Good point about the controller, PB, etc. data. If you don't watch out, it can use up gobs of memory in a hurry.

Rather than data thin, I think probably he's in a position just to use . . . ERASE That is, he just needs to erase *all* the controller data on *all* the tracks where such data has been *inadvertently* entered. I do that periodically during every recording session. Or, as you say, turn it off entirely.

As for patterns: "Could I create patterns (sections of a song) and link them together as a work-around for memory limitation? I'm not sure if you can link patterns together that are not part of the same song though"

I use patterns all the time, all over my songs for precisely this reason: If something repeats, the pattern message takes up much less memory than pasting the whole measure over again.

Yes, you can paste patterns together from different songs . . . sorta. You have to load them individually from disk from your different songs and then string them together (with pattern call messages) in the internal song. You must then save that internal song + the imported patterns into a single song.

Is any of this helping? You know, if you're still having trouble, you could probably send your .svq file to some of us on the forum here to have a look at.

Anyway, good luck. You should have plenty of room in the XP50 for what you're trying to do.
