I'm would like to build sort of a digitally controlled mixer (or more to speak I only need 2 aux sends+ returns). Is has to be able to change "fast" (50-70ms would be ok I guess) when the programs is changed. I have picked an Atmega8 for the purpose for a starting point. I would like to hear if someone has experiences with theese things? I has got to be pro quality (so to speak).
Have anyone tried to use the PWM output + some low pass filters and transistors eg.? (the sound have to be analog all the way through the path). I have the PWM up and running on the Atmega8.
What about digital potmeters? Motor controlled pots? (I have som of thoose bu they are rather slow).
Hope for some ideas!
