hmm this is weird
Ive been attaching synths and devices to the inputs on my 2448 mixer and when i reached channel 16 and 17 I couldnt attach the outputs of any synth to the left side inputs. I could however, attach inputs of synths. It is as if they think they are ouputs. I tried reloading the mixer and now the problem has moved to channel 24.
Very odd!
