ok I should clarify before I get killed, AT mentioned in their statement that they're fine with hybrid-DAW productions. Fully-produced tracks made in another DAW are still, I believe, against the sample upload TOS and is generally looked down upon.
it's a bit hot topic for a lot of people. AT themselves removed the 30 second upload limit because (I'm pretty sure) they want stuff like this to happen, to be more of a music sharing platform, but a lot of people only want AT-made music to be released on AT, which also makes sense because of chart eligibility. I'd say try to make most of the music you publish here AT-made, maybe export stems from FL if you need them, and that should get people off your tail
