Hi I am a guitarist looking to get back in touch with my keyboard skills. I intend on playing mostly blues and contemporary piano. I have played keys for just one show, and it was simple stuff like Coldplay - Fix You, Porcupine Tree - Blackest Eyes, Ozzy - Old LA Tonight. With a budget of 30-40k, what is the best that I can get? I am looking for excellent piano and orchestral patches, good organ tones and useable synth tones. Currently, the Yamaha MM6 is at the top of my list. Any PSR S550 / S700 users here? I had tried a couple of Roland boards in this range and was not very impressed. Any other suggestions?
