There's a delay when I use Hot Cues and Reloop. Why?

The Quantize function in your DJ application might be turned on. If so, the cue/reloop starts at the nearest beat position when you press the button. If you want to set the cue/reloop point at the position exactly when you press the button, turn off the Quantize function.
