Play/Play Start(2000 classic)

I've seen videos on YouTube where people have a beat loaded up into the mpc and they hit play start I guess over and over to replay the beat on the one and then they let it play after a few presses. Similar to how alot of old 90s beats would start out. They use it as like an intro if they're just showing a beat in their video. I'm wondering if the 2000 classic just isn't able to do that or if im just not doing something right. Let me know boyz, peace.
