Hi Jack,
First of all, congratualations on successfully posting on this board. I am not a Yamaha PSR 740 owner (I play a Technics KN5000), so can't answer your PSR 740 questions but I know there are a number of Yamaha players on this board who will help you. Where is Banning, California? If it is'nt not too far away from where I live (San Francisco Bay area), I would enjoy performing for your retirement community.
Congratulations on your new PSR 740
- Scott
