For the home user the built in audio recorders are perfect...simple, effective easy to use.

Of course, the pros will want more than simple and they can find that in a software sequencer....but the majority of arranger buyers aren't pros.

Thee home user/hobbyist is usually happy enough to make a WAV recording that they can burn to CD or turn into an MP3 so they can e-mail it to their friends.

Yamaha's audio to USB is so cooool!
