it keeps turning off by itself when i try and export a long sample from the internal a-b banks. but works fine when i export from card banks, weird.

t(smpl) < t(rmn):2

just a guess:
when your sample is longer than 50% of the remaining time on a+b the export won't work.

could be complete bs, but i had similar issues with smaller cf-cards, that's when i came up with that formula...
give it a shot and let me know!

yeah that seems like te problem, thanks
