Welcome to the forum!
What synth is playing the piano sound? If it's a general midi synth like Cakewalk TTS-1 then you're input midi channel (on the synth midi or instrument track) has to be set to 10.
It will suck big time, though, compared to the built in sounds of your TD-4, so I recommend using a dedicated software drum sampler (one that doesn't do piano). Isn't Session Drummer included with the SONAR demo?
