On OS X this only works for me when I press a midi key. The metro(1) does not seem to do anything… ---

Sorry, I have instr 1 running all the time. It’s not midi driven. But I’m trying it with plain old Csound. ---

Ok, I was able to get around that error message by passing an IP address instead of localhost. Still can’t see any messages in my OSC monitor though… [edit] right, now I’m seeing something in the monitor. Next, I’ll try this with Cabbage… [edit] so this just bring Cabbage crashing. The debugger brings me to the Csound library. I’m not sure what’s causing this… ---

I guess Csound needs to generate audio, even if it is dummy (level 0) I’ll try that soon. ---

Ok, the problem was that you omitted the `NULL` in your `-+rtmidi` CsOptions flag. That was causing the crash for me. So once I fixed that it all work as I expect. ![OSCTest](https://forum.cabbageaudio.com/uploads/default/original/2X/0/0021add7666f5e5c2d77db69997137670932b253.gif) ---

And so it does, sorry for the fuss. As a thank you here’s my story about the alien encounter my wife and I had 2 years ago. Slightly Off topic, but very interesting…[https://medium.com/@zappfinger/pictures-of-exoplanets-appear-on-cameras-during-ufo-sighting-9520b390812e](https://medium.com/@zappfinger/pictures-of-exoplanets-appear-on-cameras-during-ufo-sighting-9520b390812e) ---
