Autotune wasn't a new technology when T-Pain started using it, but he certainly became the audio plug-in's biggest advocate. And who could blame him? He might have sounded like a robot, but at least that robot made good songs.

Then Jay-Z's "Death of Autotune" put the kibosh on autotune and it fell out of favor with the rap community. Until last year, when Future seemingly revived it.

Well, it seems T-Pain might be a fan of Future, but he's not exactly a fan of how Future has gone about using a technology he once rode to fame and enormous riches.

"I don't think Future gets the technology," he told Big Regg of Hot 93.7 in Hartford, CT during an interview. "I don't think he understands how it actually works. I think he's thinking you just turn it on, and it happens.

Pain acknowledged that Future -- like most people -- is probably not as familiar with the technology as he could be.

"A lot of people don't sing with it, they just sing and put it on after, which is a terrible mistake," he said. "There's a lot of stuff you've gotta know about Auto-Tune before you can start using it, because it's the hot thing to do. But Future's still great, he's doing his thing."
