I'm using version 5.5 for Windows. Everything was working fine, but then the virtual MIDI keyboard in the evironment quit showing input as did the monitor. The master controller is no longer sending MIDI into Logic but Soundiver is monitoring it fine. I've checked all the settings under options for MIDI and none of them have changed. What might I have done or set to inhibit the MIDI data from reaching Logic. I have never had this problem arise before and I'm quit at a loss here for ideas. I've been using Logic for 8 years now. I feel really quite stupid.
