Here is my view
I've read lots of the posts and responses to this subject rehashed a dozen or so different ways. It seems the big debate and claim is that Most people that play arrangers and make a living with them are cheaters.
I think what some are forgetting is that we are entertainers first. I think an arranger KB is a great tool. I read some critical responses that some users play the wrong chords and use wrong tempos and voices. Some are accused of cheating by playing single finger chords. Some people are blasted for using Midi file backings.
If the activity directors stop calling, and the patrons stop coming to the gigs, and the country clubs stop calling to book. It's because the unskilled performers and entertainers were found out. They will be weeded out and probably become full time home playing hobbyists.
That being said, Lots of arranger kb players out there are very successful and great entertainers. They may know zilch about music theory, Some may play with midi files, Some may not know a more than 4 chords, Some may even use the 1 finger approach. some may even play every song in the key of "c" or might be singers with minimal piano skills just looking to play along.
The arranger KB allows you to sound like a full band. If you wanna perform a show on a grand piano just to prove your a chopin in training, thats fine. It may come across a little bland and not the best format at a dance or something upbeat
85% of the audience couldn't tell the difference between a dminor and a Zminor.
In my own experience I am a guitarist first. I've been playing for over 25 years. The arranger has allowed me to create my show at myspace.com/kidconcert (Mikey Maestro's Dance Party). If i tried to do that show with a guitar only it would flop. It would be dull and boring. The Tyros 2 has allowed me to take these famous kids songs and give them a polished in your face arrangment. I know for a fact that none of the key players in charge of booking me has ever said ...Hmmm. Mikey's Playing 1,4,5 progressions tonight.
I have managed to get peoples attention and be booked solid year round and asked to come back over and over again.
So I hope I didn't offend anyone.
Just wanted to add my two cents to this ongoing topic...
It's About people leaving your show ENTERTAINED!!!!!!!!!!!!!!!!!!!!!!!!
