Music volume control

debbio · Fri May 15, 2015 8:02 am

Hi Massimo! What about a music volume definition in fixture properties of a music file? So that it should be possible to set different music's volume level for every track..
Other question: when will be video playback available on Linux systems?

Thank you

Huh ?? Don't understand what you mean. Please explain and give more details of what you are doing and what you want to achieve.

Track of what ? Of a Show ? It is already possible by right clicking on a virtual console button attached to a Show

It's already there. Just build QLC+ on Qt5 yourself: https://github.com/mcallegari/qlcplus/w ... -build-Qt5

Sorry I mean in function properties.. Let me explain:
In functions tab I add a track that in virtual console I link to a button so that when I press that button the track starts.. And this works perfectly! But.. In case I have different tracks that have all different volumes (one is a soundtrack during an actor speech, another is the final track and so on) I need to move the volume cursor on the fisical audio mixer to achieve the correct volume for every track.. What about if when I see the properties of a track in function tab I could set also the volume?

Fantastic for video support!

There is no "track" in the Functions tab. Please use the appropriate terminology otherwise we can't help/understand.

By "track" do you mean an "audio" function ?
If so, the virtual console button widget has a "startup intesity" control property, which in the audio case means the volume.
Otherwise you can attach an audio function to a slider in playback mode and adjust the volume (intensity) whenever you need to.

OK I didn't know this solution

But if I create a chaser with all my audio files and in virtual console a cue list linked to the audio chaser, the volume is always 100%.. This is why I think it could be better to have a volume definition for every single audio file in Function tab..

Then:
1- create a frame
2- add a cue list to the frame and attach the chaser to it
3- add a slider in submaster mode to the frame

The submaster will adjust the volume of the current audio file played by the cue list

Mmm the slider in submaster mode doesn't change anything.. Am I wrong? I simply add a slider into a frame with the cue list

Edit: the submaster mode works without problems with buttons but not with a cue list

Before suggesting it I tried it...
Make sure the slider is INSIDE the frame. Maybe you added it and didn't realize it doesn't belong to the frame.
Try to drag it out of the frame. If it goes out, then it means it's not part of the frame, but just above it.

It's inside the frame..

Oh, wait, on which operating system are you ?

I tested on Linux + Qt5 + QLC+ GIT and it worked

By the way, Cue lists have also intensity control sliders for the crossfade functionality.
Just click on the bottom-left button and a panel will open on the left side.
With those sliders you can control the intensity of the running function. They should control the volume of the audio files in your case.
Please let me know if that works in case

I've tried on my archlinux and on a lubuntu desktop with version 4.8.5... The submaster slider gives me no problem with single buttons for each track.. But it doesn't work with cue list...
Yes I know the crossfader of the cue list but I can't prepare the level before the track starts.. In the moment I give for example 1% the track already starts

Can you try with 4.8.5?

I can, but there's been no changes to the audio code (or submaster) since 4.8.5 was released.
Most likely this is related to Qt4/Qt5 difference.
I will implement the startup volume feature for audio functions as soon as I have some time.

In the meantime, if you can, please try to build on Qt5 (so you'll have video support as well)

[EDIT] FYI I just tried on Qt4 with Submaster+Cue list and it works as expected

debbio · Sun May 17, 2015 8:38 am

OK I'll try

Thank you so much!

Mmm strange, can you send me the file.? To build the qt5 version have I to download the 4.8.5 package and than build with qt5 dependencies? Or there is another package?

Edit: also on a windows PC same problem... I think I'm not doing the correct procedure... Also with scene function the submaster works if I link a single button to a single scene.. But if I put a cue list it doesn't change

Hi,

This has been fixed by

https://github.com/mcallegari/qlcplus/c ... 1a4e6049c8

So it won't work with QLC+4.8.5, but will with the current GIT version.

debbio · Sun May 17, 2015 7:20 pm

Oh this explains a lot of things.. Than I will wait until new version will realised

mcallegari · Sun May 17, 2015 9:31 pm

My bad then ! Totaly missed that commit.
Great job David !
