The patch itself looks fine. Does the stand-alone version work correctly? If so you might try re-installing it. The VST install defaults to C:\Program Files\Steinburg\VSTPlugins. Perhaps you have the old VST coupled with the new standalone version. I would remove any copies of the VST before reinstalling to make sure the new VST is installed. If you post your patch I can try in on Reaper.
I also reinstalled Audulus and nothing happened
I tested your patch and got the same results in Reaper. It looks like the keyboard node is not receiving any MIDI messages. Because it defaults to 0 Hz, the oscillator is essentially stopped and you don’t hear a sound. If you disconnected the keyboard module outputs and bypass the level node connected to the ADSR, you should hear a 440 Hz tone. I’ve informed @taylor of the bug.
