UE4 Quartz: Death & Music (Part 1)

In this tutorial we start setting up UE4’s Quartz to remove a layer of music every time we kill a zombie. We'll go on to use it to power an Aliens-style motion tracker and to update our in-game HUD.

Yes! This tutorial is fantastic! Exactly the kind of thing I've been looking for to get some idea of how to start building the music system for the project I'm working on atm! Thank you so much for making this! Looking forward to part 2!
Also, person woman man camera (tv), that sneaky reference... I lol'd hard

Is there any of this blueprint available somewhere in the marketplace or else?

[@valkyriesound3888]

Hey Chrix, there isn't I'm afraid. I'm using some Marketplace assets and without them it might not really work... :/

Thanks for this tutorial, this is really useful. One question... I'm trying to change the Volume Multiplier for an audio source that is played based on a "beat", it doesn't seem to be making any difference, despite outputting to the screen the Volume Multiplier on the Audio Sources (which are increasing) the actual volume seems to remain unchanged? I'm doing this with a simple SetVolumeMultiplier node, is there an alternative approach that I should use when using Quartz? I've used some drastic values (10, then 50 for example) but its literally no louder?

[@valkyriesound3888]

Hmm... IIRC UE4 caps volume at 4.0 (might be 5!). If anything in your mix already pushes the volume up that high (and not lower) you won't hear any difference. I would try 0.1 as well, just to confirm it's not that. Otherwise... have you set it up so that the Volume Mult is happening before the sound is being triggered? How are you applying the volume mult - is it a node inside the BP or something on the audio component details panel...? :)
