All the best to you Paul. I hope your purchase of a Modular works out. Although your assessment of Arranger Keyboards being nothing more than glorified Home Keyboards is inaccurate imo. More people use Arranger Keyboards as their primary Gigging instrument than you can shake a stick at and many Musicians Gigging with them do it for their primary source of income (bread and butter). Also it takes more 'skill' to play a Keyboard than it does to twist a few knobs but if you're not up to the challenge and dedication it takes to learn and play a Keyboard then the Modular Synth is an easier route to follow and definitely the way to go for you. Sorry to hear your change of heart but I hope you'll be happy in your choice of choosing Modulars over Arrangers. PS: The less professional Keyboard players there are means more money for the ones that be!
Eventually Keyboardists may become a novelty act and will be in 'high' demand because of it and the they would be able to demand exorbitant fees for their services.
PS: I hope that never happens, really!
I hope Keyboarding becomes more and more popular and more and more people take up the Keys. Even if it means possibly losing income because of the competition and saturation of the market.
Of course that doesn't apply to Donny. He'll just re-invent himself and continue to make oodles of money regardless of competition or saturation in the marketplace.
I still say you need a good Keyboard to do it though. (Not just you Donny but ANY body).
Best regards,
Mike
