I would like to know how many others use the Korg PA50.

Hi:

I think you should consider adding to that list all the PA 60 and all the new Micro Arranger owners..the reason is simple, all this keyboards are pretty much the same.
The PA 60 vs the PA 50, the 60 was made in Italy and had the option to add a Hard drive with an optional Hard drive kit.
The PA 50 and the PA 50 SD are the same except that one has the old Floppy disk drive and the newer has the SD card port.
The PA 50 SD and the Micro/Arranger are basically clones, one is the standard size and the other in Mini, but functionally are the SAME.
Greetings.

By the way, I had for a long time a PA 60, now I have a PA500, a T4, and also own a Micro Arranger.

If you expand the list, I have the PS 60 and MicroArranger

I own and use the MicroArranger on gigs. I have never had one single moment of "buyer's remorse" over the KMA. I often sit with it on my lap while watching TV and playing with the KMA. Fun stuff.
