As Divemaster said, there is really nothing that MUSIC FINDER does which you can't do with PLAYLIST.
Like I have stated a couple times already here on the forum, a registration can't do the most important stuff that an actual gigging player uses (or should be using) with regards to the MF.
Using the PLAYLIST is fine if you are sitting at home and entertaining yourself. You have all the time in the world to hunt for a song in your list and then the lead sheet. The MF is for use during a live show.
Well, for just one thing .... you can't embed a CODE into the Playlist and have 16 songs that you want to do in your first set appear.
Two ... as already pointed out in this thread, you can not scroll quickly through the list of your 450+ songs to find the song you were just requested to play on the fly. Keep in mind the MF jumps by letter groups A, B, C, D, ...Z (not one song at a time).
Three .. You have found the REQUESTED song style using the MF, but where is the LEAD SHEET? You go to the EDIT tab of the MF and there you can read the CODE you used to organize your songs by SET NUMBER. You grab your song book of 450+ lead sheets and flip to set #18 and quickly flip through 16 sheets to get your music. SIMPLE and fast.
Four.... MF can be coded to show what key you need to transpose into to sing the song.
Five ... the MF calls up the Intro to start the song in and can instantly advance to the first Main to be played. The Playlist might be able to do this but as a performing singer this would take one more slot in the registration that your mic preset up is using for the song. You will have to also set everyone of your 450+ registrations with the INTRO and 5 to 6 mic settings you will be using for that song.
That is insane to have to do that.
The biggest mistake Yamaha made was dropping the MF for the Playlist misfunction, if you are performing LIVE.
