Loading filter coefficients to the FastDSP of a ADAU1787 in SigmaStudio

Hello,

I'm working with an EVAL-ADAU1787Z evaluation board in SigmaStudio 4.7. So far I've been using the SigmaDSP to do my signal processing. I now want to move the biquad filtering in my signal chain to the FastDSP. Setting up the actual filters and IO in the FastDSP is simple enough, however I'm running into a few problems.

My filters are set up in a couple of Parametric EQ blocks (as far as I can tell, the only filters available for the fastDSP). The coefficients for the filters will be calculated externally and I would like to load them into the filter blocks. So far, the only way I have found to do this is using a IIR coefficient filter and loading the coefficients from a .txt file. However, this requires me to still click "load" and select a file every time I want to load new coefficients and (more importantly) this has to be done for every biquad separately. My gut feeling says there should be a less cumbersome method to achieve this, since if I understand correctly, all coefficients for a certain parameter bank are stored in a certain piece of the memory. However, I can't find a way of writing to this memory from SigmaStudio. Am I missing something here?

Best regards,
