Tony.....let me be honest....KORG arrangers will treat you very well BUT you must put in the time and homework and really dig into the OS to get it to sound awesome....everything you need is in the OS you just have to take the time to set it up, sounds, styles, third party style conversions, editing perimeters,Your Own custom SONGBOOK setups, .... the touch screen is simple to use, accessing SMF, Mp3's, is easy also, learning the "LOCK" system to access features, loading sets to user slots, will become second nature after you do it a few times.....but once all the home work is completed you will have an awesome Arranger sounding keyboard. If you get one and need help just email me or call me ok?...good luck...can't wait to get mine here ..
