It's been a while since I've used the input echo feature, but it's not behaving like it used to. I load a synth and set the input to the keyboard I want, and input echo is on in the new midi track. When I click on input echo, it only seems to give me the option for on or echo through, but not off. When I go up to the top there is a button for input echo off and on for all tracks, and when I click that, it turns off the input echo on all tracks, but if I turn it on, in the midi track, it doesn't turn back off again, it only toggles between on and through. What am I missing here?
