Pro is short for professional as used here. Professional means one that has expert skill in his or her endeavor. Be it a doctor, musician or what ever. In other words one who has attained proficiency in what he does. There are other definitions of course but the question here is what is the difference between a pro keyboard and a non-pro keyboard. Other than a company adding the letters PRO to one of their products to play to the purchasers ego and or market share I would like to offer my thoughts. hopefully in laymen's terms. Just as people are labeled pro or professional in the sense of attaining proficiency, so also with equipment. Take for instance the tools of a mechanic or tradesman of any profession, other than the wood butchers or alley mechanics and such, these indicate the real professionals in there trade. Their tools are always first class, tools that they can work with day after day with little trouble and that can produce quality work results. Accurate. Long lasting and are a pleasure to work with. With these thoughts in mind, like professional people, professional keyboards are the ones that have proven to have attained proficiency in what they do. Proficiency in the operating system for the task it performs. Pleasure to use. Reliability. The proficiency to give the people it is designed to please to experience to finest sounds that can be sampled, digitized and heard by the human ear. Last but not least is the ability to allow the performer to attain these goals with ease and pride in his many years of practice towards this end. Of course there will always be those who are willing to sacrifice these qualities to other gods. The god of weight. The god of cheapness or the god of good-enough, or, brand is another god and so it goes. That is how I see it and I am sure others have different spectacles to view this with. Oh, I almost forgot, the god of ignorance.
