Hi,

The Korg X50 doesn't have an internal sequencer so that one is out.

The Triton LE has a sequencer but is not the easiest to get around on.

The Trinity is good, but for the type of music you are interested in I think there are better choices.

The PSR-500 is not a workstation, it is an easy play keyboard that has a number of built-in styles but you really can't create your own sequences from scratch and the sound-base isn't going to lend itself to your style of music.

The MM6 I am not too familiar with so I can't really comment.

The winner in my opinion hands down is the Roland Fantom XA. A very good sequencer, great sounds especially for the style of music you are doing, sampling, good display, etc.

Good luck in your search. If you decide on something else please let me know who is selling the Fantom as I would be interested in it. Thanks.

Dave
