Hi Fred,
I now understand how you work on your keyboard so it now makes sense to me. You just work in a different way from the way I work.
For most of the time I play, I don't use songs at all and the one that cluttered up my registrations, I've never used because I have never played that song.
So it makes sense that you would like the songs to remain in memory and that's fine but there must be many, like me, who don't want to use a song AND,
The song I had stuck in my registrations was primed to run with Sync Start and it kept re-appearing after the registrations had been cleared.
I obviously don't want a different style of music starting up whilst I am playing something else. I have never found out why this happened.
Yamaha change the OS sometimes anyway and there have been 3 updates whilst I have had my Genos.
They could allow us to choose whether to keep songs in memory or clear them and I would choose to clear them but that would not affect people like yourself.
Your solutions 1, 2, 3 and 4 are not a suitable way to deal with the problem because
1 I wouldn't need to load a slow waltz if the damned registrations didn't keep loading this unwanted song up.
2 I can't ignore it because that would not stop it from Sync Starting,
3 would be extra messing around when playing gigs when all I want to do is load a Registration and play.
4 would be the same as 3 and mean messing around again whilst you are sat in front of a waiting audience.
The way this song spread through many of my registrations shows that there must be a bug in the OS which I have somehow managed to trigger.
I have owned 3 Yamaha's, 3 Technics, 3 Roland's, 2 Ketron's and a Gem keyboard and have never had problems like this before.
It does not speak highly for Yamaha if people have to find workarounds for something which should not happen anyway.
The registrations I have worked on have been reset once again to load and save Audio files but not Midi files and the problem file was Midi, in Audio A player,
so I am waiting now to see how long I will be trouble free.
