A modern Windows control center for Turn Up mixers and the TreasLin / VSDinside N3 stream controller.
Per-app audio, profiles, RGB lighting, room sync, tray mixing, macros, and stream-controller workflows.
Amp Up is a Windows-only open-source replacement and upgrade path for the original Turn Up USB volume mixer app. It keeps the simple idea that made the hardware great, then adds the things power users kept wishing existed: per-app audio control, smart profiles, RGB effects, room lighting, Stream Deck-style actions, a fast tray mixer, and a modern dark UI.
The 1.0 beta also adds native support for the TreasLin / VSDinside N3 stream controller, turning its LCD keys, side buttons, and rotary encoders into a second control surface inside Amp Up.
- Download
AmpUp-Setup-1.0.7-beta.exefrom Releases. - Run the installer.
- Launch Amp Up, then connect your Turn Up mixer or N3 controller.
Close the official Turn Up app first. Only one app can hold the Turn Up serial port at a time.
Amp Up supports Windows 10/11.
The experimental macOS alpha has been discontinued and removed from the repository due to lack of user interest and the maintenance cost of keeping a separate Core Audio/Avalonia port healthy. Older macOS alpha builds are unsupported.
| Device | Support | What Works |
|---|---|---|
| Turn Up USB Volume Mixer | Stable | 5 knobs, 5 buttons, 15 RGB LEDs, profiles, per-app volume, lighting, macros, tray mixer |

Amp Up speaks the Turn Up serial protocol directly over the CH343 USB-to-serial chip at 115200 baud. Knobs can control master volume, input gain, individual apps, app groups, device volume, active-window audio, monitor brightness, and more. Buttons support tap, double-press, and hold gestures.
Amp Up includes native beta support for the TreasLin / VSDinside N3 stream controller. The N3 has 6 visual LCD buttons, 3 tap buttons, and 3 rotary buttons, making it a great compact companion surface for audio, macros, media, apps, and stream controls.
N3 support is designed to be self-contained, with no long-term dependency on VSD Craft for day-to-day use.
