I can hear audio but not MIDI

My first thought is that MIDI is not audio, so no one can hear it. MIDI is a set of machine instructions to make an instrument (outboard synth or softsynth program in the computer) play music. So obviously we do not know what you are trying to do. If you want help, you will need to spend some time and effort explaining your problem. Most of the time this question comes from someone who does not have his MIDI tracks set up properly to feed their data into a softsynth.

OK, so now we know you have at least two pieces of equipment (mixer and outboard synth) that we would not have guessed from the OP. The problem remains that it is not clear how they are connected and what you are trying to accomplish. Since the Roland XP-80 is a MIDI keyboard controller, a MIDI controlled sound module and a MIDI sequencer in its own right there are a lot of possibilities. Is it that you want an already recorded MIDI track in Sonar to control the Roland XP-80 sound module via a midi connection (how is that connection established?) and then to record the audio output from the XP-80 back into Sonar? 

Just to be clear, you are never going to be able to hear a MIDI track while it is still MIDI only. The sound has to come from something else that is controlled by the MIDI track. I think you are saying you want the MIDI track to make the XP-80 play audio. But how does it get to your speakers.
 
If I have this right (and I am not sure that I do) you are using the Uno as the output from the Sonar MIDI track, the MIDI out from the Uno is connected to the MIDI in of the XP-80, the audio outs from the XP-80 are going into a mixer ... and that is as far as I can guess. Somehow the audio out from the mixer channels that the XP-80 is feeding has to be routed to your speakers. It sounds like you may have your speakers as output from Sonar, but not have the mixer output running directly to the speakers. If that is the case you would not expect to hear anything from the speakers (via Sonar's main outs, through an as yet unspecified audio interface) unless you send the XP-80 audio signal out from the mixer in to the input of a Sonar audio track. At that point, Sonar can record the audio in its audio track and also echo it out to the Sonar main outs.
 
Can you hear the output you want from the headphone jack of the XP-80?
If you connect your speakers directly to the output from the channels on your mixer that are taking the XP-80 as input can you hear it?

Also to be clear, if MIDI is being routed to an outboard synth, the AUDIO made by that synth is what needs to be recorded (not the MIDI out of the synth).

By the way, does anybody know why Cakewalk has been closed for the last week. I'm in pretty desperate need of technical support  (for more than just this).

So you don't have an audio interface?
I think what everyone here is trying to tell you is your trying to hear sound over your MIDI connection. You need the audio connection from the Roland

 I am certainly far from knowledgeable  and probably shouldn't chime in here but I has a similar problem a month or two ago. This is may not be what you are seeking as a solution ... but who knows??? 

• Select Insert SoftSynth
  • from the main pull down menu
• Select Direct X
• Select Cakewalk TTS-1

Your midi output track needs to show up on your Soft Synth track as Cakewalk TTS-1 so that your midi instructions are implemented.  If you can hear the midi doing its thing then you'll have an inkling as to why you are otherwise getting no Midi output.  From there it's a matter of playing around with the parameters of the Cakewalk TTS-1 soft synth (or another that you may select) to get the sound you want to hear!
 
 
 
 
 

Please pay careful attention to the steps outlined by TLW above. This will solve your problem.
