Tam Tam sound is choked

My Tam Tam sound is choked (stopped too soon) in Halion Sonic SE2. It sounds right for about 1/2 second, then stops. It is a whole note, so it should last the 4 beats at least. I have loaded the HSO Tam Tam Percussion map on that channel. I have tried Tam Tam Combi Key and Tam Tam Combi KS, same problem on both. Thanks for your help!

Just a thought, but does adding the L.V. (Let vibrate) tie help in this situation?

It’s fine when I checked it - it lasts for the length of the note and if you tie it to another note it’ll last longer. L.V. ties are only for display I believe.
