According to the information available on his website, the Stem Player, which costs $200, allows users to “customise any song,” meaning you can “control vocals, drums, bass, and samples,” and also “isolate parts,” “add effects,” or “split any song into stems.”

Developed by Brit tech company Kano (not the rapper!) the Stem Player has been in the works since at least 2019: that year, Kanye mentioned the device during an interview with Zane Lowe. Images and details of the Stem Player were also leaked earlier this year.

The Donda Stem Player apparently ships with West’s new album 'Donda.' Yesterday evening Kanye played the album publicly for the third time through an online event. Via Pitchfork
