Pops when switching banks

Hi,

I am currently working with ADAU 1787 fastDSP specifically with bank switching to change the gain in a smooth way. After trial and error, I have figured out that when switching banks, the Dynamic Processor/limiter/standard/limiter bloc causes pops when I switch banks, and the same is true for the mixer/multiple control/No slew/Linear block when its value is different between the banks. I have only had no pops when leaving the mixer values constant, removing the limiter blocs and changing the values of my biquads (second order filters).

Is there a way to make those blocs not create pops on my signal when switching from banks A/B/C ? Or is that an inherent limitation of the ADAU 1787?

I would like to avoid having to send the data back to the SigmaDSP for my limiting as I wish to be able to have active noise control in the long term while having the security of a limiter and no pops when switching banks.

Take care,

Elliot.
