Thank you so much, for playing that, I've been playing with Yamaha keyboards since my childhood, and yes thay are really the best, and that one your playing is now driving me over the heels in love with its sound, since it's a new matle. And now I'm wontering what is the cause?
You can only record to an USB drive with SX600. Insert an USB drive to the keyboard, then press the USB Audio Player button. You will see the playback and recording options on the screen. Press button under the red recording icon to get to recording mode. Then when you’re ready, press the button again to record. You can press exit to get back to the main display screen while recording. Once you finish playing your song, you can press USB Audio Player button to get back to the player screen to stop your recording.
