I somehow lost left midi signal. Haven't disconnected anything. When I playback tracks or play live on anything midi, I only get a right signal on my Tascam US-144.
This is happening on all my tracks.

This isn't a MIDI problem because MIDI is a digital signal, there is no left/right MIDI signal, just a stream of numbers.
So it sounds like another problem with your soundcard. Between this problem and the last one you had, it really sounds like you either need to look for a new soundcard or better drivers for your current card.
You could try switching the Driver Mode in SONAR again, but I don't know if if that will work.
