Sublab Filter Issue

So if I create a new patch, choose a saw wave (doesn’t matter what wave but this makes the problem more apparent), pull the filter envelope amount all the way down, bring the oscillator send to the filter to 100… I can hear the top end of the saw wave when I pull the filter all the way down. If I continue to hit a note, after a minute or so, the saw wave will begin to filter out. It’s like there’s a crazy delay on the filter? Very strange behavior.

Sublab version 1.1.2

Hey DCJ, what buffer size are you using in your DAW?


Ableton 10 and 512.

Why does it say post must be 20 characters? What happens when the answer takes less?

Hey @DCJ, there is a default setting on the forum for the minimum number of characters you need to type before making a post…not sure why that is to be honest :slight_smile:

I understand the problem you are having now, I’ll have a look into it and get it into the next 1.1.2 build that we’re working on. We designed the filter so that it would minimize noise and processor usage, but in the context of smaller buffer sizes.

I just got Sublab and noticed this too. It seems that both highpass and lowpass filters when set at extreme settings (so that the output would be silent) have nearly no effect. It’s weird because if I raise my buffer size the issue goes away, and if I then lower it again, it stays fixed! It seems like its only an issue when the plugin is loaded at a low buffer size and is not increased then decrased.

Ableton 10 on Mojave.

Hey @lukasschmit,

Just starting back on SubLab 1.1.3 now and will have a look into this. I think both issues are the same thing.

Thanks for the heads up!
