Look, we can see that even dictators in the Middle East have a problem controlling what gets videoed and what doesn't, these days... Why should some underpaid Korg part-time sales rep (who probably works for another dozen companies, too) be able to control what a brutal dictator can't...?
BTW, it's a long established sales procedure to show a product at a VERY early stage, even if overwhelmingly, to hold sales up of a competitor's products if they get to market before you. Many other companies have done, even to the point of vapor-ware...! At least we KNOW that the PA3X will ship, pretty soon.
What has become disappointing, on this forum, are people who SHOULD know better, expressing disappointment at poor, amateur presentations and videos that fail to match even the PREVIOUS Korg arranger, and assumptions that this IS what it is going to sound like... There's no way in hell that, when the PA3X is released (rather than beta demoed for dealers and the like) it is going to sound WORSE than the PA2X...
So, go listen to a PA2X, and then imagine it with a doubled sound ROM. And give your fevered imaginations a rest!
