I would think there are 2 possibilities.
1. there could be an intermittent MIDI connection. This could be the cables, the sockets these plug into or the interface.
2. you may have a problem with the key/hammer sensors. If you try to record again, put the piano into record mode as well. If the piano plays the recording back OK, it's your connections/interface, if the playback on the piano is intermittent, you have a problem with your sensors.
