Oh Sherrie: would like to program arpeggiator for intro

[mojo2000]

I have a Triton Studio 61 and would really love to program the arpeggiator to help me play the intro to Steve Perry's "Oh Sherrie" live and in real time. Or a reasonable facsimile. Can anyone help, please? Any tutorial pointing me in the right direction would probably help with Corey Hart's "Never Surrender" also...

I know I'm asking about an older model and an older song, but IMHO they are both timeless and deserving.

Yes, I'm aware I could just sequence multiple layers into a short song, and also sample the end result for easy triggering, since the keyboardist opens and closes this song alone. But there's just something about live, dynamic playing...
