Same tracking. No install.

A stripped-down TSR-01: the desktop app's pinch and rotation maths, ported line for line, driving the filter and a reverb over one of Sterea's tracks. Everything runs in this tab.

what's ported
Pinchthumb–index in palm lengths, 0.18 → 1.15, smoothstep, One Euro (2.2 Hz / β 1.2)
Rotationwrist → middle MCP, ±7° deadband, ~45° sweep, EMA 0.35
CutoffA9 curve: exponential, norm^0.7, per-track range
ResonanceQ 0.5 → 8, eased 0.2/frame; drops to flat when the hand is lost
HPFSame pinch, 20 Hz → 8 kHz top, as in the app. Switch modes in the panel
ReverbH2 pinch open → send level, same direction as cutoff. The app puts flanger depth here by default; reverb is the demo stand-in
HandsH1 = your left hand, as in the app. Swap if the camera disagrees.

The app adds the other hand (slip reverse and beat repeat on wrist rotation), plus HPF/DJ modes, delay, reverb, flanger, sixteen scene FX for the projector, MIDI out per hand and a driver that puts it straight in your DAW's signal path.

Coming soon for macOS. The list gets the download link first.
