I have the exact same result. I don’t understand it. I made a new thread to try to discuss this with the mod devs. OSC on the Mod (or why mod-host doesn't like my midi port) - #2 by gianfranco - Developers - MOD Audio Forum
I have tryed several OSC app, on both osx and android phones, nothing seems to work. Finally i’ve installed TouchOSC that seems to be a very good app: connection seems to be properly set, but even in this case osc2midi -v doesn’t show any message.
I suspect that they are not matching the mapping file. Have you looked at the documentation of osc2midi at all? Because OSC is such a broad and flexible standard without a common implementation, each app does it a little differently. You just need to make a .omm map file for your app. You can see all the OSC messages received if you run osc2midi -mon the -v just prints the matches made, -mon monitors/prints all received messages. I’ve been successful for sending OSC over bluetooth and over the usb from my laptop. Keep in mind that with android you should disable your other networks (mobile data, wifi, just like if you are using the pedal builder webUI). Also the IP address for a wired connection is 192.168.51.1 and the bluetooth is 192.168.50.1. See if you can get anything through.
p.s. this thread is getting really messy maybe we should start a new one
