Hello J.Larry
All the demos I have seen about IDC have included a Midi demo of the song/style, which you can listen to on the site direct though you’re Yamaha before you decide to purchase.
Follow this link http://www.musiciansroom.net/Videos/default.aspx and choose the PSR 3000 Demo, you will find IDC towards the end of the Video.
Hope this helps

Bill
