It is important to remember, that besides from the sequencer and interface, the XP-60 and XP-30 are identical. They have the same synth-engine, effects processors etc.

The XP-60 is more expandable, with 4 expansions. Besides, the floppy drive is, in my opinion, an advantage. The XP-60 has a much better interface.

The internal sequencer on th XP-60 is great in my opinion. I use only this. But if you want to use computer, you really don't need this.

On the plus side for the XP-30, is that three expansion-boards are included.
