Loop Start and End

A sample, unlike the cycles of an oscillator for example, is a finite quantity. There is a sample start and end. To get samples to play for as long as you press down the keys on your keyboard, they need to be looped.

For this to work properly, you have to first set up two loop points which determine the part of the sample that will be looped.

The instrument samples in the sound banks included with Reason are already looped. The same will be true for most commercial sample libraries. However, if you need to, you can use these controls to adjust the looping.

The size and position of the loop - in the sample - is determined by two parameters, Loop Start (the beginning of the loop) and Loop End (the end point of the loop).

The NN-XT then keeps repeating the section between the Loop Start and Loop end until the sound has decayed to silence.
