If your data doesn't have custom waveforms, user curves, user microtuning, etc - and if you only have a handful of Performances to transfer - then Soundmondo is a good way. If you do use user curves/custom waveforms - then you may still use Soundmondo - but clean up those custom portions after-the-fact by hand. If you're dealing with too many Performances - Soundmondo may become cumbersome.

Reference manual shows user/library files with Montage format (X7U/X7L) only under the "Load" section and not under "Save/Store". So you cannot apparently save a Montage-format user or library file.

Software assist is probably a way. JM Tools as an option. I don't have these so I cannot speak to the merits.

I create a backup file in ModX, and then I change the file type to .X7A. Yamaha montage load the file correctly 🙂

Potentially dangerous as the products diverge. And there may be corner cases even today where something doesn't land right when doing this. Not recommended.
