Here is an audio example of the problem.
As you can hear the loop looses a portion of my initial loop over a short period of time. It does not occur on the first loop. These are only rough examples and are not perfect but you can clearly hear the error. Although this does not happen in every instance, it does seem to occur more often than not. This renders the unit unreliable.
I look forwards to your thought and I am quite happy to submit more examples and to work with you in any necessary way in order to rectify the problem.
