Incorrect KDn immediately following SNn commands

[werneta]

@com_poser, can you upload the musicxml for the MM11 piece that had this bug?

[werneta]

Got more information. It's when there's a KDn etc. that's at the start of a loop or superloop

This file shows how this can happen:

KD (100)[ [[ KDn]]3] ; Measure 1
[[ SN]]4 (100) ; Measure 2
r ; Measure 3

The problem is there's no KD at the start of the loop, so the snare gets retriggered at the end of measure .
