Record at the same time as an audio file is played back

[drvenom]

I have a question, see if you can work it out for me.
I record a lot in audio format (mp3 or wav), and when I see that the PSR sx900 has 2 usb inputs, my doubt was that if at the same time I play the recorded audio file, I can touch the keyboard and that everything is recorded together.
It would be a very interesting option if I could, even though I haven't made it.

You can try to use the audio in on the keyboard to mix both together
The best with a external mp3 player

Yes, I already did that in my previous psr.
He used the aux with a player and played at the same time and thus added something to the song.
The interesting thing would be to be able to do it directly from the 2 pendrives that can be installed.
