Yamaha DTXpress/DTXplorer/DTXtreme

I have had the same problem. Here's a test that may help us: For
anyone who has the DTXPRESSIII , go to the "2nd line" tune and trying
playing a crash and then playing a beat of your choice right after
that using at least the snare / kick and hi hat or ride. does the
cymbal "choke" early?. I am convinced its a software issue because
when i stop the song and play the same kit - there are no problems.
I've noticed this on other songs too.
