Hypno is capable of broadcasting NDI video from its front micro USB port. This allows you to capture, stream and monitor Hypno’s output directly on a PC without additional hardware. That video input can also be routed into OBS, a popular open-source video recording and live streaming program. Follow this guide to set up Hypno with Windows, NDI Tools, and finally OBS.
- PC running Windows 10 (Windows 7 untested for now but should work ok)
- Supplied microUSB cable (after market cables may cause power issues if length > 6 ft)
- Eurorack power supply or USB power supply (optional)
- NDI Tools - NDI Tools | NDI.tv (requires email)
- RNDIS driver - https://modclouddownloadprod.blob.core.windows.net/shared/mod-rndis-driver-windows.zip
- OBS - Download | OBS
- OBS NDI plugin (for Windows) - obs-ndi - NewTek NDI™ integration into OBS Studio | OBS Forums
Setting up and testing your NDI connection:
- Install NDI Tools, make sure to check the box for Studio Monitor in the installation configuration!
- Connect Hypno to your PC using a microUSB cable from the front USB port and allow Windows to automatically install drivers
*On some systems it is necessary to install the RNDIS driver. Please follow this detailed guide: Troubleshooting Windows Connection - MOD Wiki
- Reboot your PC
- Open NDI Tools “Studio Monitor”
- Click the top left hamburger menu and select Hypno:main
- Hypno should now be viewable from Studio Monitor
If you’re unable to view Hypno in Studio Monitor or complete the initial connection/installation, you can attempt the following steps:
- Some USB ports may not deliver enough power for Hypno to run on alone. Try connecting Hypno to a power source, such as the Eurorack power header or the side USB port.
- Swap for another microUSB cable & make sure the power supplying cable is less than 6ft. (longer cables cause voltage drops)
- Try installing the RNDIS driver if you have not already done so Troubleshooting Windows Connection - MOD Wiki
- VPNs may cause issues, disabling them can resolve connectivity problems.
- In some cases, disabling Windows Defender Firewall for Public Networks resolved connectivity issues. Not recommended when connected to public Wi-Fi networks (school, work, coffee shop).
Setting up OBS to use Hypno’s NDI video source
- Complete and verify NDI setup above
- Install the latest version of OBS from www.obsproject.com/download (tested working with 26.1.1 as of writing)
- Install the latest version of obs-ndi plugin from obs-ndi - NewTek NDI™ integration into OBS Studio | OBS Forums (testing working with 4.9.1 as of this writing)
- Next we need to access the individual firewall permissions in Windows through the Start menu
- Look for OBS in the list of applications. If “Public” is unchecked next to OBS, click on “Change Settings” and then check the box. Now click OK.
- Open OBS
- When adding a new video source, “NDI Source” is now available
- After it’s been added, double-click on the NDI Source in the Sources box to bring up the device options. Select HYPNO (main).
- Press OK. Hypno should now be viewable in your main output window.

Quick tips for OBS and Hypno
- With no HDMI output connected, Hypno will output 720x480 over NDI. If the HDMI is connected, the NDI output resolution will match the resolution of the HDMI output.
- You can configure OBS to capture Hypno’s output to any resolution you like in the settings.
- Use the Transform right-click menu to flip, stretch, fit, rotate and center your image.
- Experiment with filters from the right-click menu to apply color correction, sharpening, or use masks and keys.
- Use OBS Virtualcam to send OBS’ output to other recording or processing programs that do not accept NDI OBS Virtualcam | OBS Forums
- Use NDI virtual input (part of NDI tools) to put Hypno directly into any application that supports webcam input.
Hypno Kit built with a Raspberry Pi 4 will not initialize NDI unless an HDMI cable is connected and transmitting signal when the Hypno is powered on.
