I get paid for actually making music using many brands of keyboards, synthesizers, arrangers, whatever brand I need to get the job done right. I'm not a one trick pony nor would I ever be swayed by a paycheck to feel any obligation towards one brand. If a client wants to hire me they do so because of my abilities and my expertise, not because I use brand X or brand Y.

It's clear to me and anyone else with two eyes Ian that you are so entrenched up Yamaha's derriere that you can't see straight. Must be pretty dark up in there. Hopefully you have a Yamaha flashlight to help you make your way in the dark.
