Hello again...
First about arpeggiator. There is a very capable arpeggiator but only on XV88 keyboard. It has 45 preset styles with regular chords or lowest/highest note progression. Most of presets are chord / quitar patterns nice for modern and classic parts.
XV88 apreggiator sends midi notes and receives midi clock sync. It's much like Yamaha S80 arpeggiator. User can use matrix editing parameters and slider/D-Beam controllers to live control its functions. Do not expect too much from XV arpeggiator. XV88 has no onboard SEQ so it has some limited (but excellent sounding) arps. If you have experience from XP80 or Yamaha S80 arpeggiators you know what you can expect from XV88 arp. I must admit that it sounds more natural than the above keyboards.
Cosmic Dreamer i think that we share the same studio setup

I also use Triton + MOSS + XV + other and found their audio combo excellent. Using those boxes in my home studio i have better sound than five years ago using a whole pro studio. Yes Triton has great specs but real poor realistic sounds (like piano

Using an XV things change to better for both of them, especialy if you drive XV outputs to Triton FX inputs (!)
I've tried such combinations and found that twenty four hours in a day are not enough

. Sometimes i missed my old wood piano without DSPs CPUs etc. That time i had scores in front of mine, now i have service manuals and circuit diagrams, monitors, bla bla bla...
See you soon...
PS: If you want onboard music pattern programming, sequencer with MC80 functions, disk drive, large LCD and other workstation gadgets wait some months for the new Roland keyboards line. I'm always looking for "inside" information.
