Loop replacement on the fly

[Falconex]

Hello

Does anyone know about the existence of the plug, which I point a folder with my samples (eg beat loops in wave or aiff format) and I can hear the sample simultaneously and in synchronized bpm with the rest of the song ? (on the fly)

My friend who uses Acid, flipped samples on the fly and heard as they go throughout the song. It worked smoothly and quickly.
I would like to have the opportunity in Logic Pro X


Thanks for ideas.

PS> I know it's the way in EXS24 but it's complicated, and i'm looking for something else.
