I want to connect 4 separate microphones for Ambisonic recording. How do I use four input signals (with separate channels) with adc~ 1, adc~ 2, adc~ 3, adc~ 4?and which is the audio setting, number device , number channel etc..??

The device that i'm going to use is an external Edirol UA-1000 with 4 inputs microphonic but using [adc~ 1 2 3 4] these inputs are overlapped and they are not separated in Pure Data. For example from the imput one [adc~1] come out the audio signal of mic 1 and 3.
