Yep... Sometimes I feel like the one-eyed man in the land of the blind!

It's not that I am THAT great a player (if any good at all!), but so many arranger users are one finger chord players, barely getting the melody and chords right, or just fairly basic players. And issues that prevent you being able to whiz around with BOTH hands when you feel like it, or chord recognition systems that don't account for more elaborate passing chord systems, or ways to defeat chord recognition while you chromatacize your little brains out all over simpler changes, just get blank stares and complete non-recognition that there IS a problem!

But for more advanced players, there are a myriad issues that don't trouble basic players, but getting them to acknowledge that, although they may not be a problem to them YET, if they improve a bit more (and who doesn't want to improve any? ) they WILL sooner or later face these problems is like pulling teeth

'It works for me NOW, so how could there possibly be anything wrong?' is the mantra. Well, I'm here to tell you that, get any better than you are NOW, and you WILL find problems with these supposedly 'perfect' arrangers!
