Hi - I have beeen using the same version of Chuck (1.3.5.2-beta-2) on OSX Lion (10.7.5) for over a year, without any changes or problems. However something strange happened, and I'm stuck: All versions of my Chuck-based software stopped working with my WX-5 (including those that I had frozen and worked fine) I tried the WX-5 with GB+Wivi, and it works fine, so I know the hardware is ok, and OSX is passing the midi events to the applications. As one more check, I ran "MIDI Monitor.app", and it reports correctly all the Note on/off and CC events I'm sending with the WX-5. So I tried MiniAudicle->File->examples->gomidi. It opens succesfully Midi dev 0, and then it blocks forever at min.recv(msg) ... Can anybody give me a suggestion of what could make Chuck not see the Midi events, or what I can try next? Thanks! Daniel
