In the official music video for "Locked Out of Heaven," Bruno Mars is seen using the Akai MPC 2000XL, highlighting its role in his production process.

In the video "The Making Of Simple and Sweet (Behind The Scenes)" by Jon Bellion, he is seen using the Akai MPC 2000XL at the beginning to create the drum groove. This provides clear evidence of his use of the gear.

A custom 2000XL was used for sequencing the synths on A Color Map of the Sun, as stated by Pretty Lights in this July 1, 2013 Electronic Musician interview.

“I used a custom-made [Akai] MPC 2000XL to sequence my modular synth, but for cutting up my vinyl to sample and arrange it, I simply used the ‘Arrangement View’ in [Ableton] Live or Drum Rack; I love Drum Rack! I use other stuff now, like Sampler and all the NI [Native Instruments] stuff and UAD-2 [plug-ins], but for the album I just used good-old-fashioned slicing and warp pins straight in Arrangement mode.”

There are several more recent pictures of this Drum Pad, but this one is the most clear showing what Drum Pad it is. On this picture Logic says, "2000XL"

An MPC-2000XL can be seen in Nujabes' studio in this picture. The picture comes from this 2003 Sound & Recording interview (of which the magazine printing can be found here), which has been translated into English here.

　当初の制作システムはシーケンサーがMARK OF THE UNICORN Performerで、サンプラーのAKAI PROFESSIONAL S3000との組み合わせ。レコーダーとしてROLAND VS-880を仕様し、ミキサーにはROLAND M-12Eを使っていたそうなのだが、トラック制作へのめり込むにつれいて機材も徐々に拡充していった。

Nujabes’ initial production system was a Mark of the Unicorn Performer sequencer combined with an Akai Professional S3000 sampler. He says he used a Roland VS-880 as the recorder and a Roland M-12E as the mixer, but as he became more and more absorbed in track production he gradually expanded his array of equipment.

「サンプラーはすぐにAKAI PROFESSIONAL S950に移行して、その後は容量やシステムの相性でE-MU E5000 Ultraを使い続けています。あと、トラック制作を再開して１年くらいして、シーケンサーはSTEINBERG Cubase VSTに移行しています」

"For my sampler I quickly switched over to an Akai Professional S950, and later for capacity and system compatibility reasons I started using an E-MU E5000 Ultra. I currently use an Akai Professional MPC2000XL for rhythm sampling—the nuances in the tone sound better to me on that. But I still use the E5000 Ultra for overdubbing samples. Also, about a year after I started making tracks again, I switched over to the Steinberg Cubase VST for my sequencer."

メインの作業スペースの反対側にあるデスク上にはEVOLUTION U-Control UC-16やAKAI PROFESSIONAL MPC2000XL、APPLE PowerBook G4/800MHz、iPodなどがセットされている。なお、デスク下にはROLAND GP-16やAKAI PROFESSIONAL S950などが置かれている

Set up on the desk opposite to his main workspace are an Evolution U-Control UC-16, an Akai Professional MPC2000XL, an Apple PowerBook G4/800MHz, and an iPod. Under the desk are, among other things, a Roland GP-16 and an Akai Professional S950.

Contrary to No ID, Kanye likes to use all the equipment in the room — stomp boxes, classic samplers, and so on. He mainly uses the [Ensoniq] ASR10 and sequences that with an [Akai] MPC 2000XL. When he's done with a track, he sends it to us as an MP3, and I upload these onto two tracks in Pro Tools. In this case Jay wanted Rihanna's vocals to be edited down, so I asked for them separately, and worked with two tracks of music, two tracks of Rihanna, and then Jay cut his vocals to that. The song was originally intended to feature just Jay and Rihanna, but he also wanted Kanye on it, because he felt that it would fit the texture of the song. So one day when Kanye was in New York, he came in at 10am and in two takes he was done.
