autobeam issue in split measures
if there is a measure that is split by a bar line (such as a open master repeat) and any beamed notes are after the split and before the start of the next measure, NWC2 does not autobeam the beamed notes. this happens with 8th, 16th, 32nd, 64th (i didn't check it beyond that). it also doesn't autobeam beamed pickup notes unless they are preceded by enough rests to constitute a full measure in accordance with the time signature.
