Restarting Quartz Metronome in 4.27

Hi everyone,

This is my first foray into creating a dynamic music system in UE, and I managed to create variations using the Play_Quantized function. Basically each section of the music has different variations and the system picks one randomly, and plays the corresponding file on the appropriate bar and beat (using quantization boundaries). So the music can go in different directions, and some paths take longer than others.

I would like to know if there is any way to restart the metronome so the music plays again from bar 1 after the last file has been played. This doesn’t need to be very accurate timing-wise, a few seconds of silence won’t be an issue.
Because there’s no way to predict the length of a piece of music, I’ll have to “manually” tell the system on what bar/beat to restart the metronome. Is there a way to do that?

Thanks in advance!

Thomas.

Hi Thomas!

It’s a bit tricky to suggest possible solutions without more context, but here’s one that might work:

You could use the Audio Component’s event called “OnAudioFinished” to detect when your music is done playing, then start the music over again. You could reset or re-roll random variables before starting the next music segment. You don’t need to stop and restart the Quartz clock, but you can if you want.

This is a very basic example of how you could set this up. This creates a loop every time the music finishes.

Thanks ebuch!
I’ll try this as soon as I can and will let you know.
