Control of hazer timing + channels from virtual console

[davidf]

I just can't figure out a way to do this-

I have a generic 2 channel hazer (fan, output). On the virual console, I'd like to have control over the interval and duration that the hazer will beoome 'active', and also to have control of both fan and output levels during this phase. When the hazer is 'idle', the fan and output levels need both to be 0. The sequence needs to repeat indefinitely

The closest I've managed is using an 'active' and 'idle' scene within a chaser, and which runs as a speed dial function. This isn't ideal as this gives me a fixed 50% duty cycle between active and idle states and the channel slider settings get overwritten by the scenes in accordance with the channel types (speed/intensity).

I'd be grateful if someone could suggest how this might be approached

Many thanks

An interesting puzzle...

Attached is a solution I thought of but it may not be the neatest method.

Being able to control the fan and faze independently is what complicates the situation.

In the end I used two chasers (with the same timings) and then sub-masters (version 1) or a slider (version 2). A script is then used to make sure they start together.

In version 1, I did notice a weird bug (I am using a mac so you might see different) where the sub-masters didn't seem to take effect immediately but if you press stop or pause in the cuelists and then restart the process it seemed to work.

So I created version 2. It is a bit simpler. The sliders control the chaser output.

Wow- thanks for this, very ingenious! Although I can't help feeling surprised/disappointed that such a simple requirement cannot more easily be realised in QLC

But once again, thank you for passing this on, very useful!

No worries.

I wouldn't be too disappointed. There are so many different user requirements for lighting these days and QLC+ does an amazing job at covering most of them, even if the solutions can sometimes be a bit unusual.

I am very much an amateur when it comes to lighting but like experimenting. My experience is mostly high school musicals. For my faze, I just have a solo frame with off, high, medium and low buttons running 'haze scenes' and then adjust it when necessary. Our theatre is quite small and the haze is easily affected by open doors etc so I can't really just set and forget.

Looks like the issue with a slider master and cue lists has been resolved so Version 1 above will work in future versions..

Did a build of the latest version and can confirm that fix works.

Hello,

Why not just using a collection which contains both chasers ?
They will start synchronous and it's really more simple than with scripts.

Moreover, with some loopback, I solved the problem where cycle is always 50% on/off.

In the attached example you can choose off and on duration with 2 separates faders.
