What type of synthesizer/effect is used on this Drake's Hotline Bling remix?

Question

On this Drake's Hotline Bling covered by Charlie Puth & Kehlani then remixed by Wildfellaz & Arman Cekin, what is the effect used at 1:22?

Answer 1

That's Antares Autotune, processing an enveloped repeating sample. It's a sweeping arpeggio - that particular technique is the same you so often hear in American pop R&B these days.

It could also be a Vocoder, but I'd wager my ruples on Autotune.

Answer 2

It definitely sounds like a vocal sample processed through something, maybe a Pitch-Shifter plugin and a Tremolo plugin. I guess the pitch was changed either by a knob or a pedal maybe.
