hm currently it’s like this:
if you drag more than one file at a time, the pads are not active at all.
An option pops up, asking if you want to load the files to the project or just the +drive.
you confirm your choice and it transfers them one by one until they’re all done.
I think this is logical - doesn’t make a lot of sense dragging multiple samples to one pad at one time.
However you asked earlier about being able to queue up transfers to pads, this would be fun but is a bit more involved, requires a partial UI/logical rewrite. Not gonna happen in the upcoming release at least.
