easy? - very.
long-winded? - somewhat.
you can save lots of time with the EMC software program, but then that costs, the disk comes free with the keyboard. The EMC is great if you have thousands of conversions to do. But Gunnar, and others like Bud Whipple here may have done a few for you already? The style converter disk is a nice no-cost plus if you want your favourites from some other previous keyboard carried over. But remember the tweaking. They come out good, but not perfect. You need to balance, add DSP, maybe change a voice or drum kit here and there to get something that sounds comparable to the built in presets, it's like this for any conversion.
