LTP-HTP-AUTO

ok I'll try. It can get rather confusing but here goes.
LTP: Latest Takes Proirity. It puts the channel under your command. No matter what is playing back that channel will not change values until you make it do so. Use this function if you want to over ride say the color or gobo channels on the fly.
HTP: Highest Takes Priority. This I BELIEVE I'm not 100% sure but I believe HTP works kinda like what ever the highest value is for that channel that is what it will skip too. so if u had a scene playing back and you wanted to lower the DMX value you would not be able to use HTP cause the current scene playing would have the highest priority. Like i said i BELIEVE that is how HTP works chris is more than welcome to correct me if i am wrong or anybody. And auto is...... auto. it goes as programmed. Hope this helps.
Sincerely,

That is what I thought. So HTP is all good, but what if you want a to lower a DMX value, for example the dimmer channel?

I don't even have time to muck with the HTP/LTP issues, because frankly, the mouse is a crappy method of control, especially when it's a track pad and you've got your hands full with audio and video and all sort of other insansity to deal with, but this isn't an off-topic/side topic rant.

Using a MIDI controller to help with MyDMX(I'm looking to buy one!!), then HTP/LTP can become a bigger issue, because you'll want to take control of something on the fly. Or, if you're a dedicated and "non-distracted" lighting operator. Either way is good.

Look at how the term is stated: LTP: Lowest Takes Priority
HTP: Highest Takes Priority.

"Takes Priority"

I think the only issue might be as this appears to be a "global setting", you'd want to probably make the changes as applicable to what is going on.

But do understand my mindset on MyDMX, at least based on my implementation. I use MyDMX to first design, and granted, my designing ain't spectacular. It might win an award for "Crappiest lighting design in a small event application", but it does get the job done. Is that the fault of MyDMX? Sure ain't. It's MY issue, I am a sound guy, not a lighting guy. After my basic designing and organization, I simply use MyDMX for scene triggerig, no mods. It isn't perfect how I do things, but it is quick and gets the job done.

It is also entirely possible that in "user" mode, HTP and LTP do not function. user mode seems strictly scene based, but they do show the faders, so who knows. There must be a reason behind that.

Honestly, I don't have a real-world application for those features yet, but I can certainly see a necessity for such features. Maybe one day when I get a lighting tech, that person can dink with it.
