Then You are not playing fair Diki. It's clear that you actually owned tje module versionthis keyboard or a version before you saw this demo. Therefore Any comment that you might make about how good the demo itself was In terms of what you got from it is kind of moot . the demo in fact was of no benefit in helping you make your purchasing decision clearly. In fact you bought the module version for actually very different reasons than most people would buy the keyboard version and you did so regardless as to its iPad functionality it would appear. I can see how the module might appeal to you and a limited segments of the market But surely you would understand the difference between the needs of the person who buys a module compared to the needs of the person who buys the keyboard . its not the same product .Still it's good to know roland made a sale inspite of this awful demo. Perhaps you genuinely are Rolands target market. How many of you are there?
