Hi There
There is a poll on Arranger World asking people to vote on the top 5 arranger features http://tinyurl.com/2k9mok and the MP3 player is still showing Zero. Perhaps this is why Korg make it an option. (There is little demand)
I must admit I seldom if ever use it on my Abacus, as a Wav file gives a much better sound. (Although in truth I do tend to steer clear of Audio backings)
Interesting

Bill
