I dont think livestyler can play freeplay styles, same goes probably for varranger..

Dj, freeplay and session styles are of a different kind.. I know livestyler supports the standard SSF1 style format of Yamaha, but i guess for SFF2 you probably need to get Varanger [/quote]

vArranger is more money than I am willing to spend especially when I know that I won't probably use it as an arranger but more as a patch management.
I found this app that will convert SFF1 and SFF2 styles.
