Control 2 steps differently in a chaser.

Hello,
I want to control a fog machine. I would like to be able to change the ejection time and the non-ejection time differently.
This is not possible with a chaser or a sequencer.

Or very simply:

A fog machine widget would be nice :D
With: - ejection time
- non-ejection time
- fog volume
- fan speed

Is this possible in a soon coming version?

Hi this all sounds possible already, what DMX attributes is your fog machine using?

What I always use is a chaser with asymmetrical timing.
Before show time, I define the utmost fog a venue can have. So, basically, create a mist—way too much for the venue. Remember that ventilation and open (closed) doors may influence this behaviour.
Now, this said, I have the 'output fog' setting fixed in a scene. In general, I set the fan speed to a value that will reach the other side of the stage and get an even mist.

With the help of a zero-fog scene, I have a chaser with two steps. The off-scene and the 'output fog'-scene. Both share the hold at the same time.
With the help of a Speed Dial widget—this is what you are after—I can dynamically set the amount of fog I'm producing, whether slow pulses or fast pulses. The fan speed stays constant.

A completely normal fog machine or hazer with 2 channels:
1. Fan Speed slow to fast
2. Fog Volume

Could you perhaps create a little example .qxw for me?

I am currently controlling the fog machine with the controller in the picture.
I would also prefer to control the fog machine with QLC+.

Can you share the make & model of your fogger?

Unless I'm misunderstanding what you're trying to do, since you can control the fan speed and fog output separately, I don't really see the problem.

If I want to have a low fog output with a high fan speed, I can create a Scene with the fan set to 255 and the fog set to 32. If I need the fan to run longer than the fog, I can create another Scene with the fan at 255 and the fog at 0. Put one Scene after the other in a Chase and set the Fade In, Fade Out and Duration of each step. Each individual Scene can be used and reused numerous times within a Chase.

You can create any number of Scenes with various Fan and Output levels. I've used foggers in this manner for years.
