I was checking through your post, and input echo is enabled.
 
I cant set the input for the audio track to the channel receiving the keyboard audio, it just sefaults to 'None' after trying to change it, so the audio isnt being sent to an audio track.

So you get the list of available audio inputs in the Input drop-down, but it reverts to None after you select one? Not sure what would cause that right offhand. Is it a USB interface? If so, maybe reboot your PC and make sure the interface is powered up first.

I tried that as well as reinstalling X3 producer and my keyboards USB drivers, but I still cant change the audio track input to the USB piano :X

Derp I got it working, I hadnt selected the input through the microphone in.

I don't understand most of the answers in this thread. It looks to me like "Why make it simple when you can make it complicated".
 
To the OP I would install the Yamaha USB MIDI driver for your "piano" (if not already done), go to MIDI devices and make sure they're activated; there you can move the MIDI output driver of your keyboard to top, so it will be the #1 MIDI device in the track MIDI output list.
 
From there, go back to track view, insert a MIDI track, select your Yamaha as the MIDI input device, arm track for recording and "record".
 
Once the recording is completed, hit "play" and it should play on your Yamaha if you moved the output MIDI device to top as said above. If you didn't move it to top in MIDI devices, simply select the correct output device in the track MIDI out list.
 
From Vab original question, I don't see any reasons to have an audio track, it should work with only MIDI tracks (for what he asked).

The question was: "Is it possible to play and record the voices on my piano... "
 
You can't record (or monitor through SONAR) the piano's "voice" without an audio track.

The question in the title of Vab's post wasn't the same than the post itself, I've answered to the POST, not to the title and I stand by my reply, for recording and editing using the hardware synth sounds only MIDI is necessary, no audio tracks are needed.

I understand that at some point you have to record the output of the synth into an audio track but it's before the mixing not before all editing is over.

Bottom line is that I and others gave him the standard operating procedure for working with hardware synths, and he got it working just fine. The thread only came back to life a month later because of a configuration issue.
