Seen above the KTG-1. I believe this is the vocoder/sampler Kevin explained as the "vocoder" effect in "Let It Happen"

'"Let It Happen," there's this part at the end where I'm singing through this keyboard sampler thing, almost like a vocoder but not really" (http://undertheradarmag.com/news/tame_impalas_kevin_parker_discusses_let_it_happen_in_cover_story_outtake)

**after a bit of research and watching a few videos, this is definitely what he used on Let It Happen.

A photo of Daft Punk's studio featuring Guy-Manuel de Homem-Christo shows a Roland VP-9000, identifiable by a yellow square and arrow.

*The other important piece of gear in Shadow's setup is a Roland VP-9000, which he uses for its time-stretching and internal effects to morph a mediocre sound into a great one. * “What the drums on ‘Walkie Talkie’ are now and what they were on the record are totally different,” he says. “On the original record, it's just sort of average-sounding, and it actually isn't even a drum break. It just goes, pssssshhh, kuh-boom-boom, and then the vocalists start singing again. So I took that, put it into the MPC, made a fake pattern, put that into the VP, gave it all this huge weight and distortion with the internal effects, plugged it back into the MPC, re-chopped it and made it sound completely different.”

Roland VP-9000. it was ableton before ableton. Such an amazing box, even to this day. their time compression / expansion and pitch shift algorithms are still top notch to this day.

Mentioned in a "studio gear" list in a 2001 interview with Rocket Baby.

In an Instagram post, Octave One shared their experience at Analog Room Dubai and mentioned their upcoming performance at Concrete Paris. The image accompanying the post features the Roland VP-9000, a key component of their DJ setup.

Madonna utilized the Roland VP-9000 on her song "I'm So Stupid." In reference to this track, it was noted: "I am thinking of a track like ‘I'm So Stupid.’ That is one of the most innovative tracks on the album. The vocal starts very gently; then, I freeze it using the Roland VP-9000. It is the only machine that can do this. It is not a sample loop; it is a freeze. When she sings ‘Aaaaaahhhhhh,’ the vocals freeze. It is a gently modified track. It sounds natural, but it is not natural." This information is supported by the article titled "COVERT Operation" from Remix Magazine.
