Adimatis,

As I already mentioned a few weeks ago the vocaliser on the PA900 is ( to the best of my knowledge) the same as the one used on the PA800. It certainly is not identical to the one used on the PA3X and that goes for many more items. As Andrea stated elsewhere Korg can ( and will have) cut corners wherever possible.You may think of hardware such as capacitators, wiring, speakers, keys, but most of all the DAC convertors. Another very interesting item to know would be the amount of MB used for all of the onboard multisamples. Going thru the manuals of both PA3X and PA900 you will find that the samples are identical but this does not mean at all they will sound identical. Critical here are the DAC convertors and the amount of sampling space allocated to each multisample. I have never been able to find out the exact data about this not even on my PA800 but I would be suprised if the overall size of the sampling MB on the PA900 were to be identical to the PA3X.

regards
John

P.S. Uncle DAve, despite all your efforts I hope for you and sundry that you have gotten a defective PA900 indeed as far as the mike input and vocaliser is concerned. Looking forward to what's to come. Best of luck !!
