Djo

Djo is confirmed to use the Casio MT-65, as credited in the Spotify credits for the album "Decide."

In an Instagram post by Djo, Joe Keery is seen using a Sequential Circuits Prophet-5, as evidenced by the photo captioned "Had so much fun making this record at @electricladystudios with my friends. The Crux is out this Friday 4/4 📷: @cjharvey2" posted on March 31, 2025.

In the Tape Notes Podcast episode titled "Stems Unpacked: 'Delete Ya' Full Pro Tools Session Breakdown," at the 8:52 mark, Djo and producer Adam Thein discuss their use of the E-Mu Planet Phatt sound module on the track "Delete Ya."

In this video with GQ, Joe says that the Yamaha Reface CP is one of the things he cannot live without on tour, etc.

In the second paragraph of an article by Felicity Newton for Dork, it is stated that Djo used the Oberheim OB-X8 for the track 'Basic Being Basic,' mentioning that the song "features Oberheim OB-X8 synths." This information is corroborated by an Instagram reel of an interview with Joe for GQ, titled "GQ Beginner's Guide TO DJO'S THE CRUX," where at 1:04, Joe says, "I got this new synthesizer, this Oberheim... 'Basic Being Basic' came out of that."
