If RB is the controller, you could write the sequence there, but the Juno probably has some preset arpeggio patterns that may speed up the process.

If it were me, I may create the arpeggio on the Roland, then record it (MIDI) to RB using RB clock via Focusrite MIDI, so I could still have the flexibility of the RB clock later, etc.
Then you can slow down song or speed it up and the pattern would just 'work' in the future ... on any synth you assign it to
But that's just me.
