Odd Problem with Boom

[DonaldM]

Here's a little odd problem that surfaced last night with Boom. I had Boom instatitated on an instrument track, and then using the pencil tool, drew in the places where I wanted the drum pattern to play and which one. That all worked fine as where it began, but the pattern continued to play even after the music had moved on past where I had the play notes. In other words, it'll turn on but not off, even when there is no longer a midi note there telling it to play the pattern.

Any ideas?

Thanks
