Jungkook

As shown at 01:51 of MNET's COMEBACK SHOW - BTS DNA Part 1: Compilation of Jungkook, he has RME Babyface Pro audio interface.

From 0:43 to 1:30 in the video, the keyboard can be seen on Jungkook's desk emitting a blue glowing light. Jungkook uses this to often compose music for the song covers he releases for his fans. You can hear it being used in one of his covers of the song 2U by David Guetta ft. Justin Bieber. This video is from their "DNA" comeback reel from 2017. You can see Jeon Jeong-guk filming and giving a tour of his room in this video.

I didn’t want to infringe any copyright, so the link is of the main channel+ of BTS in VLive. You can probably find the vid reuploaded by someone on the internet, for free, if you wanna see it. Its the BON VOYAGE S3 Ep.1.

The evidence can be seen at minute 2:56 of the video. There you can clearly see the box of the maschine mikro mk3 on the floor, right by his side.

Before, at minute 2:04 you can see a box of a maschine mk3 at Jimins and Jhopes room, but i dont know of whom this could be, as Jhope has the studio one and also the mikro mk2... so who knows, maybe Jimin its starting to produce?

As shown at 00:50 of MNET's COMEBACK SHOW - BTS DNA Part 1: Compilation of Jungkook, he has his studio monitors on Primacoustic RX7-HF Recoil Stabilisers.

From 0:48 to 0:52 & 0:55 to 0:57 the Native Instruments Machine Studio is shown on his desk. This MIDI controller allows Jungkook to sample and make beats for his songs & covers.

An RME Fireface UFX II can be seen at the bottom of his monitor

At 2:46, an RME fireface UC is spotted connected to a Lewitt LCT640TS microphone
