A lo-fi vinyl lounge you run with nothing but your bare hands.

Watch the session

Walkthrough: the full session from START SESSION to SESSION MASTERED, recorded in a Quest 3 with hand tracking. That is me playing it, bottom right.

Summary

Night Shift Vinyl is a VR task simulation for Meta Quest that you control with your bare hands, no controllers. You stand behind a warm, mood-lit vinyl DJ desk and build a lo-fi track one gesture at a time. A floating panel introduces the task and tracks your progress, and a slate at the end shows your session time.

  1. Load the record

    Pinch · Place

    Pinch the record out of its crate and set it on the platter. It spins up with a quiet motor hum.

  2. Drop the needle

    Pinch · Swing

    Swing the tonearm over the record. The needle drops, crackle fades in, then a drum beat follows.

  3. Trigger the beat pad

    Poke · Tap

    Tap the orange pad with a fingertip. A piano loop enters on the next bar, locked to the drums.

  4. Open the filter

    Pinch · Twist

    Turn the dial and the muffled mix opens up to full fidelity.

  5. Push the master fader

    Pinch · Slide

    Slide the flat fader along the front of the board from quiet to full volume.

Poke means press with one fingertip; pinch means thumb and index finger together. The next control to use gets a pulsing outline. When the last step lands, the lamp dims, neon pulses to the beat, and a SESSION MASTERED slate offers a RESTART SESSION button. An EXIT GAME button is always available.

Interesting interactions

Tonearm

A real hinge

The script measures the angle of your pinch around the pivot every frame, so the arm follows your hand like it is on a bearing. Let go early and it glides back to rest. There is no button: the position of your hand is the control.

Filter dial

Twist it or circle it

Roll your wrist or move your hand around the dial, in either direction. It adds up the change in angle, so a dropped tracking frame never makes it jump.

Drum pad

Poke, not pinch

The pad cap travels with your fingertip and only fires near the bottom of its travel, so brushing it does nothing. It flashes amber and springs back when you lift your finger.

The record

It cannot get lost

It cannot sink through the furniture, it settles flat when you let go, and if you drop it away from the desk it glides back to the crate.

Hands cannot rumble, so the feedback is in sound and light: a chime on every step, the pad flash, the platter hum and the pulsing outline. I tuned all of this on a Quest 3, where real hands exposed problems the Editor never showed.
