Hi,
There may be some misunderstanding but the audio recorder is not another way to store sequences to reload into the keyboard.
If you wish to save the performance so you can make your own CD's or send files via the net then follow as below

1 create you performance in the sequencer in the piano.
2 connect computer via USB ans start Audio recorder
3 Start recorder and start the sequencer playback,check the levels on the meters adjust as required, when correct save song in the format you require ie:-WAV. MP3. etc to your hard drive. Then import to your favorite CD burn program, make up your play list, burn and hay presto!!! you have now made your first CD!!!! now design your CD label, sleeve
and of to the record store (sorry Music store showing my age) and as they say watch the millions roll on in(Ha1 Ha!) All the best John.
