First, the workaround: Change the Delay parameter in Compressor dB from 0 to 1 samp.
Now the explanation: the compressor requires a minimum of one sample delay so it can compare the current to previous outputs. In the Capybara code, we always added 1 to the delay time, so it allowed for 0 s in the Delay parameter field. On the Pacarana, a 0 delay wrapped around to become the maximum delay of 4096 samples.
This has now been fixed and will show up in the next Kyma 7 update (but as a workaround, you can explicitly set the delay to 1 samp).
Thanks for reporting this!
