256 polyphony would be nice Donny but 128 will have to do for now because that's all that's available. Except of course the Audya which has 192 polyphony but it only has USB 1.1 plus the price is sky high. That wouldn't be so bad if it also had USB 2.0, better styles and a larger user memory, etc.
Unless something drastically changes during summer NAMM 2014 or winter NAMM 2015 I'm basically stuck between a rock and a hard place. As I stated previously the Big 3 could milk 128 note polyphony for several more years and they might actually be colluding with one another in order to "fix" the polyphony amount at 128 as a way of controlling the market. But as we know that tends to inhibit progress and innovation. We are basically at their mercy and they realize that and therefore they have a tendency to milk certain features and they do it because it's beneficial for
them from a business standpoint. Consumers have to put up with it or go without. In my case, if a keyboard doesn't meet certain criteria I will generally look elsewhere. On the other hand, Yammie, Korg and Roland are betting the farm that most people will take the 'bait' hook, line and sinker. The Tyros5 is probably a good example of that in my opinion.
Now before people start shooting flaming arrows in my direction the Tyros5 does have some new sounds that are in some cases superb but the B3 organs are still sub-par and of course it still only has 128 note polyphony. Again, people complained that the Tyros4 experienced note drop off but Yammie decided it was business as usual. Furthermore, the Tyros5 still costs around $6,000 out the door. The sad part is Yammie is laughing all the way to the bank because the Tyros line continues to sell like hotcakes. Which means that most people obviously don't care about various shortcomings (or the lack of quality control, especially on the Tyros5) and continue to shell out the big bucks for what are at best incremental improvements on the Tyros5 in my opinion. To each his own I reckon.

The Korg Pa-300 has piqued my interest because it looks like a solidly built arranger at a bargain basement price and it also has 128 note polyphony. Once I get the hang of playing an arranger again I will at some point upgrade to perhaps the Pa4x or some other high-end arranger product that will hopefully have 256 note polyphony but obviously I won't hold my breath if you know what I mean.

All the best, Mike
