- The Wall
- A circular room seen from inside: your Riffmixes hang as plaques along a shelf. Tap one to dive into its deck; the + slot births a new blank Riffmix.
- The Deck — a radial piano roll
- One spinning disc, twelve concentric diatonic lanes (B3–F5). A note is an arc on its pitch's lane, and a row of lane-colored beads marks the playhead on a shared 16-beat wheel.
- The house drummer
- Drums never arrive blank — BeatSmith presses a groove that's already playing, and a shuffle glyph re-rolls it into another recognizable classic.
- Sign it, press it, show it off
- A signing pad drops over the playing deck and the disc itself becomes the paper — draw your signature right on it, then export a square video to the share sheet.
