Q Light Controller+

Hi all,

trying to control the speed of my EFX scenes using a VC speed widget controlled by a midi fader. Only problem is when i adjust them, the lights shake and move really quickly (not ideal when i am trying to slow them down for effect). I'm assuming this is caused by QLC+ wants to restart the EFX as soon as i change the speed, thus causing the values to change rapidly.

Hi,

I've planned to fix this, but got distracted in the meantime. The formula to compute the position has to be changed if we want smooth speed changes. The code in question is EFXFixture::nextStep().

Hiya Jano,

Just tested the same thing in QLC original (Setup an EFX, assign movement to a bus, then assign a VC slider to that bus) and noticed changing speed is totally transparent. The movement keeps playing, but just dynamically slows down. I wonder what they do differently.

Yes, it seems that the change happened when Heikki moved from buses to individual timings. This is the change: https://sourceforge.net/p/qlc/code/2532/

I will (partially?) revert the change.

Joe,

I've (hopefully) fixed this issue in git. It'd be great if you can test it...
