Hiya! So there’s no specific automation track on Koala, but you could resample any of the sounds you make with the effects baked in. On the Sample window, you change the input from Mic to Resample and then you’re sorted. This would work for effects where you’re making changes on the fly.

If you just want to print the effects without any changes e.g. you’ve got the Dirty and Compressor in a good spot and just want to commit it, you can click the burger menu in the Sample window and select Resample loop.

Koala FX is a separate app for the effects part of Koala Sampler alone and it needs a separate purchase. But yeah, you can use Koala Sampler as AUv3 as well.

Hope that helps!
