I've been interested in electronics for couple of months now so my knowledge is still very limited. I like microcontrollers so I'm trying to include them in my projects.
I'm trying to build a similar device as Millenium HP4 but with 8 channels. Idea is to have 8 inputs and to map them freely between 8 outputs (you can combine multiple inputs). There are a lot of great articles about splitting, mixing, combining etc. audio signals.
I am stuggling to find a component which can assign one signal input to 0..8 (or 0..16 if available, for stereo sound) outputs. It can be controlled with i2c or simple address inputs (I can control with for example ATMega328p and ATTiny85 slaves).
I'm looking for something like MC74HCT4851A demultiplexer but which can output to multiple channels simultaneously. Seems like I can't find one.. Any recommendations or other ways I can achive what I want?
