I figured I'd chime in here. The Korg PA800's sequencer is also clearly more sophisticated than the Roland E-series of which I own an E-50. Of course...it better be as it's twice the price! I've been reading the PA800's manual lately and am very impressed. One of the things I really like about the Korg's are that when you go into the Quick Record Backing Sequence and record something with a given Style you can go into the sequence later via event view and change styles like you would change program/bank patch events. This means you can change on a dime style changes. You can't do that with the Roland sequencers that I know of. One might say "I can do much more within my DAW with an external sequencer" but I like the idea of getting maximum ease and flexibility with these onboard sequencers for fleshing out most of the song and not have to muck about with the PC. The Korg sequencer seems very intuitive yet powerful. On the Roland's there are basically 2 ways to sequence midi events. Recorder vs 16 Track.The Recorder can record 16 tracks at a time but if you attempt to then overdub 16 tracks halfway through the song you realize it doesn't work. It simply starts at the beginning and erases what you just recorded. Inversely, the 16 Track sequencer method only allows overdubbing one track at a time. Huh?? What about 16 tracks with unlimited overdubbing with any amount of tracks? The Korg kills this in every way especially considering it's ability to change styles within the sequencer. Very well thought out.
