I’ve done a quick replacement of ducker with compressor.  There is a SIG2 and a 9ka algorithm file in this zip file.

The duckers had the gain parameter set to adc-zero, which doesn’t exist, and I can’t set it to that from VSIG. I left the gaincntl set to 0 for the 4 instances.

If there are issues with this, let me know.

I haven’t tested this, just done the straight substitution.

Let me know if this fixes the issue.
