I have the M Audio 02 MIDI controller and am using it with the Tascam US 122L. I have a problem in what i should i do with the MIDI output. The MIDI controller doesn't have a MIDI output, if i direct the MIDI output through my computer i can hear it but the audio output comes through the tascam so i get one and not the other. When i direct it to the tascam it doesn't sound? Help?
