Wrinkles... You know what? I've been playing arrangers as band keyboards for close on 20 years. Not ONE musician has ever come up to me and said (disparagingly) 'Oh, you're playing one of those portable one finger organs'!
In fact, the large majority, if they say anything at all, it's 'Wow! What is that you are playing? I've never seen one of those before! Sounds fantastic...'
Bottom line is, unless you rub their noses in the auto-accompaniment stuff, they haven't a clue what it is unless you ARE using a cheap Casio or Yamaha BOTL model! My Roland's have always LOOKED 'pro', feel 'pro' and sound as 'pro' as anything from the WS side of the coin. It is still more what you PLAY than what keyboard you play!
A couple of full time WS players with no arranger needs at all have heard me on the G70 and gone out and bought one for their live band work... So much for 'one finger organ'!
