i'm a total LMMS newbie.
just downloaded it an hour ago
super fun!

encountered an error
probably due to my absence of skill
or an issue with audio card

on Ubuntu 18.04.5 LTS
when chorus feedback goes above a value (approx 75%)
audios stops
while playhead animation continues

'Great report!
I will take a look at your xpf and see if i can reproduce, it is possible that it is an infinite length wave. That is not 'directly' a bug, but more of a usage issue.
Many plugins can impair sound-output, especially when output is in very low oscillation
I will come back to you asap :)

Hi again sorry for the long wait
Your setting in 3OC are very 'abrasive' :p There are 3 things that almost by design, will crash the output
Image
The worst is that you attempt to have FM on FM, that will always only create really harsh noise, but thats OK! -If you want to create noise, fi. for an explosion or thunder-clap effect, then noise is ok! -But then you need to use an envelope, in order to 'tame' the noise. Here the noise just build up and becomes overwhelming.
That is seriously enhanced because you have max'ed out to of the oscillators, its very seldom you need to max-out an oscillator. You should always look at the out-put either in Mixer
Image
or in the wave-display Image
When either are in the red, then your volume needs to be lowered.
Here is btw an article about making 3OC-presets:

But *ChorusII does have a very narrow sanity area. I recommend you to use *chorusI instead.
