would be independent of brand and system! It took YEARS for you to get automatic with that system, and no matter how skilled or unskilled you think you are, ANY system can be learned in years!

Yes, shorthand gives a faster transcribing of dictation than longhand, but years ago there were several other shorthand systems, and no doubt there were many that had picked the wrong system to learn. But I bet that rather than deciding to leave the profession (if others can't transcribe your shorthand, you leave yourself few that can employ you) most of the users of systems that got left behind simply knuckled down and learn the eventual winner.

The shorthand analogy unfortunately rather falls down when compared to keyboard chord recognition, because, while shorthand IS faster than longhand, once learned, 'normal' fingering is just as fast as one finger systems. And considerably more chords can be fingered with four fingers than two or three!

You've painted yourself into a corner. If you're happy enough there, that's okay. But the world of other manufacturers AND the expanding world of software arrangers is out of reach while you cling to a system NOBODY uses any more.

A half an hour a day would have you mastering 'normal' fingering or Yamaha's system in a few months. What's that against YEARS stuck in that corner unable to progress..?

You can do it!
