Q Light Controller+

Setting: House of Worship

Basic Configuration: All sections of a Sunday service are pre-programmed as functions (scenes). Volunteers either touch the corresponding scene on the iPad as the service progresses, or trigger the scene via ProPresenter's MIDI module, so virtually zero knowledge of QLC+ is required.

We have house lights on a Leviton 8 channel dimmer (7 tracks of an LED track lighting layout in a commercial warehouse architecture.)
We have a single warm white spot that lights up the cross on a wall.

Question

If at any time during a service, we want to manually adjust the levels of either the house or the cross, we're limited to a range above the maximum setting of the current function (scene) as a result of HTP. So, if while playing a video, the house lights are faded to 20% by the function, we can manually increase the house lights to 100% and see a noticeable difference. But, if the house lights are at 80% and we want to bring them to 60%, we're limited due to HTP, unless we kill the function and manually control everything for that period of time.

In any scenario, what are the fundamental challenges of using LTP, and does LTP give us the ability to adjust a channel on the fly, overriding the function's settings temporarily?

Only possibility to lower that value is to use submasters.

LTP mode will work but you have to understand that if there is a normal function running and you are interrupting it by something - your light will follow this, but afterwards when you stop the interruption, nothing guarantees that the normal function will regain control again (unless you fire it again).
Even more worse will be the cross fade timing issues. Cross fades will be very noticeable if you overrule the normal function. You will stream all kind of Latest information and your lights will respond accordingly.

Test it: copy your project; change all your dimmers to LTP and have it a spin...

Another idea:

You can add another fader for your cross light and/or house lights, but put them in level mode and let them control the respective channels.

On the "level mode" tab there's a checkbox "Monitor the selected channels and update the slider level". If you tick that box, a strip showing the monitored level and a button with a cross drawn to it appear, and this slider starts to act similar to those of the simple desk.

I.e. the slider follows the function values, and as soon as you touch the slider it takes priority and that cross button shows red colour until you click it (which releases the override)...

I've even made a small project to test my proposed solution, but forgot to append it to my previous post, so here it is...
