[AudioI] Eurorack breakout for the Octo sound card?

Hi Matt,

I notice that the Ultra 2 sound card supports DC signals; I guess this 
capability partly depends on the codec (CS4265).
The Octo is using the CS42448 codec; can it also support DC signals?

Are you planning to release the schematics for the stereo version of the 
modular preamp?

Thanks
Marc
