As far as I know newtek.com doesn’t make a Syphon2NDI app?
The fastest way to check your network, firewalls and NDI sender is working correctly, is by downloading Newtek’s free NDI Tools (available for mac & windows) and then run the NDI Studio Monitor application on the receiving computer. newtek.com/ndi/tools/
ok, that’s good. Well in that case, instead of trying to get that Syphon2NDI app to work, why not just load a TouchDesigner file on the receiving machine, containing only a NDI In TOP wired to a Syphon Out TOP - who needs another app
