Report Strange Problem with Headphones' Stereo in Music Composition & Production Posted June 8, 2013 From what you've described, it sounds like the "mid" is getting canceled out and the "side" remains. That would be why you're hearing more reverb too. Are you applying anything that would change the stereo imaging to your channels? example: Are you turning the 'stereoize' knob in FL Studio (don't use this one anyway). Maybe you could check if something is being canceled from your output by throwing a vectorscope (Wave Candy) on the 'Selected' channel?
