My Yamaha YPT-310 is connected via USB MIDI to my laptop running Cubase 5. The software correctly reads the connection to my MIDI keyboard (see attached image). However, when I try using my keyboard to control creating notes on a MIDI track, nothing happens! That is, hitting C on my keyboard results in no sound from my VST. However, hitting C on the piano roll within the VST results in expected playback. I had successfully connected my keyboard to Cubase 5 before, but this was about 1 year or 2 ago. I cannot figure out how to get the setup to work. Looking forward to your replies.
