Are you using an Audio or MIDI interface (e.g., iRig MIDI) or do you connect your Piano via USB? So what cables are involved?
What do you mean with recording sounds? Did you record a MIDI-event and sent it to your piano? In this case you should be able to switch the sound on our piano and hear the difference on your headphones?
So please provide us some clarifications about your setup that we can help.
