hi guys i wanted to let you know something before buying the korg microaudio 22 / 722. i wanted to use it to record and send out audio to process it with other gear i have and back into the microaudio. the problem is that the same mechanism that opens the audio so it plays through the output is the one that closes it. silencing the output when you want to hear what’s coming into the input; if you set it at 12 o clock (in the middle), a feedback loop occurs because you’re hearing both what you’re sending and what you’re receiving. in my case, i'm using reverb. (The problem is the mix knob.) i assume the problem goes for the 722 as well so ye, beware.
