From my observations, most folks rarely explore all of the options and wonderful tools that today's arranger keyboards have to offer. I sincerely beleive the Yamaha PSR-3000 is among the most incredible devices I've ever encountered, and every day there is something new to explore. However, most owners never realize the possibilities of their keyboards, both Yamaha and other brands, simply because they don't make the effort to expore the keyboard's operating system and all that it has to offer.
While some of this is due to the horrendous manner that instruction manuals have been composed, an equal portion of the blame can be directly attributed to individuals that are just not willing to do the work. Fortunately, there are forums such as this one, and a few others, where a few folks take the time to delve into the inner workings of their perspective boards and share this information with the rest of the members.
Happy Holidays,
Gary
