First, I think Resolume it totally amazing work! I've been doing a lot of experimenting using Ableton and Actionscript to drive imagery and it's blowing my mind. Hope to have some things in my performance set soon.
However, what I've discovered is that the Ableton sync clock wavers, and so getting completely reliable timing in Resolume is very difficult. In Resolume, the flat image doing a repeat scale, will occasionally miss, or reset at an awkward time. I'm doing some fairly minimal work so it becomes a problem. It appears that that is actually happening in your demo.
I don't think it's a Resolume issue actually. I tried using an external midi clock to drive both Ableton and Resolume, and Resolume responds very well to that, but if Ableton is in slave mode, it doesn't really do what I'm looking for. I've read about products doing something to "smooth out" the Ableton sync clock?
If I just turn off Resolume's sync clock, and fire events directly from the Ableton timeline, then things really start to be tight. But what I'm looking for is some way to keep it in sync live.
