Arpegiator to single cv track - possible?

I am sure I set up a monophonic sequence of single notes, and had a harmoniser effect followed by an arpeggiator effect, and the result was an arpegiated sequence at the cv out of the track. But I can’t seem to recreate it. Did I make up this is possible? I should be able to turn a monophonic sequence into an arpegiatted pattern that included what ever extra notes I have chosen on the harmoniser effect, right?

should work exactly as described. Input your notes, add a harmonizer effect with the desired chord, add an arpeggiator after that.
