Hi John,
Thanks for your comments - they are appreciated

I bought the Korg MA back in March this year, just out of interest and have been experimenting with it over the past 5 months. No matter how I try, I just cannot get comfortable with the OS. I even printed out the full manual, but as Audrey mentioned, like many other user manuals - including Technics - they are badly written and often do not explain fully how to achieve particular operations. A good example of the shortcomings of the KMA system : To load a completely new song set-up from an SD Card on the KN7000 takes as little as 3 or 4 button pushes and the new set-up is ready after a couple of seconds. On the KMA, you virtually have to 'jump through hoops' to achieve the same result......
I realise that every manufacturer has different ideas about how a keyboard should work, but I still maintain that the Technics range - going way back - have always been the most friendly and intuitive operating systems. When moving up through the 'Top of the Range' KNs, the OS remained essentially the same even as new facilities were added to the next model, so the learning curve was fairly minimal.
As far as connecting the KMA via MIDI to my KN7000 to allow the use of the KMA styles and sounds, that is not really of any interest to me. I much prefer to make my own styles in the KN7000, which are suited to a particular song/tune, rather than use the 'stock' 4 measure repeating styles, which get a bit boring after a while. I also frequently 'make' my own sounds as well to suit the song I'm playing, either starting from scratch using the excellent samples in the KN7000, or modifying an existing KN sound. The editing facilities within the KN7000 are just so comprehensive that the sky is the limit !! Trying to do a similar thing in the KMA and the Tyros is a bit of a nightmare.......
So, although I've had a bit of 'Fun' with the KMA - and I use the term loosely

- I'm afraid it will be for sale in the very near future and I'll use the proceeds to buy something less frustrating - Like a few bottles of fine Malt Whiskey.......
