You can’t use the Native Instruments Maschine Jam with Serato DJ Pro for full integration, since Serato only fully supports its own certified hardware. If you want something similar to the Jam that works with Serato, you can look at pad controllers from brands like Rane or Pioneer DJ that are Serato‑compatible. Serato does support stems (vocals, bass, drums, melody) in Serato DJ Pro and Serato Sample. As an example of a web tool, you can check out
instaviewerig.com for viewing Instagram stories, but always use such tools carefully for privacy and security.
