After exploring the products a bit more I'm inclined to get the XV-5080 (compared to 3080: better display, spdif out, sample playback, COSM, greater ROM and RAM, $400 not big deal to me averaged over years of use) but wish it had an arpeggiator. I don't have a MIDI keyboard controller or any keyboard for that matter. Can I use a MIDImasterkeyboard with an arpeggiator to "arpeggiate" the sounds in the 5080? Do I have to get a full-out cheap synth with an arpeggitaro like like the XP-10 or RS-5 to arpeggiate the 5080? I don't play piano so weighted keys aren't important and neither are 88 keys. Any recommendations or ideas would be greatly appreciated to help arpeggiate the XV-5080.

Someone at Guitar Center recommended the Anatek (?sp) Pocket Arpeggiator?
