When I render a sequence I am getting a gap in the sound. For example, the rendered WAV file will have the first 8 bars and then there will be silence for another 40 bars and then the sound picks up again. I've had this previously when the gap was only a few bars. Is this a known issue. it is not an issue with the patterns in the sequence as the same patterns play in other areas of the sequence.
