A question for anyone that is using Holidaycoro for lighting...what's the fastest rate you've been able to get your controller to respond to DMX signals? I have a few sequences that I set to 150ms, and that seems to be the fastest setting I can get it to respond to without skipping sequences.

I'm wondering if this is an issue with the controller, the rate at with Artemis can output signals, or possibly my DMX-USB interface creating this limitation. I have a feeling that my controller may be overwhelmed, because I tend to have a lot going on at any given time. I really wanted to set the sequences a little faster, especially for shield/weapon impacts, but setting it below 150 seems to not give the controller time to react.

Just curious what anyone else's experience has been.

Are you talking about the digital controller? or the USB-DMX convertor?  I haven't noticed much flicker in the lights I've got, but I've never done any stress testing either.

That's the part I'm not sure about (which device is causing the problem). I rarely get a flicker, what's happening is this:

- Ship takes impact from NPC beam.
- Triggers DMX command that should be 3 (or in my case 5) flashes
- Lights only show 3 of the 5 flashes at faster speeds, all 5 at slower speeds

It's as if the controller (from Holidaycoro) can't keep up with the commands it's being sent.

It could also be Artemis itself - Dave Thaler updated the DMX portion of the unofficial wiki with the info that Artemis only makes calls to D2XX.dll ~ 30 times per second, although that should be fast enough to not notice much flicker.  How long are your fast flashes versus slow?

In the original DMX commands file, the SOMETHING_HITS_PLAYER command used alternating on/off flashes at 60ms intervals. There are 3 instances of white lights in that sequence. If I run it that fast, my consoles usually end up just missing one or more flashes in the cycle. So, I may see 1, or possibly 2, with it skipping the one in the middle. I increased to 100ms, and that sometimes works, but it's inconsistent. One time I see all 3 flashes, others it's just 1 or 2. Bumping it up to 150ms seems to have fixed it. But, it's less of a strobe/flicker effect now, its more like a fast flash. It works fine like that, but it doesn't have the "short circuited" console look any longer. To compensate, I've changed those damage indicators to do 5 flashes, at 150ms.
