Unintended consequences with Chauvet Geyser RGB

Two queries related to the fixture description for the Chauvet Geyser RGB in the most recent library updates.

The Geyser is an effects smoke machine - it has a set of LEDs combined with a vertical smoke machine - our use is in place of pyros for a pantomime where we are using several with a Ion running 2.0.1 and a very recent library update (I think its revision 30 or so).  Fixture info at http://www.chauvetlighting.co.uk/geyser-rgb.html

 

If AutoMark mode is set on the Ion, then any cue which brings up the LEDs and Fog together has the Fog change pushed back into the previous cue, with hilarious or embarrassing (or both) consequences.  Is it possible to change this behaviour so that the smoke parameter is not marked like this?  Currently running without AutoMark :-)

 

Also, would it be possible for that fixture description to be changed so that the default value for Color Mixing is zero (ie you get the output colour you expect) rather than 255 (it flashes through a range of colours around the selected colour)?  This seems like a very strange choice for a default value.

    Which version of the library are you using?

    In 9.1.0 build 32 the "Color Mix" attribute, DMX offset 5 is already homed to 0.
    Do you mean another attribute, or do you have a different version?

    Having checked my downloads folder it was 9.1.0 build 30 that was put onto the Ion - unfortunately I am not near the desk at present.

    The specific attribute that I think should default to 0 is DMX Offset 6 - what Chauvet call "Auto Speed" and on the Ion fixture definition has a longish name (sorry to be vague).  If zero this causes the RGB values to be used as a steady illumination colour, but at higher values causes the colour to cycle around in some slightly obscure way.

    Thanks, yes DMX offset 6 is currently defaulting to 255.

    We had thought this attribute only had any effect if offset 5 was non-zero, clearly this is not the case and we'll need to change it.

    In practice I see very little visible effect from Color Mix (DMX offset 5) although I have not spent a lot of time playing with it, and personally I am not particularly thrilled by the effect of DMX offset 6 :-)

    Of course there is always the possibility of things working differently with other revisions of the Geyser firmware - however all 3 of the units we have on hire this week behave the same way, which is that DMX offset 6 set to pretty much anything above 0 gives a lighting effect which sequences the R, G & B LEDs rather than blends them.   We have been leaving the Color Mix set way down - normally just defaulted.
