Start/Stop Sampler

Stop sampler playback on Engine OS. Allow Djs to stop a sample sound/song being triggered by the sampler.

Serato Dj has the ability to start and stop a sample that is triggered.

Please use the proper format by filling out the prompts supplied in the feature request.

Iā€™m moving this out of the feature request section anyway because the ability to stop the sampler playback can already be accomplished by pressing the shift and the playing pad.
