anyone know what synth this is?

I think it's a PT-10.



It's most likely not an arpeggiator, just a very simple single-note sequencer; by letting through a clock pulse you can advance it one step. The intro basically shows him programming the sequence.

I have no idea whether the "advance one step" is a modification - but it should not be that complicated. You could do the same by quickly enabling/disabling the clock (but you'd have to do it without resetting the sequence so that it'd play from start again).

looks like it's a regular feature of the unit (the "one key play" button).
