This would be very helpful to fix. In my situation, I want to programatically change the play rate of the sequence. I thought one way would be to have the animsequence specified in c++, so I can get at its original length and I could calculate a play rate from that. Then I’d feed that animsequence to a sequence player like you’re proposing. But it looks like this isn’t possible. And since this post is from 8/24/2014 and still unanswered, I guess it’s not going to be possible.
