I'd take a look at arpeggios 711-714.

Awesome! Thanks so much. I have an MOX6 and just bought an MX49 as a second tier keyboard for live playing, so I can't wait to try these.

Thanks so much for the additional reference to Bad Mister's article. Yes, the MX49 arp 711 UpOct1 is exactly what I'm looking for. Thank you, Andrew and Jason for responding so thoroughly and quickly!
