If we must get this specific, 0.0154s is the fastest interval the protocol will recognize.  Anything shorter is rendered by Aurora as 0.0154s.
 
FYI... that is 1/65th of a second.  The human eye isn't even that fast... anything less than 0.02s might as well be rendered as on/off since it really doesn't matter anyway at those speeds.

Ah, alright, wasn't shure if it was hardware, software, or not valid.

I have two main places that I use really short ramps.
1. Think begining of "Wish Liszt" BaDummmBaDummm, although, those could be converted to ONs without a problem.
2. Think "Carol of The Bells" BummmDaDaBummm. That would be the hard one to fix because I have the roof ridges/eves/outline as the main notes so I would have had to add an off to every single marker.
 
So other than the short ramps in 15beta, did I miss anything else? I havn't seen anything else funny going on. Any idea when 15 will be out of beta?
Fine. You're so smart you rig up the lights.

You are right......0.05 does show up..........looks about equal to the shimmer command...Maybe is was 0.01 I was thinking....There was  a big discussion on PC about this..

0.05 is an acceptable ramp duration.

There is a firmware issue with 1.15 (beta) that D-Light is aware of where short duration ramps are concerned.  If you downgrade the controller firmware to 1.14 or 1.13 the problem might go away (but the old problems that those firmwares have will reappear).  I expect that once 1.15 is a release firmware this will be fixed, but only D-Light can answer that (I too am waiting BTW.. I have some 0.35 ramps that are glitching on 1.15 that render properly in earlier firmwares).

I'd think 0.05 is way too short for a fade....Heck, I think its too short for a full on command.Wink

I'd throw together a quick test sequences and try some different time lengths.....0.1  0.2  0.3 and so on until you get the look you want.  I'm pretty sure I dont use anything under 0.1....and that normally on either side of a solid ON command of 0.1 or longer.  You eyes just dont see something that fast.

I'm doing a number of quick fadeouts on my mini trees that don't register at all.
I'm on Aurora 1.0.2 with D-Light F/W 1.15 Beta.
My ramp is possibly .05
I'm probably going to need to go back though and switch the ramps to ONs, but, still how short can the ramp be?
I have a few places where the beat LongSrtSrtLong on the same channel, so if I don't use the ramp, I'll have to create an OFF event to add to each section.
